HPL_recv(3)		     HPL Library Functions		   HPL_recv(3)

NAME
       HPL_recv - Receive a message.

SYNOPSIS
       #include "hpl.h"

       int  HPL_recv(  double  * RBUF, int RCOUNT, int SRC, int RTAG, MPI_Comm
       COMM );

DESCRIPTION
       HPL_recv is a simple wrapper around  MPI_Recv.  Its  main   purpose  is
       to   allow  for some  experimentation / tuning  of this simple routine.
       Successful  completion  is  indicated  by  the  returned	  error	  code
       HPL_SUCCESS.   In  the case of messages of length less than or equal to
       zero, this function returns immediately.

ARGUMENTS
       RBUF    (local output)	       double *
	       On entry, RBUF specifies the starting address of buffer	to  be
	       received.

       RCOUNT  (local input)	       int
	       On  entry,   RCOUNT  specifies  the number  of double precision
	       entries in RBUF. RCOUNT must be at least zero.

       SRC     (local input)	       int
	       On entry, SRC  specifies the rank of the	 sending   process  in
	       the communication space defined by COMM.

       RTAG    (local input)	       int
	       On  entry,   STAG specifies the message tag to be used for this
	       communication operation.

       COMM    (local input)	       MPI_Comm
	       The MPI communicator identifying the communication space.
