a63dd5868d [0.18.0][cherry-pick][BugFix]Fix compilation errors for operators dispatch_gmm_combine_decode/moe_combine_normal/moe_dispatch_normal (#7844)
**What this PR does / why we need it?**
pick from https://github.com/vllm-project/vllm-ascend/pull/7114

Fix compilation errors encountered when building versions later than
b020 for the following operators:
dispatch_gmm_combine_decode, moe_combine_normal, moe_dispatch_normal
**Root Cause**
After the b020 version update, the original moe_distribute_base.h file
was updated and its definitions changed, which caused compilation
failures for the above three operators that depend on this file.
**Solution**
We have added a dedicated copy of moe_distribute_base.h into the
implementation of these three operators, ensuring stable compilation
independent of framework version updates.

**Does this PR introduce any user-facing change?**
No. There are no user-facing changes; this fix only resolves compilation
issues without affecting functionality or user behavior.

**How was this patch tested?**
vLLM version: releases/v0.18.0

5f3826b093 [Build] Add support for Ascend950 chip (#7151)
### What this PR does / why we need it?
This PR adds support for the Ascend950 chip. This includes:
- Updating build scripts (`CMakeLists.txt` and `setup.py`) to recognize
the Ascend950 chip and set appropriate compilation flags.
- Disabling a set of custom operators that are not yet supported on the
Ascend950 hardware target.
- Performing a codebase-wide refactoring of `pipe_barrier()` calls to
the namespaced `AscendC::PipeBarrier<>()` for improved code consistency
and adherence to the latest API standards.

Ascend950DT e2e passed (Qwen3-32B-MXFP8) and CI passed

f71812011d [Feature] DispatchGmmCombineDecode support bf16/float16 gmm1/gmm2 weight and support gmm weight with ND format (#6393)
### What this PR does / why we need it?
1. support ND format gmm weight input.
Before this pr, gmm1_weight and gmm2_weight could only be passed as
input to the DispatchGmmCombineDecode operator in NZ data format. After
the modification, they are allowed to be passed in ND data format.
2. support bf16/float16 gmm weight
The current PR modification enables the DispatchGmmCombineDecode
operator to support non-W8A8 scenarios, allowing gmm1_weight and
gmm2_weight to be passed as float16/bfloat16 which is correspond with
input token data type.

ebb940691f [Feature] Adapt DispathGmmCombineDecode opertor to align with weight scale dtype of small operators. [RFC: issue 5476] (#5755)
### What this PR does / why we need it?

[Feature] Adapt DispathGmmCombineDecode opertor to align with weight
scale dtype of small operators.
- **Before**: weight scale must be float32
- **After**: weight scale can be float32/float16 when x is float16,
float32/bfloat16 when x is float32/bfloat16. And w1 scale can use
different dtype with w2 scale.

More info about this operator, please refer to RFC: issue
https://github.com/vllm-project/vllm-ascend/issues/5476

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

### How was this patch tested?
#### Perf

> When scale is of type fp16 or bf16, it will be cast to fp32 internally
within the operator, while the subsequent computations remain unchanged.
Therefore, this PR will introduce an additional cast operation but halve
the memory copy operations for scale . Furthermore, since the scale data
is only a few KB in size and participates in relatively few
computations, its impact is almost negligible compared to major
operations like matrix multiplication. Thus, the theoretical performance
change should be minimal.

test single operator cases from qwen3-235b,
- single A3 node(ep16), 64 moe experts, 4 experts / die (like qwen3-235b
ep32)
- batch=18/32, token_hidden_size 4096, moe_intermediate_size 1536

The test was conducted for 100 rounds, and the average of the last 95
rounds was taken.

Note: Single-operator benchmarks represent an ideal scenario. They are
usually only useful for referencing relative changes and may not fully
align with performance data observed within the full model.

e67608041d [main][BugFix]Fix DispatchGmmCombineDecode acc bug when big batch (#5808)
### What this PR does / why we need it?
If one expert handle more than 48 * 8 token, DispatchGmmCombineDecode
may incur acc problem, because a flag is set too early.

> Reason: LocalTensor ubInputRightHalf, ubInputTmp, ubInputRightHalf,
ubQuantF32, ubQuantS32, and ubQuantF16 use the same space with ubAbs, so
only after all of them are free, the copy from gm into ubInputRightHalf
can start, while before this pr,
AscendC::SetFlag<AscendC::HardEvent::V_MTE2>(0) is too early.

This pr sets flag at right time.

bd8be2e759 [Kernel] Add moe normal ops (#4810)
### What this PR does / why we need it?
1.Add the implementation of normal Aclnn operators: MoeCombineNormal,
MoeDispatchNormal, NotifyDispatch,and DispatchLayout.

- MoeCombineNormal: Implements the combine logic within MoE operations.
- MoeDispatchNormal: Implements the dispatch logic within MoE
operations.
- NotifyDispatch: Exchanges topk_idx information among different ranks
to calculate the device memory required for the dispatch stage.
- DispatchLayout: Used to calculate information related to the device
memory layout for the dispatch stage.

2.Provide PyTorch interfaces for normal operators—get_dispatch_layout,
dispatch_prefill, and combine_prefill—to be used for MoE communication
during the prefill stage in vLLM.

- get_dispatch_layout: Calculates information related to the device
memory layout for the dispatch operator, and is called before
dispatch_prefill.
- dispatch_prefill: Initiates the dispatch operation.
- combine_prefill: Initiates the combine operation.

### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
The functionality has already been validated using the local Qwen model.
Test cases will be added after support for multi-NPU use cases in the CI
pipeline is finalized.

9567e5dd8c [kernel] Adapt DispatchGmmCombineDecode operator to parameters of small operators (#4790)
### What this PR does / why we need it?

This PR adapt DispatchGmmCombineDecode operator to parameters of small
operators.
1. This operator no longer requires permuting the weights and scales of
GMM1.
2. This operator no longer requires transposing the weights of GMM2.

Therefore, this operator and the small operator can use the same
parameters (weights and scales), which is beneficial for model
adaptation.
