C – Troubleshooting InfiniPath MPI Troubleshooting

Q

Examples are given below.

In the following command, the HP-MPI version of mpirun is invoked by the full pathname. However, the program mpi_nxnlatbw was compiled with the QLogic version of mpicc. The mismatch will produce errors similar this:

$ /opt/hpmpi/bin/mpirun -hostlist "bbb-01,bbb-02,bbb-03,bbb-04" -np 4 /usr/bin/mpi_nxnlatbw

bbb-02: Not running from mpirun?.

MPI Application rank 1 exited before MPI_Init() with status 1 bbb-03: Not running from mpirun?.

MPI Application rank 2 exited before MPI_Init() with status 1 bbb-01: Not running from mpirun?.

bbb-04: Not running from mpirun?.

MPI Application rank 3 exited before MPI_Init() with status 1 MPI Application rank 0 exited before MPI_Init() with status 1

In the case below, mpi_nxnlatbw.c is compiled with the HP-MPI version of mpicc, and given the name of hpmpi-mpi_nxnlatbw, so that it is easy to see which version was used. However, it is run with the QLogic mpirun, which will produce errors similar to this:

$ /opt/hpmpi/bin/mpicc \ /usr/share/mpich/examples/performance/mpi_nxnlatbw.c -o hpmpi-mpi_nxnlatbw

$ mpirun -m ~/host-bbb -np 4 ./hpmpi-mpi_nxnlatbw
