I've installed intel mpi, use mpi-selector to choose intel mpi (installed in impi folder in /opt/intel/), but when I launch a job with
mpirun -n 8 ./HEART_MR
where HEART_MR is the executable, I obtain 8 processes running each one on a core, when I want a single process running on 8 cores. If I use openmpi, things happen how I expect to be.
Can you help me?
My machine has an eight core intel Xeon processor.
