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".
