query_register_mem_status

函数功能

在开启CacheManager的场景下，开启方式是在初始化LLMDataDist时传入llm.EnableCacheManager为1时，调用此接口查询注册内存状态。

函数原型

query_register_mem_status(comm_id: int) -> RegisterMemStatus

参数说明

调用示例

from llm_datadist import LLMDataDist, LLMRole, LlmConfig
device_id = 0
llm_datadist = LLMDataDist(LLMRole.PROMPT, 1)
options = {
    "ge.exec.deviceId": str(device_id),
    "llm.MemPoolConfig": "{\"memory_size\": 1073741824}"
}
llm_config = LlmConfig()
llm_config.enable_cache_manager = True
options.update(llm_config.generate_options())
llm_datadist.init(options)
rank_table = """
{
    "server_count": "2",
    "server_list": [
        {
            "device": [
                {
                    "device_id": "0",
                    "device_ip": "x.x.x.x",
                    "rank_id": "0"
                },
            ],
            "server_id": "x.x.x.x"
        },{
            "device": [
                {
                    "device_id": "0",
                    "device_ip": "x.x.x.x",
                    "rank_id": "0"
                },
            ],
            "server_id": "x.x.x.x"
        }
    ],
    "status": "completed",
    "version": "1.0"
}"""
comm_id = llm_datadist.link({1: 0, 2: 1}, rank_table)
print("init link suc:", comm_id)
while True:
    ret = llm_datadist.query_register_mem_status(comm_id)
    if ret == RegisterMemStatus.OK:
        print("query_register_mem_status ok", flush=True)
        break
    elif ret == RegisterMemStatus.FAILED:
        print("query_register_mem_status failed", flush=True)
        raise RuntimeError("link failed")
    print("need check again", flush=True)
    time.sleep(1)

返回值

无。

异常场景会抛出LLMException异常。

约束说明

需要开启CacheManager模式。
