ncclProxyProgress执行proxyProgress操作 ncclProxyProgress 通过在while循环中,progressOps函数执行添加的progress动作,而ncclProxyGetPostedOps是用来添加progress动作。(progress可理解为sendProxyProgress与recvProxyProgress的完整过程) 注意,为了不因为频繁的导致调用ncclProxyGetPostedOps而出现问题,设置了计数变量proxyOpAppendC...
netTransport:setup,connect,free,proxySharedInit,proxySetup,proxyConnect,proxyFree,proxyProgress collNetTransport:setup,connect,free,proxySetup,proxyConnect,proxyFree,proxyProgress,proxyRegister,proxyDeregister 4. 以netTransport为例,定义了下列函数实现,我们下面进行详述canConnect sendSetup/recvSetup sendConnect/re...
Hello! I used some tracing tools to trace all-reduce operation in NCCL and found that the execution of runRing in all_reduce.h in GPU are always related to sendProxyProgress() in net.cc which seems to be related to CPU. I wonder whether you could kindly provide me some hints about ...

It can be worked around by setting the following parameter: NCCL_MIN_NCHANNELS=4 Fixed Issues The following issues have been resolved in NCCL 2.16.5: ‣ Fix speed of IB NDR links ‣ Fix handling of EINTR in socket polling ‣ Improve proxy progress scheduling ‣ Fix resource cleanup ...

gpu0在kernel里write data,通知host proxy progress thread 0 in node 0 host proxy thread0 调用NET(一般是IB)去send data到host proxy progress thread1 in node1 host proxy progress thread1 recv data,gpu1在kernel里read data 两个GPU单机通信和多机通信的区别 ncclInfo转化为ncclQueueElem 的同时会转化为...
I try to debug ,found hung inp2pSendProxyProgress,and sub->transmitted=7, sub->done =0,I think this problem is cudaMemcpyAsync still not finish, why cudaMemcpyAsync not finish??? I try write demo but not face this problem,@sjeaugeycan give me some advice thanks?mainCIFAR10.txt...
