In this case, a value of SOCKET_ERROR is returned with the error code set to WSAEWOULDBLOCK. The select or WSAEventSelect functions can be used to determine when more data arrives.If the socket is connection-oriented, the remote side has shut down the connection gracefully, and all data ...

It's pretty much the same for me. I do not getSocketRecvErrorwhen I run commands on one host, but I get it when I run it on multiple hosts. It's weird because the command is the same. The exception occurs when I print STDOUT of the second host. ...
What messages were in the log prior toTENCENT64:16736:16986 [1] include/socket.h:194 WARN Call to recv failed : Connection reset by peer? Can you checkifconfig, and if you see interfaces likedocker0, add-x NCCL_SOCKET_IFNAME=^docker0?
These calls return the number of bytes received, or -1 if an error occurred. In the event of an error,errnois set to indicate the error. When a stream socket peer has performed an orderly shutdown, the return value will be 0 (the traditional "end-of-file" return). Datagram sockets ...
如果套接字上沒有可用的傳入數據,recv呼叫會封鎖並等候數據根據WSARecv所定義的封鎖規則來抵達,除非套接字未封鎖,否則不會設定 MSG_PARTIAL 旗標。 在此情況下,會傳回 SOCKET_ERROR的值,並將錯誤碼設定為WSAEWOULDBLOCK。select、WSAAsyncSelect或WSAEventSelect函式可用來判斷何時有更多數據送達。

Otherwise, a value of SOCKET_ERROR is returned, and a specific error code can be retrieved by callingWSAGetLastError.

这里只描述同步Socket的send函数的执行流程。当调用该函数时,send先比较待发送数据的长度len和套接字s的发送缓冲的 长度, 如果len大于s的发送缓冲区的长度,该函数返回SOCKET_ERROR;如果len小于或者等于s的发送缓冲区的长度,那么send先检查协议 是否正在发送s的发送缓冲中的数据,如果是就等待协议把数据发送完,如果协议...
