Foil 23 Fortran example:Blocking Receive MPI_RECV

From Fox Presentation Fall 1995 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox

integer status(MPI_STATUS_SIZE) An array to store status

integer mpierr, count, datatype, source, tag, comm

integer recvbuf(100)

count=100

datatype=MPI_REAL

comm=MPI_COMM_WORLD

source=MPI_ANY_SOURCE accept any source processor

tag=MPI_ANY_TAG accept anmy message tag

call MPI_RECV (recvbuf,count,datatype,source,tag,comm,status,mpierr)

Note source and tag can be wild-carded
