Internode runs hang over ch3:sock and fail or hang over nemesis, depending on OS version. Standard ping works fine internode on both sides, and so do my own socket-based programs. Any idea what this might be? Nemesis diagnostics under Ubuntu 16.04 LTS: c -f mpi.hosts -n 2 $PWD/pingpong Assertion failed in file src/mpid/ch3/channels/nemesis/netmod/tcp/socksm.c at line 597: hdr.datalen != 0 internal ABORT - process 1 Host list: 192.168.178.31 192.168.178.32 Platform: Intel, Ubuntu 16.04 LTS on one side, Ubuntu 14.04 LTS on the other, MPICH-3.2 on both, 100-Mbit Ethernet in between.
