Dear OpenMPI users,

is it possible to define some set of parameters for a range number of
processors and message size in openmpi-mca-params.conf ? For example:

if nprocs<256

some mca parameters...

if nprocs > 256

other mca parameters..

and the same related to message size?

Thanks in advance.
