Proto: Simple、LL、LL128;不同的proto能提供不同的通信带宽,其中Simple能提供100%的理论带宽,LL能提供50%的通信带宽,LL128能提供93.75%的通信带宽。一般来说更在乎latency的会选择LL,更在乎带宽的会选择Simple,至于LL128,可能只在特定的硬件架构上能支持,用到的情况可能不是很多。关于proto的解释可见What is LL1...
算法带宽的计算过程:取算法基数值 busBw= ncclTopoGraph->bwIntra ,经过NCCL_ALGO/NCCL_PROTO/NCCL_TOPO等场景修正(即乘以一定的比例系数)后,把结果存储在comm中: 参数含义:coll: 集群通信操作;a: 通信算法;p: 协议 时延计算:首先考虑基础时延:comm->latencies[coll][a][p] = baseLat[a][p]; 带宽与时延...

Context I tried multi-node training with model A, it works fine. Then I tried the same setting with model B (same repo, different config) and faced this error. It looks likeopCount cstarts to produce this error. Also, I triedNCCL_PROTO=SIMPLEand then the program raisestorch.cuda.OutOf...
