From 0cdf98ac48cd97e09a3d77be1edae5d253c8763f Mon Sep 17 00:00:00 2001 From: lty Date: Fri, 12 Dec 2025 16:56:18 +0800 Subject: [PATCH] [usability]Modify the default value of the protocol to ascend (#4959) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ### What this PR does / why we need it? The recommended configuration in the document kv_pool.md is ascend. Modify the default value of the protocol to ascend，Improve usability #### 1.Configure mooncake.json The environment variable **MOONCAKE_CONFIG_PATH** is configured to the full path where mooncake.json is located. ``` { "local_hostname": "xx.xx.xx.xx", "metadata_server": "P2PHANDSHAKE", "protocol": "ascend", "device_name": "", "alloc_in_same_node": true, "master_server_address": "xx.xx.xx.xx:50088", "global_segment_size": "1GB" (1024MB/1048576KB/1073741824B/1073741824) } ``` **local_hostname**: Configured as the IP address of the current master node. **metadata_server**: Configured as **P2PHANDSHAKE**. **protocol:** Configured for Ascend to use Mooncake's HCCL communication. **device_name**: "" **alloc_in_same_node**: Indicator for preferring local buffer allocation strategy. **master_server_address**: Configured with the IP and port of the master service. **global_segment_size**: Expands the kvcache size registered by the PD node to the master. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Mooncake does not set up a protocol to launch the pooled VLLM service; test whether the pooling function is working.
