However, RDMA Test fails with "ERROR: RDMA traffic test FAILED: Please check ERROR: a) physical switch port configuration for Priority Flow Control. ERROR: b) job owner has write permission at 192.168.206.51 \C$" for the following scenarios: From pSMBNIC1 of N1 to pSMBNIC...
perftest是RDMA性能测试工具,该工具由开源社区维护并发布。针对RDMA的5种操作类型:Send、RDMA Read、RDMA Write、RDMA Atomic、Native Ethernet进行带宽和时延测试。 一、RDMA简介 在进行perftest测试之前需要对RDMA做一些基本的了解: RDMA (Remote Direct Memroy Access )为了消除传统网络通信带给计算任务的瓶颈,利用 Ke...
训练大模型,节点间通信成本很高,InfiniBand与GPU的组合可以提供跨节点的 GPUDirect RDMA,就是说两个节点的GPU通信不需要经过内存和CPU,而是直接由InfiniBand网卡通信。GPUDirect RDMA对于大模型训练尤其重要,因为模型都在GPU上,模型拷贝到CPU上就已经耗费了大量时间,再通过CPU发送至其他节点就更慢了。
preftest(Performance Test)是一组基于uverbs编写的测试工具集,旨在用作性能微基准。这些测试可以用作硬件或软件调优以及功能测试。 uverbs是RDMA(Remote Direct Memory Access)的一种编程接口,它提供了底层、高效的编程接口,可以控制RDMA网络适配器中的硬件资源、创建和管理RDMA操作队列等功能,同时verbs接口也提供了一些...
