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
