+# Long-Sequence Context Parallel (Deepseek)
+
+## Getting Start
+
+vLLM-Ascend now supports long sequence with context parallel options. This guide takes one-by-one steps to verify these features with constrained resources.
+
+Take the Deepseek-V3.1-w8a8 model as an example, use 3 Atlas 800T A3 servers to deploy the “1P1D” architecture. Node p is deployed across multiple machines, while node d is deployed on a single machine. Assume the ip of the prefiller server is 192.0.0.1 (prefill 1) and 192.0.0.2 (prefill 2), and the decoder servers are 192.0.0.3 (decoder 1). On each server, use 8 NPUs 16 chips to deploy one service instance.In the current example, we will enable the context parallel feature on node p to improve TTFT. Although enabling the DCP feature on node d can reduce memory usage, it would introduce additional communication and small operator overhead. Therefore, we will not enable the DCP feature on node d.
+
+## Environment Preparation
+
+### Model Weight
+
+- `DeepSeek-V3.1_w8a8mix_mtp`(Quantized version with mix mtp): [Download model weight](https://www.modelscope.cn/models/Eco-Tech/DeepSeek-V3.1-w8a8). Please modify `torch_dtype` from `float16` to `bfloat16` in `config.json`.
+
+It is recommended to download the model weight to the shared directory of multiple nodes, such as `/root/.cache/`
+
+### Verify Multi-node Communication
+
+Refer to [verify multi-node communication environment](../installation.md#verify-multi-node-communication) to verify multi-node communication.
+
+### Installation
+
+You can using our official docker image to run `DeepSeek-V3.1` directly.
+
+Select an image based on your machine type and start the docker image on your node, refer to [using docker](../installation.md#set-up-using-docker).
+
+```{code-block} bash
+   :substitutions:
+# Update --device according to your device (Atlas A2: /dev/davinci[0-7] Atlas A3:/dev/davinci[0-15]).
+# Update the vllm-ascend image according to your environment.
+# Note you should download the weight to /root/.cache in advance.
+# Update the vllm-ascend image
+export IMAGE=m.daocloud.io/quay.io/ascend/vllm-ascend:|vllm_ascend_version|
+export NAME=vllm-ascend
+
+# Run the container using the defined variables
+# Note: If you are running bridge network with docker, please expose available ports for multiple nodes communication in advance

+```
+
+You need to set up environment on each node.
+
+## Prefiller/Decoder Deployment
+
+We can run the following scripts to launch a server on the prefiller/decoder node, respectively. Please note that each P/D node will occupy ports ranging from kv_port to kv_port + num_chips to initialize socket listeners. To avoid any issues, port conflicts should be prevented. Additionally, ensure that each node's engine_id is uniquely assigned to avoid conflicts.
+
+1. Run the following script to execute online 128k inference on three nodes respectively.

