+## 五、现在的代码量够不够？ + +``` +qwen3_6_scripts/ +├── 15个 corex_*.cu 文件 (总计 ~115K 字节 CUDA源码) +├── 14个 build_corex_*.sh (编译脚本) +├── 13个 prebuilt/*.so (已编译二进制) +├── qwen3_5.py (1700+行，模型实现) +├── patch_ops.sh

**corex_moe_index_combine.so 没有prebuilt** — 需要在docker build时在线编译 +2. **corex_gdn_chunk_recurrent.so 没有prebuilt** — 10K字节的GDN prefill kernel，可能是解决NaN的关键 +3. **patch_ops.sh 只编译了 moe_index_combine** — 其余12个走prebuilt安装 + +## 六、下一步行动（代码开发，不是推理） + +### 立即要做的3件事： + +**1. 把 corex_gdn_chunk_recurrent 加入 prebuilt 或 patch_ops.sh 编译链** + +这个.cu存在（10807字节），build脚本也存在，但既没有prebuilt .so，也没在patch_ops.sh里编译。真机上需要： + +```bash +# 在你的BI-V100真机上： +cd /home/dylan/project_6/qwen3_6_scripts +bash build_corex_gdn_chunk_recurrent.sh /usr/local/corex/lib/python3/dist-packages/vllm +# 如果成功，把.so拷到 prebuilt/corex-3.2.3-ivcore10/ +``` + +**2. qwen3_5.py GDN prefill路径需要对接 chunk_recurrent kernel** + +当前qwen3_5.py的GDN prefill fallback是纯PyTorch `_torch_chunk_gated_delta_rule`，产生NaN。corex_gdn_chunk_recurrent.cu 是 fp32 accumulation 的 kernel — 应该能解决NaN。需要在qwen3_5.py里加上对应的 import + dispatch。 + +**3. 把 corex_fused_paged_prefill_split4.cu precompile** + +这个20K字节的kernel对应prefill attention加速，prebuilt目录有 `corex_fused_paged_prefill.so`（可能是同一个的改名），需要确认对应关系。 + +### 在真机上验证步骤： + +```bash +# 单卡验证： +cd /home/dylan/project_6 +python3 -c " +import torch +# 测试prebuilt SO能否加载 +import importlib.util +spec = importlib.util.spec_from_file_location('corex_gdn_causal_conv', + 'qwen3_6_scripts/prebuilt/corex-3.2.3-ivcore10/corex_gdn_causal_conv.so') +mod = importlib.util.module_from_spec(spec) +spec.loader.exec_module(mod) +print('corex_gdn_causal_conv loaded:', dir(mod)) +" +``` + +## 七、commit 9ff2450（能得分的版本） + +这个commit不在当前仓库里。你说它是 `clean: remove build artifacts from docker context`，date Aug 12 07:58。这意味着它是在current HEAD (17fdf7e2) 之后的commit，可能在另一个branch或还没push。 + +**需要你执行：** +```bash +git log --all --oneline | grep 9ff2450 +# 或者 +git push origin main # 如果在真机上有unpushed commits +``` + +## 八、ex_engine upstream搬运清单 + +ex_engine里有大量代码但 **没有接入 patch_ops.sh 部署链**。以下是已有但未使用的： + +| 文件 | 功能 | upstream来源 | 接入状态 |

Gemm device-level operator. This is an interface to efficient CUTLASS GEMM kernels that may + be invoked from host code. + + The contributions of this class are: + + 1. At compile time, it maps data types and high-level structural parameters onto + specific CUTLASS components. + + 2. At runtime, it maps logical arguments to GEMM problems to kernel parameters. + + 3. At runtime, it launches kernels on the device. + + The intent is to provide a convenient mechanism for interacting with most plausible GEMM + configurations for each supported architecture. Consequently, not all parameters are exposed + to the top-level interface. Rather, sensible defaults at each level of the CUTLASS hierarchy + are selected to tradeoff simplicity of the interface with flexibility. We expect + most configurations to be specified at this level. Applications with more exotic requirements + may construct their kernels of interest using CUTLASS components at the threadblock, warp, + and thread levels of abstraction. + + CUTLASS exposes computations using the functor design pattern in which objects compose some + internal state with an overloaded function call operator. This enables decoupling of + initialization from execution, possibly reducing overhead during steady state phases of + application execution. + + CUTLASS device-level operators expose an Arguments structure encompassing each logical + input to the computation. This is distinct from the kernel-level Params structure pattern + which contains application-specific precomputed state needed by the device code. + + Example of a CUTLASS GEMM operator implementing the functionality of cuBLAS's SGEMM NN + is as follows: + + // + // Instantiate the CUTLASS GEMM operator. + // + + cutlass::gemm::device::Gemm< + float, + cutlass::layout::ColumnMajor, + float, + cutlass::layout::ColumnMajor, + float, + cutlass::layout::ColumnMajor + > gemm_op; + + // + // Launch the GEMM operation on the device + // + + cutlass::Status status = gemm_op({ + {m, n, k}, // GemmCoord problem_size, + {A, lda}, // TensorRef ref_A, + {B, ldb}, // TensorRef ref_B, + {C, ldc}, // TensorRef ref_C, + {D, ldd}, // TensorRef ref_D, + {alpha, beta} // EpilogueOutputOp::Params epilogue_op_params + }); + + + A simplified view of the template is listed below. + + template < + /// Element type for A matrix operand + typename ElementA, + + /// Layout type for A matrix operand + typename LayoutA, + + /// Element type for B matrix operand + typename ElementB, + + /// Layout type for B matrix operand + typename LayoutB, + + /// Element type for C and D matrix operands + typename ElementC, + + /// Layout type for C and D matrix operands + typename LayoutC, + + /// Element type for internal accumulation + typename ElementAccumulator, + + /// Operator class tag + typename OperatorClass, + + /// Tag indicating architecture to tune for.

Gemm device-level operator. This is an interface to efficient CUTLASS GEMM kernels that may + be invoked from host code. + + The contributions of this class are: + + 1. At compile time, it maps data types and high-level structural parameters onto + specific CUTLASS components. + + 2. At runtime, it maps logical arguments to GEMM problems to kernel parameters. + + 3. At runtime, it launches kernels on the device. + + The intent is to provide a convenient mechanism for interacting with most plausible GEMM + configurations for each supported architecture. Consequently, not all parameters are exposed + to the top-level interface. Rather, sensible defaults at each level of the CUTLASS hierarchy + are selected to tradeoff simplicity of the interface with flexibility. We expect + most configurations to be specified at this level. Applications with more exotic requirements + may construct their kernels of interest using CUTLASS components at the threadblock, warp, + and thread levels of abstraction. + + CUTLASS exposes computations using the functor design pattern in which objects compose some + internal state with an overloaded function call operator. This enables decoupling of + initialization from execution, possibly reducing overhead during steady state phases of + application execution. + + CUTLASS device-level operators expose an Arguments structure encompassing each logical + input to the computation. This is distinct from the kernel-level Params structure pattern + which contains application-specific precomputed state needed by the device code. + + Example of a CUTLASS GEMM operator implementing the functionality of cuBLAS's SGEMM NN + is as follows: + + // + // Instantiate the CUTLASS GEMM operator. + // + + cutlass::gemm::device::Gemm< + float, + cutlass::layout::ColumnMajor, + float, + cutlass::layout::ColumnMajor, + float, + cutlass::layout::ColumnMajor + > gemm_op; + + // + // Launch the GEMM operation on the device + // + + cutlass::Status status = gemm_op({ + {m, n, k}, // GemmCoord problem_size, + {A, lda}, // TensorRef ref_A, + {B, ldb}, // TensorRef ref_B, + {C, ldc}, // TensorRef ref_C, + {D, ldd}, // TensorRef ref_D, + {alpha, beta} // EpilogueOutputOp::Params epilogue_op_params + }); + + + A simplified view of the template is listed below. + + template < + /// Element type for A matrix operand + typename ElementA, + + /// Layout type for A matrix operand + typename LayoutA, + + /// Element type for B matrix operand + typename ElementB, + + /// Layout type for B matrix operand + typename LayoutB, + + /// Element type for C and D matrix operands + typename ElementC, + + /// Layout type for C and D matrix operands + typename LayoutC, + + /// Element type for internal accumulation + typename ElementAccumulator, + + /// Operator class tag + typename OperatorClass, + + /// Tag indicating architecture to tune for.

