herizhen ff76c6780e [releases/v0.18.0][Doc][Misc] Modifying Configuration Parameters (#8618) 
### What this PR does / why we need it?
This PR renames the environment variable VLLM_NIXL_ABORT_REQUEST_TIMEOUT
to VLLM_MOONCAKE_ABORT_REQUEST_TIMEOUT to align with the Mooncake
connector naming convention. It also updates the documentation and test
configurations to reflect this change and adjusts the suggested timeout
value in the documentation to 480 seconds for consistency.

### Does this PR introduce _any_ user-facing change?
Yes. The environment variable for configuring the abort request timeout
has been renamed. Users should update their environment settings from
VLLM_NIXL_ABORT_REQUEST_TIMEOUT to VLLM_MOONCAKE_ABORT_REQUEST_TIMEOUT.

### How was this patch tested?
The changes were verified by updating the corresponding test
configuration files and ensuring consistency across the documentation.

# DeepSeek-V3.2
## Introduction
DeepSeek-V3.2 is a sparse attention model. The main architecture is similar to DeepSeek-V3.1, but with a sparse attention mechanism, which is designed to explore and validate optimizations for training and inference efficiency in long-context scenarios.
This document will show the main verification steps of the model, including supported features, feature configuration, environment preparation, single-node and multi-node deployment, accuracy and performance evaluation.
## Supported Features
Refer to [supported features](../../user_guide/support_matrix/supported_models.md) to get the model's supported feature matrix.
Refer to [feature guide](../../user_guide/feature_guide/index.md) to get the feature's configuration.
## Environment Preparation
### Model Weight
- `DeepSeek-V3.2-Exp-W8A8`(Quantized version): require 1 Atlas 800 A3 (64G × 16) node or 2 Atlas 800 A2 (64G × 8) nodes. [Download model weight](https://www.modelscope.cn/models/vllm-ascend/DeepSeek-V3.2-Exp-W8A8)
- `DeepSeek-V3.2-w8a8`(Quantized version): require 1 Atlas 800 A3 (64G × 16) node or 2 Atlas 800 A2 (64G × 8) nodes. [Download model weight](https://www.modelscope.cn/models/vllm-ascend/DeepSeek-V3.2-W8A8/)
It is recommended to download the model weight to the shared directory of multiple nodes, such as `/root/.cache/`.
### Verify Multi-node Communication(Optional)
If you want to deploy multi-node environment, you need to verify multi-node communication according to [verify multi-node communication environment](../../installation.md#verify-multi-node-communication).
### Installation
You can use our official docker image to run `DeepSeek-V3.2` directly.
:::::{tab-set}
:sync-group: install

:::::
In addition, if you don't want to use the docker image as above, you can also build all from source:
- Install `vllm-ascend` from source, refer to [installation](../../installation.md).
If you want to deploy multi-node environment, you need to set up environment on each node.
## Deployment
:::{note}
In this tutorial, we suppose you downloaded the model weight to `/root/.cache/`. Feel free to change it to your own path.
:::
### Single-node Deployment
- Quantized model `DeepSeek-V3.2-w8a8` can be deployed on 1 Atlas 800 A3 (64G × 16).
Run the following script to execute online inference.
```shell
export HCCL_OP_EXPANSION_MODE="AIV"
export OMP_PROC_BIND=false
export OMP_NUM_THREADS=10
export VLLM_USE_V1=1
export HCCL_BUFFSIZE=200
export VLLM_ASCEND_ENABLE_MLAPO=1
export PYTORCH_NPU_ALLOC_CONF=expandable_segments:True
export VLLM_ASCEND_ENABLE_FLASHCOMM1=1
vllm serve /root/.cache/modelscope/hub/models/vllm-ascend/DeepSeek-V3.2-W8A8 \
--host 0.0.0.0 \
--port 8000 \
--data-parallel-size 2 \
--tensor-parallel-size 8 \
--quantization ascend \
--seed 1024 \
--served-model-name deepseek_v3_2 \
--enable-expert-parallel \
--max-num-seqs 16 \
--max-model-len 8192 \
--max-num-batched-tokens 4096 \
--trust-remote-code \
--no-enable-prefix-caching \
--gpu-memory-utilization 0.92 \
--compilation-config '{"cudagraph_mode": "FULL_DECODE_ONLY"}' \
--additional-config '{"layer_sharding": ["q_b_proj", "o_proj"]}' \
--speculative-config '{"num_speculative_tokens": 3, "method": "deepseek_mtp"}'
```
In PD-disaggregated deployments, `layer_sharding` is supported only on prefill/P nodes with `kv_role="kv_producer"`. Do not enable it on decode/D nodes or `kv_role="kv_both"` nodes.
### Multi-node Deployment
- `DeepSeek-V3.2-w8a8`: require at least 2 Atlas 800 A2 (64G × 8).
Run the following scripts on two nodes respectively.

