The patch works great, i can now see the precondition environment variable if i do mpirun -n 2 -host node1 <prog> and my <prog> runs just fine, However if i do srun --resv-ports -n 2 -w node1 <prog> I get [node1:16780] PSM EP connect error (unknown connect error): [node1:16780] node1 [node1:16780] PSM EP connect error (Endpoint could not be reached): [node1:16780] node1 PML add procs failed --> Returned "Error" (-1) instead of "Success" (0) I did notice a difference in the precondition env variable between the two runs mpirun -n 2 -host node1 <prog> sets precondition_transports=fbc383997ee1b668-00d40f1401d2e827 (which changes with each run (aka random)) srun --resv-ports -n 2 -w node1 <prog> sets precondition_transports=0000184500000000-0000000100000000 (which doesn't seem to change run to run)
