DESCRIPTION

Stub for MPI_sendrecv routine using the same calling sequence, except for datatypes, operators and communicators. Those are replaced by an equivalent string, described in the table below:
 
Types supported Operators supported Communicators recognized
"MPI_CHARACTER"* "MPI_OP_NULL" "EW"  (east-west)
"MPI_INTEGER" "MPI_MAX" "NS"  (north-south)
"MPI_INTEGER2" "MPI_MIN" "GRID" (full domain grid)
"MPI_REAL" "MPI_SUM" "BLOC" (inside local block)
"MPI_REAL8" "MPI_PROD" "BLOCMASTER" (between blocks master PEs)
"MPI_REAL4" "MPI_LAND" "ALL" (every PE)
"MPI_DOUBLE_PRECISION" "MPI_BAND" "DOMM", equivalent to "GRID"
"MPI_COMPLEX" "MPI_LOR" "DEFO" default communicator
"MPI_DOUBLE_COMPLEX" "MPI_BOR"
"MPI_LOGICAL" "MPI_LXOR"
"MPI_BXOR"
"MPI_MAXLOC"
"MPI_MINLOC"
* Note: MPI_CHARACTER for/pour RPN_COMM_bcastc only/seulement

This RPN_COMM routine send the message tagged with "sendtag" to the "dest" PE and receive a message form "source" PE tagged with "recvtag".
