CarpetLib: Make many MPI experiments configurable
Add new parameters:
BOOLEAN interleave_communications:
Try to interleave communications with each other; each processor
begins to communicate with its 'right neighbour' in rank, instead of
with the root processor
BOOLEAN vary_tags:
Use different tags for each communication
BOOLEAN barrier_between_stages:
Add a barrier between the communication stages (slows down, but may
make timing numbers easier to interpret)
BOOLEAN combine_sends:
Send data together and in order of processor ranks
BOOLEAN reduce_mpi_waitall:
Call MPI_Waitall only for requests that are not null
BOOLEAN use_mpi_send:
Use MPI_Send instead of MPI_Isend
BOOLEAN use_mpi_ssend:
Use MPI_Ssend instead of MPI_Isend
