+**回答你的问题：代码数量是够的。** 15个.cu、13个prebuilt .so、qwen3_5.py已经完整引用了所有11个import。问题不是代码数量，是： + +1. **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 | +|------|------|-------------|---------| +| ex_engine/python/corex_gdn.py | GDN完整dispatch | 自己写的 | ❌ 未部署 | +| ex_engine/python/corex_moe.py |

ix_full_bridge.cpp 里明确说了 "MoE functions are NOT in base image"，所以 MoE 必须走 prebuilt .so + Python fallback 路线，而不是试图 dlopen 不存在的 ixformer MoE symbols。 + +现在的策略（13个prebuilt .so + 1个在线编译）已经是正确的路线。 diff

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. For example, one might use separate categories for + * IO, memory allocation, compute, etc. + * + * \code{.cpp} + * nvtx3::event_attributes{nvtx3::category{1}}; + * \endcode + * + * \subsubsection NAMED_CATEGORIES Named Categories + * + * Associates a `name` string with a category `id` to help differentiate among + * categories. + * + * For any given category id `Id`, a `named_category{Id, "name"}` should only + * be constructed once and reused throughout an application.