### Prefill-Decode Disaggregation
We'd like to show the deployment guide of `DeepSeek-V3.2` on multi-node environment with 1P1D for better performance.
Before you start, please
1. prepare the script `launch_online_dp.py` on each node:
```python
import argparse
import multiprocessing
import os
import subprocess
import sys
def parse_args():
parser = argparse.ArgumentParser()
parser.add_argument(
"--dp-size",
type=int,
required=True,
help="Data parallel size."
)
parser.add_argument(
"--tp-size",
type=int,
default=1,
help="Tensor parallel size."
)
parser.add_argument(
"--dp-size-local",
type=int,
default=-1,
help="Local data parallel size."
)
parser.add_argument(
"--dp-rank-start",
type=int,
default=0,
help="Starting rank for data parallel."
)
parser.add_argument(
"--dp-address",

subprocess.run(command, check=True)
if __name__ == "__main__":

Once the preparation is done, you can start the server with the following command on each node:
Refer to [Distributed DP Server With Large-Scale Expert Parallelism](https://docs.vllm.ai/projects/ascend/en/latest/user_guide/feature_guide/large_scale_ep.html) to get the detailed boot method.
1. Prefill node 0
```shell
# change ip to your own
python launch_online_dp.py --dp-size 2 --tp-size 16 --dp-size-local 1 --dp-rank-start 0 --dp-address 141.61.39.105 --dp-rpc-port 12890 --vllm-start-port 9100
```
2. Prefill node 1
```shell
# change ip to your own
python launch_online_dp.py --dp-size 2 --tp-size 16 --dp-size-local 1 --dp-rank-start 1 --dp-address 141.61.39.105 --dp-rpc-port 12890 --vllm-start-port 9100
```
3. Decode node 0
```shell
# change ip to your own
python launch_online_dp.py --dp-size 8 --tp-size 4 --dp-size-local 4 --dp-rank-start 0 --dp-address 141.61.39.117 --dp-rpc-port 12777 --vllm-start-port 9100
```
4. Decode node 1
```shell
# change ip to your own
python launch_online_dp.py --dp-size 8 --tp-size 4 --dp-size-local 4 --dp-rank-start 4 --dp-address 141.61.39.117 --dp-rpc-port 12777 --vllm-start-port 9100
```
### Request Forwarding
To set up request forwarding, run the following script on any machine. You can get the proxy program in the repository's examples: [load_balance_proxy_layerwise_server_example.py](https://github.com/vllm-project/vllm-ascend/blob/main/examples/disaggregated_prefill_v1/load_balance_proxy_layerwise_server_example.py)
```shell
unset http_proxy
unset https_proxy
python load_balance_proxy_layerwise_server_example.py \
--port 8000 \
--host 141.61.39.105 \
--prefiller-hosts \
141.61.39.105 \
141.61.39.113 \
--prefiller-ports \
9100 \
9100 \
--decoder-hosts \
141.61.39.117 \
141.61.39.117 \
141.61.39.117 \
141.61.39.117 \
141.61.39.181 \
141.61.39.181 \
141.61.39.181 \
141.61.39.181 \
--decoder-ports \
9100 9101 9102 9103 \
9100 9101 9102 9103 \
```
## Functional Verification
Once your server is started, you can query the model with input prompts:
```shell
curl http://<node0_ip>:<port>/v1/completions \
-H "Content-Type: application/json" \
-d '{
"model": "deepseek_v3.2",
"prompt": "The future of AI is",
"max_completion_tokens": 50,
"temperature": 0
}'
```
## Accuracy Evaluation
Here are two accuracy evaluation methods.
### Using AISBench
1. Refer to [Using AISBench](../../developer_guide/evaluation/using_ais_bench.md) for details.
2. After execution, you can get the result.
### Using Language Model Evaluation Harness
As an example, take the `gsm8k` dataset as a test dataset, and run accuracy evaluation of `DeepSeek-V3.2-W8A8` in online mode.
1. Refer to [Using lm_eval](../../developer_guide/evaluation/using_lm_eval.md) for `lm_eval` installation.
2. Run `lm_eval` to execute the accuracy evaluation.
```shell
lm_eval \
--model local-completions \
--model_args model=/root/.cache/Eco-Tech/DeepSeek-V3.2-w8a8-mtp-QuaRot,base_url=http://127.0.0.1:8000/v1/completions,tokenized_requests=False,trust_remote_code=True \
--tasks gsm8k \
--output_path ./
```
3. After execution, you can get the result.
## Performance
### Using AISBench
Refer to [Using AISBench for performance evaluation](../../developer_guide/evaluation/using_ais_bench.md#execute-performance-evaluation) for details.
The performance result is:
**Hardware**: A3-752T, 4 node
**Deployment**: 1P1D, Prefill node: DP2+TP16, Decode Node: DP8+TP4
**Input/Output**: 64k/3k
**Performance**: 533tps, TPOT 32ms
### Using vLLM Benchmark
Run performance evaluation of `DeepSeek-V3.2-W8A8` as an example.
Refer to [vllm benchmark](https://docs.vllm.ai/en/latest/benchmarking/) for more details.
There are three `vllm bench` subcommands:
- `latency`: Benchmark the latency of a single batch of requests.
- `serve`: Benchmark the online serving throughput.
- `throughput`: Benchmark offline inference throughput.
Take the `serve` as an example. Run the code as follows.
```shell
export VLLM_USE_MODELSCOPE=true
vllm bench serve --model /root/.cache/Eco-Tech/DeepSeek-V3.2-w8a8-mtp-QuaRot --dataset-name random --random-input 200 --num-prompts 200 --request-rate 1 --save-result --result-dir ./
```
## Function Call
The function call feature is supported from v0.13.0rc1 on. Please use the latest version.
Refer to [DeepSeek-V3.2 Usage Guide](https://docs.vllm.ai/projects/recipes/en/latest/DeepSeek/DeepSeek-V3_2.html#tool-calling-example) for details.
