Hi, My job is behaving differently on its two nodes, refusing to MPI_Comm_spawn() a process on one of them but succeeding on the other. Please help me interpret the output that MPI is producing - I am hoping it will yield clues as to what is different between the two nodes.
Here is one instance: ====================== ALLOCATED NODES ====================== n002: flags=0x11 slots=3 max_slots=0 slots_inuse=0 state=UP n001: flags=0x13 slots=3 max_slots=0 slots_inuse=0 state=UP What do the differing flags values mean? Here is another instance: ======================== JOB MAP ======================== Data for node: n002 Num slots: 3 Max slots: 0 Num procs: 1 Process OMPI jobid: [24604,1] App: 0 Process rank: 0 Bound: N/A Data for node: n001 Num slots: 3 Max slots: 0 Num procs: 1 Process OMPI jobid: [24604,1] App: 0 Process rank: 1 Bound: socket 0[core 0[hwt 0]]:[B/././././././././.][./././././././././.] Why is the Bound output different between n001 and n002? Thanks for your help. Kurt
