What this PR does / why we need it?

The basic configs are extracted and reused for eplb UT. This is done so that if the basic configs are changed later, eplb UT does not need to be modified repeatedly.

Does this PR introduce any user-facing change?

How was this patch tested?

Summary of Changes

Hello @Spicy-Stick, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on improving the maintainability and coverage of end-to-end tests for models leveraging Expert Parallel Load Balancing (EPLB). It achieves this by centralizing shared test configurations, thereby reducing code duplication and making test setups more consistent. Additionally, new test scenarios are introduced for specific models and operational modes, enhancing the robustness of the testing framework for EPLB functionalities.

Highlights

Test Configuration Refactoring: Common test setup variables such as port, env_dict, speculative_config, additional_config, compilation_config, and server_args have been moved from within test functions to module-level scope in test_deepseek_r1_0528_w8a8.py and test_qwen3_235b_w8a8.py. This promotes reusability and reduces redundancy across related test cases.
EPLB Test Enhancement for DeepSeek Model: The test_deepseek_r1_0528_w8a8_eplb.py file has been refactored to import shared configurations from test_deepseek_r1_0528_w8a8.py. It now supports different execution modes (e.g., 'single') and includes a specific eplb_policy: 3 in its eplb_config.
New EPLB Test Case for Qwen3 Model: A new comprehensive test case has been added to test_qwen3_235b_a22b_w8a8_eplb.py for the Qwen3 235B A22B model. This test also imports common configurations and dynamically adjusts compilation_config based on the test mode (e.g., 'piecewise').

Code Review

The code changes involve modifications to several test files, including moving the definitions of port, env_dict, and server_args outside the test_models function in test_deepseek_r1_0528_w8a8.py and test_qwen3_235b_w8a8.py. The test_deepseek_r1_0528_w8a8_eplb.py file was refactored to import configurations from test_deepseek_r1_0528_w8a8.py and update the additional configuration with EPLB settings. Similarly, test_qwen3_235b_a22b_w8a8_eplb.py was modified to import configurations from test_qwen3_235b_w8a8.py and extend server arguments with additional configurations. A review comment pointed out that the added block of code introduces a second test_models function definition, which will overwrite the existing one, and suggested removing the old test_models function and its related configurations.

This added block of code introduces a second test_models function definition in the file, which will overwrite the existing one (lines 52-105). This appears to be an incomplete refactoring. The old test_models function and its related configurations should be removed to avoid confusion and potential conflicts.

Let me start by recalling what I know about deep learning. It's a subset of machine learning, right? So first, I should mention that it's part of machine learning, which itself is a branch of AI. Then, the key aspect of deep learning is the use of neural networks with multiple layers. These are called deep neural networks.\n\nWait, I should define neural networks first. Maybe start with the basics. A neural network is inspired by the human brain, with layers of nodes (neurons) that process data. But deep learning specifically refers to networks with many layers—hence \"deep.\" So the term \"deep\" comes from the number of layers. \n\nI should explain how deep learning works. It involves training these networks on large datasets, allowing them to automatically learn features from the data. Unlike traditional machine learning, where you might have to manually extract features, deep learning models can do this automatically. That's a key point. For example, in image recognition, a deep learning model can learn to detect edges, shapes, and then more complex patterns without human intervention.\n\nApplications are important too. The user might want to know where deep learning is used. Common examples include image and speech recognition, natural language processing, autonomous vehicles, and recommendation systems. Maybe mention specific technologies like self-driving cars using computer vision or virtual assistants like Siri or Alexa - vLLM version: v0.15.0 - vLLM main: https://github.com/vllm-project/vllm/commit/13397841ab469cecf1ed425c3f52a9ffc38139b5 Signed-off-by: shenchuxiaofugui <1311027364@qq.com> [Bugfix] Fix wrong computed_tokens when meet exception. (#6522)   Fix wrong computed_tokens when meet exception. This pull request addresses a bug in the KV transfer mechanism where an exception during token lookup operations could lead to an incorrect count of computed_tokens. By modifying the exception handling in both the lookup and lookup_scheduler functions to return 0 instead of the start index, the system now correctly indicates that no tokens were successfully processed when a remote connection failure occurs. This enhancement improves the robustness and accuracy of token management within the vllm_ascend distributed KV pool.  NO.