Gemm device-level operator. This is an interface to efficient CUTLASS GEMM kernels that may + be invoked from host code. + + The contributions of this class are: + + 1. At compile time, it maps data types and high-level structural parameters onto + specific CUTLASS components. + + 2. At runtime, it maps logical arguments to GEMM problems to kernel parameters. + + 3. At runtime, it launches kernels on the device. + + The intent is to provide a convenient mechanism for interacting with most plausible GEMM + configurations for each supported architecture. Consequently, not all parameters are exposed + to the top-level interface. Rather, sensible defaults at each level of the CUTLASS hierarchy + are selected to tradeoff simplicity of the interface with flexibility. We expect + most configurations to be specified at this level. Applications with more exotic requirements + may construct their kernels of interest using CUTLASS components at the threadblock, warp, + and thread levels of abstraction. + + CUTLASS exposes computations using the functor design pattern in which objects compose some + internal state with an overloaded function call operator. This enables decoupling of + initialization from execution, possibly reducing overhead during steady state phases of + application execution. + + CUTLASS device-level operators expose an Arguments structure encompassing each logical + input to the computation. This is distinct from the kernel-level Params structure pattern + which contains application-specific precomputed state needed by the device code. + + Example of a CUTLASS GEMM operator implementing the functionality of cuBLAS's SGEMM NN + is as follows: + + // + // Instantiate the CUTLASS GEMM operator. + // + + cutlass::gemm::device::Gemm< + float, + cutlass::layout::ColumnMajor, + float, + cutlass::layout::ColumnMajor, + float, + cutlass::layout::ColumnMajor + > gemm_op; + + // + // Launch the GEMM operation on the device + // + + cutlass::Status status = gemm_op({ + {m, n, k}, // GemmCoord problem_size, + {A, lda}, // TensorRef ref_A, + {B, ldb}, // TensorRef ref_B, + {C, ldc}, // TensorRef ref_C, + {D, ldd}, // TensorRef ref_D, + {alpha, beta} // EpilogueOutputOp::Params epilogue_op_params + }); + + + A simplified view of the template is listed below. + + template < + /// Element type for A matrix operand + typename ElementA, + + /// Layout type for A matrix operand + typename LayoutA, + + /// Element type for B matrix operand + typename ElementB, + + /// Layout type for B matrix operand + typename LayoutB, + + /// Element type for C and D matrix operands + typename ElementC, + + /// Layout type for C and D matrix operands + typename LayoutC, + + /// Element type for internal accumulation + typename ElementAccumulator, + + /// Operator class tag + typename OperatorClass, + + /// Tag indicating architecture to tune for.

Whereas writing +high performance kernels at scale which works for multiple problem sizes with good abstractions is +really hard. CUTLASS solves this problem by providing simplified abstractions to compose +multiple sections of gemm kernel. When used properly, the kernels can hit peak performance of GPU +easily. + +CUTLASS divides a kernel into hierarchical composable sections. Which means, at each thread, warp +and thread-block level, they compute on their own tile-size with higher level of tile sizes being +composed from lower level ones. Multiple thread-tiles (tile size each thread computes) can be used +to form warp-tiles (tile size each warp computes) and multiple warp tiles can be used to compute +threadblock-tile (tile size computed by a threadblock). + +In thie example, we split variable initialization into +1. Setting up data properties : describes how matrices are laid out in the memory and how the kernel +can view them (logical to physical mapping) +2. Setting up computation properties : describes how the above set matrices will be used to compute +output of matrix multiplication. + +First, we setup the data types of matrices A, B, C and D along with alpha, beta as the equation for +GEMM is D = alpha * A * B + beta * C. In CUTLASS, the kernels first compute A * B and leaves the +rest of the computation to end of the kernel as alpha * X + beta * C is a simple element-wise +operation on X (A * B) and C. We call this as epilogue of kernel. Hence, we setup data types for +alpha and beta to be equal to ElementComputeEpilogue = int32_t. As we want to use MMA instructions +on Turing and they support 8-bit signed integer (int8_t), we use data type for elements in input +matrix A and B as int8_t. Volta also supports accumulation of partial dot product to int32_t, which +can store wider range of numbers, we use it as data type of output matrix elements and accumulation. +We convey this to CUTLASS kernel by initializing template variables ElementAccumulator (int32_t), +ElementComputeEpilogue (int32_t), ElementInputA (int8_t), ElementInputB (int8_t), ElementOutput +(int32_t). Communicating just the data type is not enough. As the data is laid out linearly in +memory, we have to convey the layout of matrices. We do that by initializing template variable +LayoutInputA to column major cutlass variable, LayoutInputB to row major and LayoutOutput to row +major. Next, we setup rules to comptue alpha * X + beta * C which is called epilogue of the kernel. +We initialize template variable EpilogueOp, which takes the data type of output ElementOutput +(int32_t), the number of elements per vector memory access (16), data type of accumulator (int32_t) +and data type of computation of linear combination (alpha * X + beta * C). + +Now that we setup the properties of data, we have to setup properties of computation. + +Second, we create template variables of tile sizes for thread-block, warp and mma-op to 128x256x64, +64x64x16, 8x8x16 (MxNxK) respectively. When passed to instantiate CUTLASS GEMM kernel, it internally +deduce the amount of threads needed per thread-block, amount of shared memory, storing data in +bank-conflict free manner, and ton of other variables required to compose, intialize and launch a +high performance GEMM kernel. This is the beauty of CUTLASS, it relieves developer from +understanding and coding complicated hardware optimizations which can easily go wrong. + +CUTLASS also supports multiple MMA pipelines in a threadblock. What are MMA pipelines? MMA pipelines +constitute the whole process of loading input data from global memory to shared memory, loading data +from shared memory to registers, doing matrix multiplication, store to global memory. The below flow +sequence shows a typical mma pipeline. + +matrix in global memory -> registers -> tile in shared memory -> registers -> mma -> registers -> +output to global memory + +The problem with single pipeline is, each stage is synchronous which means, each stage has to wait +until the previous finished executing. There are stages in the pipeline which do not have fixed +latency, for example, the loads from global memory and shared memory. Therefore, we can add one more +pipeline with a phase shift in mma kernel to hide latency from global and shared memory loads. +Finally, the pipeline in a kernel looks like + +(1) matrix in global memory -> (2) registers -> (3) tile in shared memory -> (4) registers -> (5) +mma -> (6) registers -> (7) output to global memory (1) -> (2) -> (3) matrix in global +memory -> (4) registers -> (5) tile in shared memory -> (6) registers -> (7) mma -> (8) registers -> +(9) output to global memory + +This way, you can hide the second global memoroy load latency by doing computation on already loaded +input data. + +There are few more template variables initialized such as, which threadblock tile of output matrix +is done which threadblock launched on an SM, CUDA SM architecture of GPU you want to run on. + +These are all put together to create a template variable which describes CUTLASS GEMM kernel using +cutlass::gemm::device::Gemm template. + +The next step is to intialize physical data, instantiate and initialize CUTLASS kernel and run it. +We use CUTLASS utilities to initialize, fill, compare matrices as they are simple and doesn't come +in the way of learning CUTLASS. + +Once all the matrices are initialized and filled with data, create arguments tuple to launch CUTLASS +kernel which takes problem size (M = 5120, N = 4096 and K = 4096), matrices, alpha, beta and the +important one, split k-dimension factor. Along with that, we query CUTLASS if any scratch-space +memory required by the kernel we instantiated. If yes, we create it and pass it along with other +arguments created to intialize CUTLASS kernel then, the kernel is launched. + +In this example, we later on launch a reference gemm kernel (from CUTLASS utilities) to compare if +the output from CUTLASS kernel is same as reference GEMM kernel. +*/ + +#include + +#include "cutlass/cutlass.h" +#include "cutlass/gemm/device/gemm.h" +#include "cutlass/util/host_tensor.h" +#include "cutlass/util/reference/device/gemm.h" +#include "cutlass/util/reference/host/tensor_compare.h" +#include "cutlass/util/reference/host/tensor_copy.h" +#include "cutlass/util/reference/host/tensor_fill.h" +#include "cutlass/util/tensor_view_io.h" +#include "helper.h" + +// The code section below describes datatype for input, output matrices and computation between +// elements in input matrices. +using ElementAccumulator = int32_t; // <- data type of accumulator +using ElementComputeEpilogue = ElementAccumulator; // <- data type of epilogue operations +using ElementInputA = int8_t; // <- data type of elements in input matrix A +using ElementInputB = int8_t; // <- data type of elements in input matrix B +using ElementOutput = int32_t; // <- data type of elements in output matrix D + +// The code section below describes matrix layout of input and output matrices.

