We still use this option in OpenMPI (1.6.x, 1.7.x) with OpenFOAM and other
applications to attach each process on its core because sometimes linux move
processes and 2 process can run on the same core, slowing the application. Even
if we do not use full nodes.
'--bind-to-core' is only not applicable if you mix OpenMP and MPI as all your
threads will be binded to the same core but I do not remember that OpenFOAM does
