129ba9fe1b [BugFix] Fix Smoke Testing Bug for DSR1 longseq (#5613)
### What this PR does / why we need it?
Fix Smoke Testing Bug for DSR1 longseq
We need to make this change because the daily smoke test case is
throwing an error: "max_tokens or max_completion_tokens is too large:
32768.This model's maximum context length is 32768 tokens and your
request has 128 input tokens". We encounter this error due to
max-out-len equals to max-model-len. We can fix this error by increasing
max-model-len argument in the script.

rejection_random_sample_kernel delivering superior performance compared
to the existing Triton implementations. The new Triton kernels maintain
full functional accuracy while delivering significant performance
improvements across various batch sizes and MTP configurations.

### Does this PR introduce _any_ user-facing change?

Yes, this PR modifies rejection_sampler.py to use optimized Triton
kernels:
rejection_random_sample_kernel is modified and optimized

### How was this patch tested?

f5af6bbd1e [CI] Add qwen-235b-a22b a2 multi-node test (#5393)
### What this PR does / why we need it?
Qwen3-235B-A22B belongs to the TopN model, but there is currently a lack
of care for the test cases of the wen3-235B-A22B model on Atlas A2, and
most of the machines currently owned by users in the community are A2.
When users encounter problems, we currently have no way of knowing
whether the model runs normally on the corresponding version of the
code, so we added it. In addition, we currently see TopN models such as:
qwen-dense, qwen3-30b-a3b, Qwen3-Next, Qwen2.5-Omni, but Qwen3-235B-A22B
is missing.

### Does this PR introduce _any_ user-facing change?
NA

### How was this patch tested?
Test with multi-node, result as following:
1. Accuracy test (Time for executing this test case: 25 minutes)
test running successfully, accuracy as following:

c2f776b846 [Nightly] Initial logging for nightly multi-node testing (#5362)
### What this PR does / why we need it?
Currently, our multi-node logs only show the master node's logs (via the
Kubernetes API), which is insufficient for effective problem
localization if other nodes experience issues. Therefore, this pull
request adds the ability to upload logs for other nodes.

Next plan: Output structured directory logs, including logs from each
node and the polog.

7372225bcb [FIX] Update _causal_conv1d_update_kernel for Efficient Conv State Handling on NPU (#5322)
Description:

This PR updates the implementation of the Triton operator for deployment
on NPU devices, focusing on optimizing grid size and memory handling
based on NPU limitations.

Design Plan:

Grid Calculation: The grid size is now dynamically calculated by batch
and dim to ensure that the number of programs executed does not exceed
the NPU's vector core capacity. This ensures optimal parallelism without
overloading the hardware.

Data Block Handling: Due to the limited on-chip memory (UB) on Ascend
NPUs, this implementation splits large data into smaller chunks of 32k
or less per block. The kernel performs a for-loop to process the data in
these smaller chunks, minimizing memory usage and avoiding potential
overflows.

Changes Compared to GPU Implementation:

Grid and Block Sizing:

For GPU, the grid and block size were determined based on available
thread counts and memory size. In contrast, the NPU version dynamically
adjusts these parameters using B_TILE and BLOCK_N to optimize for NPU’s
architecture.

Memory Chunking:

The original GPU implementation did not require chunking due to the
higher available memory and processing capacity. For the NPU, data is
divided into smaller chunks (32k or smaller) to comply with memory
constraints on the device. The kernel has been modified to handle this
chunking mechanism inside a loop.

Optimized Thread Usage:

The NPU implementation takes into account the hardware-specific thread
limit (24 threads per vector core), ensuring that the number of active
programs is aligned with the NPU's vector core count, avoiding
over-subscription that would lead to serial processing.

This PR ensures that the operator functions efficiently on Ascend NPU,
considering hardware limitations while maintaining the same
functionality and input parameters as the GPU implementation.

6d25372baa Add MagicMTP(block verify) and Triton optimization (#4443)
### What this PR does / why we need it?
1. MagicMTP (paper: "Block Verification Accelerates Speculative
Decoding") was introduced to consider the influence among multiple draft
tokens, improving the acceptance rate without compromising accuracy.
2. The rejection sampling logic in rejection_sampler.py was restructured
using Triton-Ascend, enabling it to operate under high concurrency, thus
resolving CPU and NPU operator bottlenecks and enhancing throughput.

### Does this PR introduce _any_ user-facing change?
MagicMTP will automatically take effect when the parameter
"num_speculative_tokens" >= 3.

Therefore, this operator and the small operator can use the same

adaptation.
