GLM-5/GLM-5.1#

Introduction#

This document applies to both GLM-5 and GLM-5.1. Unless otherwise specified, all descriptions, configurations, and deployment procedures for GLM-5 in this document also apply to GLM-5.1. For brevity, GLM-5 is used hereafter as a unified reference to both GLM-5 and GLM-5.1.

GLM-5 use a Mixture-of-Experts (MoE) architecture and targets complex systems engineering and long-horizon agentic tasks.

The GLM-5 model is first supported in vllm-ascend:v0.17.0rc1. The version of transformers need to be upgraded to 5.2.0.

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 to get the model’s supported feature matrix.

Refer to feature guide to get the feature’s configuration.

Environment Preparation#

Model Weight#

It is recommended to download the model weight to the shared directory of multiple nodes, such as /root/.cache/

Installation#

You can use our official docker image to run GLM-5 directly.

Start the docker image on your each node.

export IMAGE=quay.io/ascend/vllm-ascend:v0.20.2rc1-a3
export NAME=vllm-ascend

In addition, if you don’t want to use the docker image as above, you can also build all from source:

If you want to deploy multi-node environment, you need to set up environment on each node.

    To support a 200k context window on the stage of prefill, the parameter "layer_sharding": ["q_b_proj"] needs to be added to --additional_config on each prefill node.

Once the preparation is done, you can start the server with the following command on each node:

  1. Prefill node 0

    # 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 $node_p0_ip --dp-rpc-port 10521 --vllm-start-port 6700
    
  2. Prefill node 1

    # 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 $node_p0_ip --dp-rpc-port 10521 --vllm-start-port 6700
    
  3. Decode node 0

    # change ip to your own
    python launch_online_dp.py --dp-size 16 --tp-size 4 --dp-size-local 4 --dp-rank-start 0 --dp-address $node_d0_ip --dp-rpc-port 10523 --vllm-start-port 6721
    
  4. Decode node 1

    # change ip to your own
    python launch_online_dp.py --dp-size 16 --tp-size 4 --dp-size-local 4 --dp-rank-start 4 --dp-address $node_d0_ip --dp-rpc-port 10523 --vllm-start-port 6721
    
  5. Decode node 2

    # change ip to your own
    python launch_online_dp.py --dp-size 16 --tp-size 4 --dp-size-local 4 --dp-rank-start 8 --dp-address $node_d0_ip --dp-rpc-port 10523 --vllm-start-port 6721
    
  6. Decode node 3

    # change ip to your own
    python launch_online_dp.py --dp-size 16 --tp-size 4 --dp-size-local 4 --dp-rank-start 12 --dp-address $node_d0_ip --dp-rpc-port 10523 --vllm-start-port 6721
    

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_server_example.py

unset http_proxy
unset https_proxy

python load_balance_proxy_server_example.py \
    --port 8000 \
    --host 0.0.0.0 \
    --prefiller-hosts \
       $node_p0_ip \
       $node_p1_ip \
    --prefiller-ports \
       6700 \

      6721 6722 6723 6724 \
      6721 6722 6723 6724      

Notice:

Some configurations for optimization are shown below:

  • VLLM_ASCEND_ENABLE_FLASHCOMM1: Enable FlashComm optimization to reduce communication and computation overhead on prefill node. With FlashComm enabled, layer_sharding list cannot include o_proj as an element.

  • VLLM_ASCEND_ENABLE_FUSED_MC2: Enable following fused operators: dispatch_gmm_combine_decode and dispatch_ffn_combine operator.

  • VLLM_ASCEND_ENABLE_MLAPO: Enable fused operator MlaPreprocessOperation.

Please refer to the following python file for further explanation and restrictions of the environment variables above: envs.py

Functional Verification#

Once your server is started, you can query the model with input prompts:

curl http://<node0_ip>:<port>/v1/completions \
    -H "Content-Type: application/json" \
    -d '{
        "model": "glm-5",
        "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 for details.

  2. After execution, you can get the result.

Using Language Model Evaluation Harness#

Not tested yet.

Performance#

Using AISBench#

Refer to Using AISBench for performance evaluation for details.

Using vLLM Benchmark#

Refer to vllm benchmark for more details.

Best Practices#

In this chapter, we recommend best practices in prefill-decode disaggregation scenario with 1P1D architecture using 4 Atlas 800 A3 (64G × 16):

  • Low-latency: We recommend setting dp4 tp8 on prefill nodes and dp4 tp8 on decode nodes for low latency situation.

  • High-throughput: dp4 tp8 on prefill nodes and dp8 tp4 on decode nodes is recommended for high throughput situation.

Notice: max-model-len and max-num-seqs need to be set according to the actual usage scenario. For other settings, please refer to the Deployment chapter.

FAQ#
