Npugraph_ex

Introduction

As introduced in the RFC, this is a simple ACLGraph graph mode acceleration solution based on Fx graphs.

Using Npugraph_ex

Npugraph_ex will be enabled by default in the future, Take Qwen series models as an example to show how to configure it.

Offline example:

from vllm import LLM

model = LLM(
    model="path/to/Qwen2-7B-Instruct",
    additional_config={
        "ascend_compilation_config": {
            "enable_npugraph_ex": True,
            "enable_static_kernel": False,
        }
    }
)
outputs = model.generate("Hello, how are you?")

Online example:

vllm serve Qwen/Qwen2-7B-Instruct
--additional-config '{"ascend_compilation_config":{"enable_npugraph_ex":true, "enable_static_kernel":false}}'
