I am running the v-1.10.7 OMPI package that is available via the Cygwin package manager. I have a requirement to run my OMPI application standalone on a Windows/Cygwin system without any network connectivity. If my OMPI system is not connected to the network, I get the following errors when I try to run my OMPI application: [SAXM4WIN:02124] [[20996,1],0] tcp_peer_send_blocking: send() to socket 12 failed: Transport endpoint is not connected (128) [SAXM4WIN:02124] [[20996,1],0] tcp_peer_send_blocking: send() to socket 12 failed: Transport endpoint is not connected (128)
I have tried the following qualifiers in my OMPI command to no avail: --mca btl ^tcp,self,sm So the question is, am I able to disable TCP networking, either via command line or code, if I only plan to use cores on a single machine for OMPI execution?