Following https://github.com/vllm-project/vllm/pull/32322, use the `memory_profiling` context manager from vllm for profiling. 2. Fix wrong non-torch memory value recorded during profiling, which is not its peak during inference. --- **More details about point 2:** After profling, the non-torch memory value we recorded is lower than that in real inference. This is mainly because of the different memory management behaviour between `torch.cuda.empty_cache()` and `torch.npu.empty_cache()`. With regard to `torch.cuda.empty_cache()`, it only recycle the unused memory in pytorch memory pool (i.e., memory managed by pytorch caching allocator), **with no affect to non-torch memory**. However, as for `torch.npu.empty_cache()`, it has a totally different memory management mechanism, i.e., it may call `aclrtSynchronize` and **enable Ascend runtime to free up non-torch memory**. Thus, the non-torch memory value we recorded after `torch.npu.empty_cache()` is much lower than its peak during profling. Resolution: We record the peak non-torch memory value (`non_torch_memory_before_empty_cache`) after profiling, but before `torch.npu.empty_cache()`. Then, we add the diff (`non_torch_memory_cleared_by_empty_cache = non_torch_memory_before_empty_cache - self.non_torch_memory`) to non-torch memory when calculating available KV cache memory, which will lead to less KV cache memory (i.e., it's safer to avoid OOM issues). --- > [!NOTE] > This PR needs to wait for main2main aligning to latest vllm commit before merging. no. Before this PR, the non-torch memory we used to calculate available KV cache memory is **0.90 G**, whereas its peak during real inference is **1.08 G**, diff: **182.00 M**. After this PR, we add this diff to non-torch memory after profiling and thus make the profiling results more accurate. - vLLM version: v0.15.0 - vLLM main: https://github.com/vllm-project/vllm/commit/d7e17aaacd5ed1b4b4be6bcfef3a1b7cbc84fc9a --------- Signed-off-by: shen-shanshan <467638484@qq.com> [Bugfix] Add the missing parentheses to @torch.inference_mode (#6757) This PR fixes a bug in `vllm_ascend/worker/model_runner_v1.py` where the `@torch.inference_mode` decorator was used without parentheses.

We can see from the profiling results below, before the real computation of Attention, there are long free time in the device, which will lead to extremely low NPU utilization. <img width="2264" height="1398" alt="iShot_2026-01-23_16 26 39" src="https://github.com/user-attachments/assets/37f21d06-e526-4f28-82fe-005746cf13bd" /> --- **To opitimize this, this PR has proposed four changes:** 1. Use `seq_lens` CPU cache to avoid frequent d2h copy. Before this PR, `AscendMMEncoderAttention` will copy the `cu_seqlens` from NPU to CPU in every forward, since the op `_npu_flash_attention_unpad()` requires CPU `cu_seqlens` (otherwise it will crash). Thus, we use `seq_lens_cpu_cache` to cache this tensor, since it's shared between all layers, but may change in different forward step. When the current `layer_index` is `0`, we update the cache, otherwise we directly use the cache to avoid frequent `diff` and `copy` operations, which are costful. 2. Pre-compute the scale value to avoid calculating it in every forward. 3. Move the judgment of `enable_pad` from forward to the `__init__` method. 4.