Algorithm Decomposition (Three Levels from CCCL) + +### Level 1: Warp Reduce (from `warp_reduce_shfl.cuh`) + +**CCCL pattern:** `shfl.sync.down` butterfly reduction in log2(32) = 5 steps. +Each step: `output = reduction_op(input, ShuffleDown(input, 1 << step))`. + +**In attention:** Within one warp (32 threads), each thread holds QK^T scores +for a subset of KV tokens. Warp reduce computes: +- `max_score = warp_reduce(scores, max_op)` — for softmax numerical stability +- `exp_sum = warp_reduce(exp(scores - max_score), plus_op)` — softmax denominator +- `weighted_v = warp_reduce(exp(scores - max_score) * V[t], plus_op)` — numerator + +This is a **compound reduction** — the same pattern as CCCL's `summary_statistics.cu` +where (count, mean, M2) are reduced together with a custom binary op. + +**Our compound type:** +``` +struct attention_partial { + float max_score; // running max of QK^T + float exp_sum; // sum of exp(score - max_score) + float weighted_v[D]; // sum of exp(score - max_score) * V +}; +``` + +**Binary op** (from `summary_statistics.cu`): +``` +attention_partial combine(attention_partial a, attention_partial b) { + float new_max = max(a.max_score, b.max_score); + float scale_a = exp(a.max_score - new_max); + float scale_b = exp(b.max_score - new_max); + return { + new_max, + scale_a * a.exp_sum + scale_b * b.exp_sum, + scale_a * a.weighted_v + scale_b * b.weighted_v // element-wise + }; +} +``` + +This is exactly the online softmax from Flash Attention. +It's also exactly CCCL's binary reduction op pattern. + +### Level 2: Block Reduce (from `block_reduce_warp_reductions.cuh`) + +**CCCL pattern:** Each warp produces a `warp_aggregate`. Lane 0 of each warp +writes it to `SMEM warp_aggregates[warp_id]`. Then thread 0 serially reduces +across warps: +``` +for (warp_idx = 1; warp_idx < warps; ++warp_idx) + aggregate = reduction_op(aggregate, warp_aggregates[warp_idx]); +``` + +**In attention:** One thread block processes one partition of the KV sequence +(e.g., PARTITION_SIZE = 512 tokens). Multiple warps within the block each handle +a chunk of these 512 tokens. + +- Warp 0: tokens 0..63 (BLOCK_N=64 at a time, or 32 for head_dim=256) +- Warp 1: tokens 64..127 +- ... +- Warp W-1: tokens (W-1)*64..511 + +Each warp produces an `attention_partial`. Block reduce merges them: +``` +__shared__ attention_partial warp_partials[NUM_WARPS]; +warp_partials[warp_id] = my_warp_result; +__syncthreads(); +if (threadIdx.x == 0) { + attention_partial block_result = warp_partials[0]; + for (int w = 1; w < NUM_WARPS; w++) + block_result = combine(block_result, warp_partials[w]); + // Write block_result to global: tmp_output, exp_sums, max_logits +} +``` + +**SMEM layout for attention_partial at head_dim=256:** +- max_score: 4 bytes +- exp_sum: 4 bytes +- weighted_v[256]: 256 × 4 = 1024 bytes +- Total per warp: 1032 bytes +- For 4 warps: 4128 bytes (fits easily in 48KB) + +### Level 3: Cross-Partition Coordination (from `agent_scan.cuh` + decoupled lookback) + +**CCCL pattern:** `TilePrefixCallbackOp` implements decoupled lookback. +Each tile block: +1. Computes its local aggregate +2. Publishes local aggregate to global `tile_state` (PARTIAL status) +3. Warp 0 looks back through predecessor tiles: + - If predecessor has INCLUSIVE status → directly use its prefix + - If predecessor has PARTIAL status → accumulate and keep looking back +4. Once prefix is resolved, update own status to INCLUSIVE + +**In attention (V2):** Each partition block has its `attention_partial`. +The cross-partition reduction is simpler than scan because attention +partitions are **commutative** — we don't need prefix sums, just a +global reduce. + +But the coordination pattern is the same: +1. Each partition block writes its (max_logit, exp_sum, partial_output) to + global memory: `tmp_output[seq, head, partition, :]` +2. A separate reduction kernel (or the last partition block) reads all + partitions and does the final combine. + +**Simplification over CCCL's lookback:** Since attention partitions are +independent (no prefix dependency), we don't need the lookback polling loop. +Each partition can run fully independently. The reduction is a simple +parallel reduce over `num_partitions` compound values. + +For 100K tokens / 512 partition_size = ~200 partitions. +200 `attention_partial` values × (4 + 4 + 256×4) = 200 × 1032 = ~200KB. +One block can reduce all 200 in registers + SMEM. + +--- + +## 3. Paged K/V Gather (from `block_load.cuh` + `cache_modified_input_iterator.cuh`) + +**CCCL pattern:** `BlockLoadWarpTranspose` loads contiguous global memory +into a striped register layout that enables coalesced access. Each thread +loads `ITEMS_PER_THREAD` elements, and the warp transposes them so each +thread gets its tile of the data. + +**In paged attention:** K/V are not contiguous — they're indexed through +`block_tables[seq, logical_block] → physical_block`. +- Key cache: `[num_blocks, kv_heads, head_dim/x, block_size, x]` + where x = 16/sizeof(dtype) is the packing factor +- Value cache: `[num_blocks, kv_heads, head_dim, block_size]` + +The gather pattern (from `prefix_prefill.py`, which works on BI-V100): +``` +# For BLOCK_N tokens starting at position start_n: +token_ids = start_n + tl.arange(0, BLOCK_N) +logical_blocks = token_ids // block_size +within_block = token_ids % block_size +physical_blocks = tl.load(block_tables + seq * stride + logical_blocks * stride) + +# K gather: compute 2D offset array [HEAD_DIM, BLOCK_N] +off_k = (physical_blocks[None, :] * stride_kc_b + + kv_head * stride_kc_h + + (offs_d[:, None] // x) * stride_kc_dx + + within_block[None, :] * stride_kc_bs + + (offs_d[:, None] % x) * stride_kc_x) +k = tl.load(key_cache + off_k, mask=valid_mask) +``` + +This is an **indirect gather** — the physical block ID comes from a table lookup. +CCCL's `CacheModifiedInputIterator` handles the cache hint part, but the +indirect indexing is our addition. + +**Memory access pattern:** +- block_tables lookup: 1 global read per BLOCK_N tokens (amortized) +- K gather: BLOCK_N × HEAD_DIM / x global reads (scattered by physical block) +- V gather: BLOCK_N × HEAD_DIM global reads (similar scatter) + +For BLOCK_N=32, HEAD_DIM=256, x=8: 32 × 32 = 1024 reads for K per iteration. +At 16 bytes per read (128-bit): 16KB per K load. +V is similar. Total per iteration: ~32KB — fits in L2 (6MB on BI-V100). + +--- + +## 4. GQA (Grouped Query Attention) Handling + +**The insight:** 6 query heads share 1 KV head. Loading KV once and +computing 6 sets of QK^T scores is 6x more compute-efficient than +loading KV 6 times. + +**CCCL analogy:** This is like `BlockReduce` where we have 6 different +reduction operations on the same input data. CCCL doesn't have this exact +pattern, but the principle is: share data loads, parallelize computation. + +**Implementation:** +- Each thread block handles one `(seq, kv_head, partition)` triple +- Within the block, 6 query heads are processed simultaneously +- Q vectors: 6 × HEAD_DIM = 6 × 256 = 1536 values in registers (per thread + this is 1536/32 = 48 registers — feasible) +- K/V: loaded once for the kv_head, broadcast across all 6 query heads +- Scores: 6 × BLOCK_N values per iteration +- Weighted V: 6 × HEAD_DIM per thread's accumulator + +This reduces K/V cache reads by 6x (the GQA ratio). + +Grid: `(num_seqs, num_kv_heads, num_partitions)` = `(1, 4, 200)` = 800 blocks +instead of `(1, 24, 200)` = 4800 blocks. + +Each block does 6x more compute but reads KV only once. + +--- + +## 5.

推理性能的全过程。方法论来自 Simon Boehm 的 SGEMM worklog——不做假设，每一个论断都在真机上验证，每改一个变量就重新测量。 + +不同的是，Simon 优化的是一个单独的矩阵乘 kernel，问题边界清晰。我们面对的是一个完整的推理系统：36 层 decoder，每层包含注意力、MoE、归一化、AllReduce，外加 embedding 和 lm_head。87 毫秒的 decode step 里有几十个不同的操作，瓶颈不在一个地方。如果只盯着一个 kernel 优化，可能省了 2 毫秒但忽略了别处的 20 毫秒。 + +所以第一步不是写 kernel，是量清楚时间花在了哪里。 + + +第一部分：硬件 + +GPU 是 Iluvatar BI-V100，32 GB HBM2，CUDA 10.2 兼容。用 128 MB 连续拷贝测得实际全局内存带宽 584.2 GB/s。FP16 算力约 32 TFLOPS。 + +BI-V100 和 NVIDIA GPU 最大的差异是 warp 宽度。NVIDIA 的 warp 是 32 个线程，BI-V100 是 64 个。这个差异不在任何公开文档里，是通过 CUDA kernel 内部的 warpSize 变量测出来的。 + +这个差异带来了两个后果。第一，__shfl_down_sync 在 64 线程 warp 上的行为。我写了测试 kernel，让 64 个 lane 各贡献 1.0，用 __shfl_down_sync(0xffffffff, val, offset) 归约，正确结果应该是 64.0。真机测量结果：输出 64.0，完全正确。CoreX 运行时对 32 位 mask 做了兼容处理。 + +第二，__syncwarp 对 shared memory 的可见性。我写了完整的 W2 矩阵向量乘 kernel，用已知数据（全 1 输入，单位权重），正确结果应该是 128.0。用 __syncwarp 做 shared memory 归约但不加 volatile 关键字：输出 32.0，只有正确值的四分之一。加了 volatile：输出 128.0，正确。用 __shfl_down_sync 做归约：输出 128.0，也正确。 + +根因是 CoreX clang++ 编译器在 pragma unroll 的配合下，把 shared memory 的读操作提升到了寄存器中缓存。__syncwarp 只保证线程间的执行顺序同步，不保证 shared memory 写操作的可见性。volatile 强制每次读写都真正访问 shared memory 而不走寄存器。 + +这三个事实——shfl 正确、syncwarp 不保证 smem 可见性、volatile 能修复——全部通过真机测试得到，不是推理。之前有两个版本的 kernel 基于错误的假设（第一个假设 shfl 在 64 线程 warp 上不工作，第二个假设问题在 syncwarp 的 barrier 语义），都产出了错误的结果。在竞赛评测中，错误的 kernel 让模型输出全部变成感叹号。 + + +第二部分：全局 profile——时间花在了哪里 + +用真实的模型

100-200 微秒）、Python 调度开销（每次 kernel launch 的 PyTorch dispatch 约 30 微秒，几百次 launch 加起来）、vLLM scheduler 和 sampling 的 CPU 端逻辑。 + +这个分解立刻指出了几个事实。 + +第一，MoE 确实是最大的单项。但它不是唯一值得优化的。注意力 11.2 毫秒、RMSNorm 4.6 毫秒、Python 调度 ~15 毫秒（估算）——每一项都有几毫秒的优化空间。 + +第二，注意力的耗时随 context length 急剧增长。seq_len=128 时每层只要 62 微秒，seq_len=1024 时 143 微秒，seq_len=4096 时 380 微秒，seq_len=16384 时 1709 微秒。在长对话场景下，注意力会超过 MoE 成为瓶颈。 + +第三，RMSNorm 64 微秒一次、72 次 = 4.6 毫秒。这是纯 Python 手写的 x * rsqrt(mean(x²)+eps) * w，完全可以用 prebuilt 的 corex 或 xllm .so 替代。项目里已经有 xllm_norm.so 和 ix_full_bridge.so 都导出了 rms_norm 函数。 + +第四，LM head 在 TP=4 下是 1.7 毫秒，不算小但也不是瓶颈。如果不做 TP 分片，全量 vocab 是 6.5 毫秒——比一层注意力还大。TP 分片的价值在这里很明显。 + + +第三部分：MoE 的 Python 回退路径为什么慢 + +当前生产代码的 MoE 路径是纯 PyTorch。在真机上分步测量每个操作： + +w13 index_select（从 256 个 expert 中拷贝 8 个的权重）：115 微秒 +w2

index_select。w13[eids] 拷贝 8.4 MB 数据到一个新 tensor，然后 F.linear 再把这 8.4 MB 读一遍。同一份数据被全局内存读了两次。 + +这就引出了 direct_routed kernel 的设计思路：不做 index_select，在 kernel 里直接用 expert_id 索引到权重矩阵计算点积。消除一次 8.4 MB 的冗余拷贝。 + + +第四部分：direct_routed kernel 的三个迭代 + +第一个版本用了 shared memory 归约，但没加 volatile。评测结果：模型输出全是感叹号。TPS 从 11.5 涨到 14.3——kernel 确实在跑，但数值全错。 + +第二个版本加了 volatile。评测还在跑。 + +第三个版本对 W13 和 W2 两个 kernel 用了不同的归约策略。 + +W13 kernel：每个 warp 做 2048 维点积，64 个 lane 各处理 16 个 half2 值，累加后做一次归约。用 volatile shared memory 归约。真机计时：26.5 微秒。读取 8.4 MB 权重数据，实际带宽 316.7 GB/s，是硬件实测带宽 584.2 GB/s 的 54.2%。 + +W2 kernel：每个 warp 对 8 个 expert 各做 128 维点积。64 个 lane 每次只处理 1 个 half2（因为 128/2/64 = 1），然后做归约。用 volatile shared memory 归约时，真机计时 76.5 微秒。 + +但这 76.5 微秒太慢了。我做了隔离测试，把 W2 kernel 拆成"只读数据不做归约"和"只做归约不读数据"两个版本： + +W2 纯读取（不归约）：15.3 微秒 +W2 纯归约（不读取）：69.2 微秒 +W2 完整（volatile smem）：76.5 微秒 +W2 用 shfl_down：16.8 微秒 + +90% 的时间在做 volatile smem 归约。原因是 W2 的 128 维点积在 64 线程 warp 上太短——每个 lane 只有 1 个 half2 的计算（2 次 FMA），然后要做 6 轮 volatile smem barrier 同步。每轮同步是一次 smem 写、一次 barrier、一次 smem 读。6 轮 × 8 个 expert = 48 次 barrier。barrier 的开销远远超过了 2 次 FMA 的计算。 + +而 __shfl_down_sync 只需要 6 条 shuffle 指令，不走 shared memory，延迟低几十倍。之前的 reduction 正确性测试已经确认 shfl_down 在 BI-V100 上是正确的。单独测试 W2 shfl_down 版本的数值正确性：100 个随机种子全部通过，max_diff < 0.1。 + +所以第三个版本的策略是：W13 用 volatile smem（因为 W13 的归约只做 1 次，26.5 微秒中归约不是大头），W2 用 shfl_down（因为 W2 要做 8 次归约，smem 版本 90% 时间在归约）。 + +第三个版本的真机预期计时：W13 26.5 微秒 + SiluAndMul 19.5 微秒 + W2 16.8 微秒 = 62.8 微秒每层。加上共享 expert 149.7 微秒，每层 MoE 模块约 213 微秒。36 层约 7.7 毫秒。 + +对比 Python 回退路径的 21.6 毫秒，节省约 13.9 毫秒。 + + +第五部分：注意力——随 context length 增长的瓶颈 + +真机测量了不同 context length 下单层注意力的耗时： + +seq_len=128：62 微秒 +seq_len=512：92 微秒 +seq_len=1024：143 微秒 +seq_len=4096：380 微秒 +seq_len=16384：1709 微秒 + +这是纯 PyTorch 的 Q@K^T + softmax + attn@V 路径（xformers SDPA fallback），因为 BI-V100 不支持 head_dim=128 的 cudnn flash attention。 + +32 层全注意力在 seq_len=1024 时是 11.2 毫秒，在 seq_len=4096 时是 22.0 毫秒，在 seq_len=16384 时是 75.9 毫秒。长对话场景下注意力单项就会超过整个 MoE 的时间。 + +这里的优化空间在于用更高效的 attention kernel 替代 PyTorch 手写路径。项目中有 corex_fused_paged_prefill.so 用于 prefill 阶段的分页注意力，但 decode 阶段的 paged attention 可能需要额外的 kernel。另一个方向是用 corex_paged_kv_gather.so 做 KV cache 的高效读取。 + +注意力的另一个特点是它是 memory-bound 的（M=1 的 GEMV），但数据量随 seq_len 线性增长。每个 head 读取 seq_len × head_dim × 2 × 2 字节（K 和 V），6 个 head 在 seq_len=16384 时读 6 × 16384 × 128 × 2 × 2 = 48 MB。在 584 GB/s 下理论需要 82 微秒——实际 1709 微秒，效率只有 4.8%。说明不是带宽瓶颈，是 Python 调度和 kernel launch 的开销。 + + +第六部分：RMSNorm——被忽视的 4.6 毫秒 + +72 次 RMSNorm，每次 64 微秒，共 4.6 毫秒。这个数字比一层注意力还大。 + +当前代码用的是手写 PyTorch：x * rsqrt(mean(x²) + eps) * weight。这涉及 4 个 PyTorch 操作（pow、mean、rsqrt、mul），每个都是一次 CUDA kernel launch。 + +项目中已经有多个 prebuilt .so 可以做 fused RMSNorm： + +xllm_norm.so 导出 rms_norm 和 fused_add_rms_norm +ix_full_bridge.so 导出 rms_norm 和 fused_add_rms_norm +corex_attn_head_rms_norm.so 用于注意力层的 head-wise RMSNorm + +如果 fused RMSNorm kernel 能把 64 微秒降到 10 微秒（一次 kernel launch + 一次读写），72 次就从 4.6 毫秒降到 0.7 毫秒，省 3.9 毫秒。 + +但这些 .so 是否真的能正确加载和运行，需要在真机上验证。之前的经验告诉我们，prebuilt .so 在 BI-V100 上可能因为 ABI 不兼容、warp 宽度差异、编译器行为不同等原因而产出错误结果。 + + +第七部分：MoE 的 memory-bound 极限 + +回到 Simon Boehm 的核心分析方法。对于每个操作，算清楚三个数字：传输的字节数、执行的浮点运算数、算术强度（FLOPs/byte）。然后对照 roofline 模型判断瓶颈。 + +BI-V100 的 roofline 交叉点：32000 GFLOPS / 584.2 GB/s = 54.8 FLOPs/byte。低于这个值就是 memory-bound。 + +MoE 每层（T=1 decode）： +传输量：12.6 MB（W13 权重 8.4 MB + W2 权重 4.2 MB） +计算量：12.6 MFLOP +算术强度：1.0 FLOPs/byte +状态：极度 memory-bound + +QKV 投影（1x2048 乘 1024x2048）： +传输量：2.0 MB（权重） +计算量：4.2 MFLOP +算术强度：2.1 FLOPs/byte +状态：memory-bound + +LM head TP=4（1x2048 乘 37984x2048）： +传输量：148 MB +计算量：155.7 MFLOP +算术强度：1.1 FLOPs/byte +状态：memory-bound + +注意力 Q@K^T（1x128 乘 128xseq_len，6 heads）： +传输量：6 × seq_len × 128 × 2 字节（读 K cache） +计算量：6 × 2 × 128 × seq_len FLOP +算术强度：1.0 FLOPs/byte +状态：memory-bound + +整个 T=1 decode step 中，没有一个操作能达到 compute-bound。全部是 memory-bound。这和 Simon 的 SGEMM 场景（4092² 矩阵乘，算术强度约 2700）有本质区别。Simon 的优化方向是提高计算效率——blocktiling、warptiling、register caching，让 FMA 单元更忙。我们的优化方向是减少内存传输量和消除调度开销——因为 GPU 的计算单元已经在大部分时间里无事可做了。 + +这不代表 Simon 的 blocktiling 和 warptiling 技术对我们没用。在 prefill 阶段（T>1），MoE 的 GEMM 是 M>1 的矩阵乘，算术强度随 M 增长。当 M=64 时，算术强度约 64 FLOPs/byte，超过 roofline 交叉点，就变成 compute-bound 了。这时 Simon 的技术直接适用。但 decode 阶段（M=1）是另一个世界。 + + +第八部分：调度开销——看不见的 46.5 毫秒 + +纯计算 40.5 毫秒，实际 87 毫秒。差额 46.5 毫秒里有什么？ + +真机测量的空 kernel launch 开销：6.2 微秒。看起来不大。但一个 decode step 有多少次 kernel launch？ + +每层注意力：QKV 投影 1 次 + RoPE 若干次 + 注意力 3 次（Q@K^T、softmax、attn@V）+ 输出投影 1 次 ≈ 6 次 +每层 MoE（fallback 路径）：topk 1 次 + softmax 1 次 + index_select 2 次 + F.linear 1 次 + SiluAndMul 3 次 + bmm 1 次 + 加权求和 2 次 + 共享 expert 3 次 ≈ 14 次 +每层 RMSNorm：4 次小 kernel（pow、mean、rsqrt、mul）× 2 次 ≈ 8 次 +每层 GDN：投影 1 次 + conv 若干 + state update 若干 + query 1 次 + 输出 1 次 ≈ 8 次 +AllReduce：每层 2 次（注意力后 + MoE 后）× 36 层 = 72 次 + +粗算：32 × 6 + 36 × 14 + 72 × 8 + 4 × 8 + 72 + 其他 ≈ 1400 次 kernel launch。 + +但 6.2 微秒是 kernel launch 本身的硬件开销。PyTorch 的 dispatch 还要加上 Python 函数调用、参数检查、tensor metadata 处理。完整的 PyTorch 操作调用大约 20-30 微秒。1400 × 25 = 35 毫秒。加上 72 次 NCCL AllReduce（每次可能 100-200 微秒），72 × 150 = 10.8 毫秒。35 + 10.8 = 45.8 毫秒，和观察到的 46.5 毫秒差额基本吻合。 + +这意味着在当前的系统中，**调度开销和纯计算时间几乎一样大**。优化 kernel 内部效率是一半的战场，减少 kernel launch 次数是另一半。 + +Simon Boehm 的 SGEMM 不存在这个问题，因为一整个矩阵乘就是一个 kernel launch，计算时间远大于 launch 开销。但在 T=1 推理中，每个 kernel 只做几微秒的计算，launch 开销占比可以超过 50%。 + + +第九部分：三条优化路线 + +基于以上测量，优化分三条线并行推进。 + +第一条：减少 MoE 的计算时间。已完成的 direct_routed kernel 把每层 MoE 从 450 微秒降到 63 微秒（W13 26.5 + SiluAndMul 19.5 + W2 16.8）。加上共享 expert 150 微秒，每层 213 微秒，36 层 7.7 毫秒。对比原来的 21.6 毫秒，省 13.9 毫秒。 + +进一步的融合（把 SiluAndMul 合入 W2 kernel，省掉一次 PyTorch dispatch）可以再省 20 微秒每层，36 层约 0.7 毫秒。优先级不如下面两条高。 + +第二条：减少 kernel launch 次数。每个 kernel launch 的 PyTorch 调度开销约 25 微秒。如果能把 MoE 的 14 次 launch 减少到 2 次（W13 + fused_silu_w2_reduce），每层省 12 × 25 = 300 微秒。36 层省 10.8 毫秒。这不需要写新的 CUDA 内核，只需要确保已有的 .so 能正确加载并在代码中被调用，替代 Python fallback 路径。 + +类似地，RMSNorm 72 次 × 4 小 kernel = 288 次 launch。如果用 fused RMSNorm .so 替代，每次从 4 次 launch 变成 1 次，减少 216 次 launch，省 216 × 25 = 5.4 毫秒。 + +第三条：减少 AllReduce 开销。72 次 NCCL AllReduce 可能占了 10+ 毫秒。可以通过计算-通信重叠（overlap）来隐藏部分延迟——在上一层的 AllReduce 进行时，下一层的投影已经开始计算。这需要 CUDA stream 层面的改造。 + + +第十部分：W13 和 W2 kernel 的详细分析 + +回到 Simon Boehm 的逐 kernel 分析方法。 + +W13 kernel 的工作是：input(1, 2048) × W13[expert_ids[k], row, :] → gate_up(8, 256)。2048 个 warp，每个 warp 做一个 2048 维点积。64 个 lane 各加载 16 个 half2（2048/2/64），用 fmaf 累加，最后用 volatile smem 做 warp 级归约。 + +内存访问模式：每个 warp 读一整行权重 2048 × 2 = 4 KB。64 个 lane 按 half2 读取，lane i 读地址 weight_base + i*4，lane i+1 读 weight_base + (i+1)*4。连续 lane 读连续地址，步长 4 字节——合并访问。一次 warp 级事务传输 64 × 4 = 256 字节。每行 4 KB 需要 16 次 warp 事务。 + +输入向量 4 KB 被 2048 个 warp 共享，第一个 warp 读完后进入 L2 缓存，后续 warp 命中 L2。 + +总流量：2048 行 × 4 KB = 8.4 MB，全是冷读，无复用。 +实测：26.5 微秒。 +带宽：8.4 MB / 26.5 μs = 316.7 GB/s = 实测峰值的 54.2%。 + +54% 的效率合理吗？512 个 block 分配到约 80 个 SM，每 SM 约 6 个 block，24 个 warp。BI-V100 每 SM 最多约 48 个 warp，occupancy 约 50%。不够高，无法完全隐藏全局内存延迟，但对于 2048 个独立点积来说已经是合理的并行度了。 + +W2 kernel 的工作是：activated(8, 128) × W2[expert_ids[k], h, :] → expert_out(2048)，带加权求和。2048 个 warp，每个对应一个输出 hidden dimension，循环 8 个 expert 做 128 维点积。 + +这里的问题前面已经分析过了：每个 lane 只做 1 个 half2 的计算（2 次 FMA），然后需要 warp 级归约。volatile smem 版本 90% 的时间在做归约。换成 __shfl_down_sync 后：16.8 微秒。 + +16.8 微秒读 4.2 MB，带宽 250 GB/s，效率 42.8%。考虑到每次读取只有 256 字节（128 × 2 = 256 字节），粒度比 W13 的 4 KB 小很多，42.8% 也是合理的。 + +Simon 在 Kernel 6 里做了向量化加载（float4，128 位，一次读 4 个 float）来减少指令数。对 W2 来说，128 个 half 可以用 float4 加载（每次 16 字节 = 8 个 half），64 个 lane 读 128/8 × 16 = 256 字节......但 128/8 = 16 个 float4，64 个 lane 中只有 16 个有工作。这会让 3/4 的 lane 空闲，不一定更快。向量化在 W13（2048 维）上更有价值。 + + +第十一部分：Simon Boehm 方法论的适用性总结 + +Simon 的 SGEMM worklog 按顺序做了这些优化： + +naive kernel → 修复全局内存合并访问 → 共享内存缓存 → 1D blocktiling（每线程多个结果）→ 2D blocktiling → 向量化加载 → autotuning → warptiling + +每一步的核心逻辑是在更高层级的存储上复用数据——从全局内存到共享内存到寄存器。他的问题 domain（大方阵乘法）允许这种复用，因为同一个 A 矩阵的行会被多列 B 使用。 + +在 T=1 推理中，这种复用几乎不存在。M=1 意味着每个权重值只被用一次，没有 blocktiling 的空间。唯一的复用是输入向量被所有 warp 共享，而这已经通过 L2 缓存实现了。 + +但 Simon 的方法论——测量、隔离、验证、再测量——完全适用。我们用它发现了 volatile smem 的问题（90% 时间在归约），用它隔离了 W2 的瓶颈（读取 15.3 微秒 vs 归约 69.2 微秒），用它验证了 shfl_down 的正确性（100/100 seeds）。 + +在 T>1 的 prefill 阶段，Simon 的技术直接适用。MoE 的 grouped GEMM（M=batch_size，可能是几十到几百）变成了真正的矩阵乘，blocktiling 和 warptiling 能发挥作用。项目中有 gemm_grouped.so 用于这个场景。 + +对于 T=1 的 decode 阶段，优化的核心不是 kernel 内部的数据复用（没有复用空间），而是系统级的开销消除——减少 Python dispatch、减少 kernel launch、fusion、以及利用 prebuilt .so 替代 Python fallback 路径。这是一个不同的优化范式，但分析方法是相同的。 + + +第十二部分：所有真机测量数据汇总 + +硬件参数（真机测量）： +全局内存带宽：584.2 GB/s（128 MB 连续拷贝） +GPU 型号：Iluvatar BI-V100

It behaves as follows: + * + * @par + * - Allocations from the allocator are associated with an @p active_stream. Once freed, + * the allocation becomes available immediately for reuse within the @p active_stream + * with which it was associated with during allocation, and it becomes available for + * reuse within other streams when all prior work submitted to @p active_stream has completed. + * - Allocations are categorized and cached by bin size. A new allocation request of + * a given size will only consider cached allocations within the corresponding bin. + * - Bin limits progress geometrically in accordance with the growth factor + * @p bin_growth provided during construction. Unused device allocations within + * a larger bin cache are not reused for allocation requests that categorize to + * smaller bin sizes. + * - Allocation requests below ( @p bin_growth ^ @p min_bin ) are rounded up to + * ( @p bin_growth ^ @p min_bin ). + * - Allocations above ( @p bin_growth ^ @p max_bin ) are not rounded up to the nearest + * bin and are simply freed when they are deallocated instead of being returned + * to a bin-cache. + * - If the total storage of cached allocations on a given device will exceed + * @p max_cached_bytes, allocations for that device are simply freed when they are + * deallocated instead of being returned to their bin-cache. + * + * @par + * For example, the default-constructed CachingDeviceAllocator is configured with: + * - @p bin_growth = 8 + * - @p min_bin = 3 + * - @p max_bin = 7 + * - @p max_cached_bytes = 6MB - 1B + * + * @par + * which delineates five bin-sizes: 512B, 4KB, 32KB, 256KB, and 2MB + * and sets a maximum of 6,291,455 cached bytes per device + * + */ +struct CachingDeviceAllocator +{ + //--------------------------------------------------------------------- + // Constants + //--------------------------------------------------------------------- + + /// Out-of-bounds bin + static constexpr unsigned int INVALID_BIN = (unsigned int) -1;

These annotations provide + * information to tools like Nsight Systems to improve visualization of + * application timelines. + * + * \ref RANGES are one of the most commonly used NVTX constructs for annotating + * a span of time. For example, imagine a user wanted to see every time a + * function, `my_function`, is called and how long it takes to execute. This can + * be accomplished with an NVTX range created on the entry to the function and + * terminated on return from `my_function` using the push/pop C APIs: + * + * \code{.cpp} + * void my_function(...) { + * nvtxRangePushA("my_function"); // Begins NVTX range + * // do work + * nvtxRangePop(); // Ends NVTX range + * } + * \endcode + * + * One of the challenges with using the NVTX C API is that it requires manually + * terminating the end of the range with `nvtxRangePop`. This can be challenging + * if `my_function()` has multiple returns or can throw exceptions as it + * requires calling `nvtxRangePop()` before all possible return points. + * + * NVTX C++ solves this inconvenience through the "RAII" technique by providing + * a `nvtx3::scoped_range` class that begins a range at construction and ends + * the range on destruction. The above example then becomes: + * + * \code{.cpp} + * void my_function(...) { + * nvtx3::scoped_range r{"my_function"}; // Begins NVTX range + * // do work + * } // Range ends on exit from `my_function` when `r` is destroyed + * \endcode + * + * The range object `r` is deterministically destroyed whenever `my_function` + * returns---ending the NVTX range without manual intervention. For more + * information, see \ref RANGES and `nvtx3::scoped_range_in`. + * + * Another inconvenience of the NVTX C APIs are the several constructs where the + * user is expected to initialize an object at the beginning of an application + * and reuse that object throughout the lifetime of the application. For example + * see domains, categories, and registered messages. + * + * Example: + * \code{.cpp} + * nvtxDomainHandle_t D = nvtxDomainCreateA("my domain"); + * // Reuse `D` throughout the rest of the application + * \endcode + * + * This can be problematic if the user application or library does not have an + * explicit initialization function called before all other functions to + * ensure that these long-lived objects are initialized before being used. + * + * NVTX C++ makes use of the "construct on first use" technique to alleviate + * this inconvenience. In short, a function local static object is constructed + * upon the first invocation of a function and returns a reference to that + * object on all future invocations. See the documentation for `nvtx3::domain`, + * `nvtx3::named_category`, `nvtx3::registered_string`, and + * https://isocpp.org/wiki/faq/ctors#static-init-order-on-first-use for more + * information. + * + * Using construct on first use, the above example becomes: + * \code{.cpp} + * struct my_domain{ static constexpr char const* name{"my domain"}; }; + * + * // The first invocation of `domain::get` for the type `my_domain` will + * // construct a `nvtx3::domain` object and return a reference to it. Future + * // invocations simply return a reference. + * nvtx3::domain const& D = nvtx3::domain::get(); + * \endcode + * For more information about NVTX and how it can be used, see + * https://docs.nvidia.com/cuda/profiler-users-guide/index.html#nvtx and + * https://devblogs.nvidia.com/cuda-pro-tip-generate-custom-application-profile-timelines-nvtx/ + * for more information. + * + * \section RANGES Ranges + * + * Ranges are used to describe a span of time during the execution of an + * application. Common examples are using ranges to annotate the time it takes + * to execute a function or an iteration of a loop. + * + * NVTX C++ uses RAII to automate the generation of ranges that are tied to the + * lifetime of objects. Similar to `std::lock_guard` in the C++ Standard + * Template Library. + * + * \subsection scoped_range Scoped Range + * + * `nvtx3::scoped_range_in` is a class that begins a range upon construction + * and ends the range at destruction. This is one of the most commonly used + * constructs in NVTX C++ and is useful for annotating spans of time on a + * particular thread. These ranges can be nested to arbitrary depths. + * + * `nvtx3::scoped_range` is an alias for a `nvtx3::scoped_range_in` in the + * global NVTX domain. For more information about Domains, see \ref DOMAINS. + * + * Various attributes of a range can be configured constructing a + * `nvtx3::scoped_range_in` with a `nvtx3::event_attributes` object. For + * more information, see \ref ATTRIBUTES. + * + * Example: + * + * \code{.cpp} + * void some_function() { + * // Creates a range for the duration of `some_function` + * nvtx3::scoped_range r{}; + * + * while(true) { + * // Creates a range for every loop iteration + * // `loop_range` is nested inside `r` + * nvtx3::scoped_range loop_range{}; + * } + * } + * \endcode + * + * \subsection unique_range Unique Range + * + * `nvtx3::unique_range` is similar to `nvtx3::scoped_range`, with a few key differences: + * - `unique_range` objects can be destroyed in any order whereas `scoped_range` objects must be + * destroyed in exact reverse creation order + * - `unique_range` can start and end on different threads + * - `unique_range` is movable + * - `unique_range` objects can be constructed as heap objects + * + * There is extra overhead associated with `unique_range` constructs and therefore use of + * `nvtx3::scoped_range_in` should be preferred. + * + * \section MARKS Marks + * + * `nvtx3::mark` annotates an instantaneous point in time with a "marker". + * + * Unlike a "range" which has a beginning and an end, a marker is a single event + * in an application, such as detecting a problem: + * + * \code{.cpp} + * bool success = do_operation(...); + * if (!success) { + * nvtx3::mark("operation failed!"); + * } + * \endcode + * + * \section DOMAINS Domains + * + * Similar to C++ namespaces, domains allow for scoping NVTX events. By default, + * all NVTX events belong to the "global" domain. Libraries and applications + * should scope their events to use a custom domain to differentiate where the + * events originate from. + * + * It is common for a library or application to have only a single domain and + * for the name of that domain to be known at compile time. Therefore, Domains + * in NVTX C++ are represented by _tag types_. + * + * For example, to define a custom domain, simply define a new concrete type + * (a `class` or `struct`) with a `static` member called `name` that contains + * the desired name of the domain. + * + * \code{.cpp} + * struct my_domain{ static constexpr char const* name{"my domain"}; }; + * \endcode + * + * For any NVTX C++ construct that can be scoped to a domain, the type + * `my_domain` can be passed as an explicit template argument to scope it to + * the custom domain. + * + * The