BEmap_MPIcomm_Version
MPI communication version of BE_MAP (CV)
EXPERIMENTAL OPTION:
Switch between different implementations of the MPI-communication within the
BE_MAP computation. This switch is intended to be used while developing this feature and optimizing its performance. It should currently NOT be used in production systems!
BEmap_MPIcomm_Version = 1 (
no longer available): Original version of the mapping which broadcasts every value from the parent process of the boundary element to all processes
BEmap_MPIcomm_Version = 2 :
Stable version of the mapping which uses a collective MPI communication across all processes
BEmap_MPIcomm_Version = 3 (default) : Version which uses a collective MPI communication only between the rank zero process of each shared memory group
The versions 2 and 3 only differ if more than a single shared memory group of processes exits, i.e. the simulation is running on more than a single node.
