When using mpirun, the process is not created normally and the size is always zero. However, mpi works normally when mpirun.mpich is used. mpirun enter image description here mpirun.mpich enter image description here
How can I work like the mpirun.mpich result when I use mpirun?
Executing the mpi4py.get_config() command resulted in the following results. {'mpicc': '/usr/bin/mpicc', 'mpicxx': '/usr/bin/mpicxx', 'mpifort': '/usr/bin/mpifort', 'mpif90': '/usr/bin/mpif90', 'mpif77': '/usr/bin/mpif77'}
I heard that both MPICH and OpenMPI versions are installed for MPI, but I'm not sure exactly what the problem is.