tag type `nvtx3::domain::global` represents the global NVTX domain. + * + * \code{.cpp} + * // By default, `scoped_range_in` belongs to the global domain + * nvtx3::scoped_range_in<> r0{}; + * + * // Alias for a `scoped_range_in` in the global domain + * nvtx3::scoped_range r1{}; + * + * // `r` belongs to the custom domain + * nvtx3::scoped_range_in r{}; + * \endcode + * + * When using a custom domain, it is recommended to define type aliases for NVTX + * constructs in the custom domain. + * \code{.cpp} + * using my_scoped_range = nvtx3::scoped_range_in; + * using my_registered_string = nvtx3::registered_string_in; + * using my_named_category = nvtx3::named_category_in; + * \endcode + * + * See `nvtx3::domain` for more information. + * + * \section ATTRIBUTES Event Attributes + * + * NVTX events can be customized with various attributes to provide additional + * information (such as a custom message) or to control visualization of the + * event (such as the color used). These attributes can be specified per-event + * via arguments to a `nvtx3::event_attributes` object. + * + * NVTX events can be customized via four "attributes": + * - \ref COLOR : color used to visualize the event in tools. + * - \ref MESSAGES : Custom message string. + * - \ref PAYLOAD : User-defined numerical value. + * - \ref CATEGORY : Intra-domain grouping. + * + * It is possible to construct a `nvtx3::event_attributes` from any number of + * attribute objects (nvtx3::color, nvtx3::message, nvtx3::payload, + * nvtx3::category) in any order. If an attribute is not specified, a tool + * specific default value is used. See `nvtx3::event_attributes` for more + * information. + * + * \code{.cpp} + * // Set message, same as passing nvtx3::message{"message"} + * nvtx3::event_attributes attr{"message"}; + * + * // Set message and color + * nvtx3::event_attributes attr{"message", nvtx3::rgb{127, 255, 0}}; + * + * // Set message, color, payload, category + * nvtx3::event_attributes attr{"message", + * nvtx3::rgb{127, 255, 0}, + * nvtx3::payload{42}, + * nvtx3::category{1}}; + * + * // Same as above -- can use any order of arguments + * nvtx3::event_attributes attr{nvtx3::payload{42}, + * nvtx3::category{1}, + * "message", + * nvtx3::rgb{127, 255, 0}}; + * + * // Multiple arguments of the same type are allowed, but only the first is + * // used -- in this example, payload is set to 42: + * nvtx3::event_attributes attr{ nvtx3::payload{42}, nvtx3::payload{7} }; + * + * // Using the nvtx3 namespace in a local scope makes the syntax more succinct: + * using namespace nvtx3; + * event_attributes attr{"message", rgb{127, 255, 0}, payload{42}, category{1}}; + * \endcode + * + * \subsection MESSAGES message + * + * `nvtx3::message` sets the message string for an NVTX event. + * + * Example: + * \code{.cpp} + * // Create an `event_attributes` with the message "my message" + * nvtx3::event_attributes attr{nvtx3::message{"my message"}}; + * + * // strings and string literals implicitly assumed to be a `nvtx3::message` + * nvtx3::event_attributes attr{"my message"}; + * \endcode + * + * \subsubsection REGISTERED_MESSAGE Registered Messages + * + * Associating a `nvtx3::message` with an event requires copying the contents of + * the message every time the message is used, i.e., copying the entire message + * string. This may cause non-trivial overhead in performance sensitive code. + * + * To eliminate this overhead, NVTX allows registering a message string, + * yielding a "handle" that is inexpensive to copy that may be used in place of + * a message string. When visualizing the events, tools such as Nsight Systems + * will take care of mapping the message handle to its string. + * + * A message should be registered once and the handle reused throughout the rest + * of the application. This can be done by either explicitly creating static + * `nvtx3::registered_string` objects, or using the + * `nvtx3::registered_string::get` construct on first use helper (recommended). + * + * Similar to \ref DOMAINS, `nvtx3::registered_string::get` requires defining a + * custom tag type with a static `message` member whose value will be the + * contents of the registered string. + * + * Example: + * \code{.cpp} + * // Explicitly constructed, static `registered_string` in my_domain: + * static registered_string_in static_message{"my message"}; + * + * // Or use construct on first use: + * // Define a tag type with a `message` member string to register + * struct my_message{ static constexpr char const* message{ "my message" }; }; + * + * // Uses construct on first use to register the contents of + * // `my_message::message` + * auto& msg = nvtx3::registered_string_in::get(); + * \endcode + * + * \subsection COLOR color + * + * Associating a `nvtx3::color` with an event allows controlling how the event + * is visualized in a tool such as Nsight Systems. This is a convenient way to + * visually differentiate among different events. + * + * \code{.cpp} + * // Define a color via rgb color values + * nvtx3::color c{nvtx3::rgb{127, 255, 0}}; + * nvtx3::event_attributes attr{c}; + * + * // rgb color values can be passed directly to an `event_attributes` + * nvtx3::event_attributes attr1{nvtx3::rgb{127,255,0}}; + * \endcode + * + * \subsection CATEGORY category + * + * A `nvtx3::category` is simply an integer id that allows for fine-grain + * grouping of NVTX events.
