Allow ports to be reused in gloo #353

Open H-Huang opened 1 year ago

H-Huang commented 1 year ago

Summary: ProcessGroupGloo and gloo seem to be opening and closing sockets without allowing the port to be reused. We see this issue pop up in larger training jobs "Address already in use" and we assume it to be because all the ephemeral ports are exhausted.

This diff allows ports to be reused, we see a reduced number of ports being in TIME_WAIT state.