+
+```shell
+cd vllm-ascend/examples/disaggregated_prefill_v1/
+bash proxy.sh
+```
+
+**Notice:**
+The parameters are explained as follows:
+- `--tensor-parallel-size` 16 are common settings for tensor parallelism (TP) sizes.
+- `--prefill-context-parallel-size` 2 are common settings for prefill context parallelism (PCP) sizes.
+- `--decode-context-parallel-size` 8 are common settings for decode context parallelism (DCP) sizes.
+- `--max-model-len` represents the context length, which is the maximum value of the input plus output for a single request.
+- `--max-num-seqs` indicates the maximum number of requests that each DP group is allowed to process. If the number of requests sent to the service exceeds this limit, the excess requests will remain in a waiting state and will not be scheduled. Note that the time spent in the waiting state is also counted in metrics such as TTFT and TPOT. Therefore, when testing performance, it is generally recommended that `--max-num-seqs` * `--data-parallel-size` >= the actual total concurrency.
+- `--max-num-batched-tokens` represents the maximum number of tokens that the model can process in a single step. Currently, vLLM v1 scheduling enables ChunkPrefill/SplitFuse by default, which means:
+  - (1) If the input length of a request is greater than `--max-num-batched-tokens`, it will be divided into multiple rounds of computation according to `--max-num-batched-tokens`;
+  - (2) Decode requests are prioritized for scheduling, and prefill requests are scheduled only if there is available capacity.
+  - Generally, if `--max-num-batched-tokens` is set to a larger value, the overall latency will be lower, but the pressure on GPU memory (activation value usage) will be greater.
+- `--gpu-memory-utilization` represents the proportion of HBM that vLLM will use for actual inference. Its essential function is to calculate the available kv_cache size. During the warm-up phase (referred to as profile run in vLLM), vLLM records the peak GPU memory usage during an inference process with an input size of `--max-num-batched-tokens`. The available kv_cache size is then calculated as: `--gpu-memory-utilization` * HBM size - peak GPU memory usage. Therefore, the larger the value of `--gpu-memory-utilization`, the more kv_cache can be used. However, since the GPU memory usage during the warm-up phase may differ from that during actual inference (e.g., due to uneven EP load), setting `--gpu-memory-utilization` too high may lead to OOM (Out of Memory) issues during actual inference. The default value is `0.9`.
+- `--enable-expert-parallel` indicates that EP is enabled. Note that vLLM does not support a mixed approach of ETP and EP; that is, MoE can either use pure EP or pure TP.
+- `--no-enable-prefix-caching` indicates that prefix caching is disabled. To enable it, remove this option.
+- `--quantization` "ascend" indicates that quantization is used. To disable quantization, remove this option.
+- `--compilation-config` contains configurations related to the aclgraph graph mode. The most significant configurations are "cudagraph_mode" and "cudagraph_capture_sizes", which have the following meanings:
+"cudagraph_mode": represents the specific graph mode. Currently, "PIECEWISE" and "FULL_DECODE_ONLY" are supported. The graph mode is mainly used to reduce the cost of operator dispatch. Currently, "FULL_DECODE_ONLY" is recommended.
+- "cudagraph_capture_sizes": represents different levels of graph modes. The default value is [1, 2, 4, 8, 16, 24, 32, 40,..., `--max-num-seqs`]. In the graph mode, the input for graphs at different levels is fixed, and inputs between levels are automatically padded to the next level. Currently, the default setting is recommended. Only in some scenarios is it necessary to set this separately to achieve optimal performance.
+- `export VLLM_ASCEND_ENABLE_FLASHCOMM1=1` indicates that Flashcomm1 optimization is enabled. Currently, this optimization is only supported for MoE in scenarios where tensor-parallel-size > 1.
+
+**Notice:**
+- tensor-parallel-size needs to be divisible by decode-context-parallel-size.
+- decode-context-parallel-size must less than or equal to tensor-parallel-size.

+## 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, here is the result of `DeepSeek-V3.1-w8a8` in `vllm-ascend:0.12.0rc1` for reference only.
+
+| dataset  | version | metric | mode | ttft |
+|----------| ----- | ----- | ----- |-----------------------|

+
+## Performance
+
+### Using AISBench
+
+Refer to [Using AISBench for performance evaluation](../developer_guide/evaluation/using_ais_bench.md#execute-performance-evaluation) for details.
+
+### Using vLLM Benchmark
+
+Run performance evaluation of `DeepSeek-V3.1-w8a8` as an example.
+
+Refer to [vllm benchmark](https://docs.vllm.ai/en/latest/contributing/benchmarks.html) for more details.
+
+There are three `vllm bench` subcommand:
+- `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 /path_to_weight/DeepSeek-V3.1_w8a8mix_mtp  --dataset-name random --random-input 131072 --num-prompt 20 --request-rate 0 --save-result --result-dir ./
+```
+
+After about several minutes, you can get the performance evaluation result.