As a result, the total_num_scheduled_tokens obtained by decode nodes from the scheduler lacks spec tokens. When determining whether to enqueue the full graph on decode nodes, the condition for uniform_decode ` scheduler_output.total_num_scheduled_tokens == self.input_batch.num_reqs * max_query_len` is not met, leading to the current instance not being enqueued into the full graph. The above situation leads to both full graph and eagle mode instances coexisting in the decode instances. Due to the synchronization wait of MoeDispatch, the decode instances in full graph are significantly slowed down by the instance in eagle mode. **Solution** The scenario is PD separation + MTP + Full Graph + asynchronous scheduling. On the decode nodes, the spec tokens of the request with KV cache from P need be padded. Then, the padded spec tokens will be rejected by sampling. This operation ensures that the uniform_decode condition is satisfied when determining whether decode nodes are included in the full graph, thereby guaranteeing that all decode instances are present in the full graph and avoiding synchronous waiting for MoeDispatch. - vLLM version: v0.15.0 - vLLM main: https://github.com/vllm-project/vllm/commit/5326c89803566a131c928f7fdd2100b75c981a42 Signed-off-by: chenmenglong <chenmenglong1@huawei.com> [Doc][Release] Add release note skill (#6824) This PR adds the releaseing note skills: - `SKILL.md`: vLLM Ascend Releasing Note Writer - `references/ref-past-release-notes-highlight.md`: And also add a `output/v0.13.0` examples which was used by https://github.com/vllm-project/vllm-ascend/commit/2da476d82f048816095794a9c0ac45126dc251af Inspired: https://github.com/simon-mo/release-notes-writing/ No - vLLM version: v0.15.0 - vLLM main: https://github.com/vllm-project/vllm/commit/83b47f67b1dfad505606070ae4d9f83e50ad4ebd Co-authored-by: esmeetu <jasonailu87@gmail.com> --------- Signed-off-by: Yikun Jiang <yikunkero@gmail.com> [Feat]support sequence parallelism by pass for VL models (#5632) [CI] Fix doc test fail when load model with error information: 'Stale file handle' (#6832) This PR fixes a `Stale file handle` error that occurs during doctests in the CI environment.

As a result, the total_num_scheduled_tokens obtained by decode nodes from the scheduler lacks spec tokens. When determining whether to enqueue the full graph on decode nodes, the condition for uniform_decode ` scheduler_output.total_num_scheduled_tokens == self.input_batch.num_reqs * max_query_len` is not met, leading to the current instance not being enqueued into the full graph. The above situation leads to both full graph and eagle mode instances coexisting in the decode instances. Due to the synchronization wait of MoeDispatch, the decode instances in full graph are significantly slowed down by the instance in eagle mode. **Solution** The scenario is PD separation + MTP + Full Graph + asynchronous scheduling. On the decode nodes, the spec tokens of the request with KV cache from P need be padded. Then, the padded spec tokens will be rejected by sampling. This operation ensures that the uniform_decode condition is satisfied when determining whether decode nodes are included in the full graph, thereby guaranteeing that all decode instances are present in the full graph and avoiding synchronous waiting for MoeDispatch. - vLLM version: v0.15.0 - vLLM main: https://github.com/vllm-project/vllm/commit/5326c89803566a131c928f7fdd2100b75c981a42 Signed-off-by: chenmenglong <chenmenglong1@huawei.com> [Doc][Release] Add release note skill (#6824) This PR adds the releaseing note skills: - `SKILL.md`: vLLM Ascend Releasing Note Writer - `references/ref-past-release-notes-highlight.md`: And also add a `output/v0.13.0` examples which was used by https://github.com/vllm-project/vllm-ascend/commit/2da476d82f048816095794a9c0ac45126dc251af Inspired: https://github.com/simon-mo/release-notes-writing/ No - vLLM version: v0.15.0 - vLLM main: https://github.com/vllm-project/vllm/commit/83b47f67b1dfad505606070ae4d9f83e50ad4ebd Co-authored-by: esmeetu <jasonailu87@gmail.com> --------- Signed-off-by: Yikun Jiang <yikunkero@gmail.com> [Feat]support sequence parallelism by pass for VL models (#5632) [CI] Fix doc test fail when load model with error information: 'Stale file handle' (#6832) This PR fixes a `Stale file handle` error that occurs during doctests in the CI environment. The error appears when loading models from ModelScope, likely due to issues with network file systems used in CI. The fix involves setting the `MODELSCOPE_HUB_FILE_LOCK` environment variable to `false` in the `run_doctests.sh` script. This disables file locking in the ModelScope hub, which is a common workaround for this type of file system error. No, this change only affects the CI test execution environment and has no impact on users. This change is validated by the CI pipeline. A successful run of the doctests indicates that the fix is effective.
