Hi, I have two ipv6 only machines, I configured/built OMPI version 3.0 with - -enable-ipv6
I want to verify a simple MPI communication call through tcp ip between these two machines. I am using ring_c and connectivity_c examples. Issuing from one of the host machine… [mselvam@ipv-rhel73 examples]$ mpirun -hostfile host --mca btl tcp,self --mca oob_base_verbose 100 ring_c . . [ipv-rhel71a.locallab.local:10822] [[5331,0],1] tcp_peer_send_blocking: send() to socket 20 failed: Broken pipe (32) where “host” contains the ipv6 address of the remote machine (namely – ‘ipv-rhel71a’). Also I have passwordless ssh setup to the remote machine. I will attach a verbose output in the follow-up post. Thanks.
