I suggest to also use your mpirun command's pinning options if
available. This can be an issue since MPI will allocate memory before
thorns hwloc and SystemTopology have a change of pinning the process so
that you may end up with cores having to use memory that is physically
attached to the "other" sockets in multi-socket systems.

There is unfortunately nothing any thorn can do about this since MPI may
allocate memory as soon as MPI_Init is called by the flesh.
