SYNOPSIS

#include "hpl.h"

int HPL_send( double * SBUF, int SCOUNT, int DEST, int STAG, MPI_Comm COMM );

Successful completion is indicated by the returned error code MPI_SUCCESS. In the case of messages of length less than or equal to zero, this function returns immediately.

ARGUMENTS

SBUF (local input) double *: On entry, SBUF specifies the starting address of buffer to be sent.
SCOUNT (local input) int: On entry, SCOUNT specifies the number of double precision entries in SBUF. SCOUNT must be at least zero.
DEST (local input) int: On entry, DEST specifies the rank of the receiving process in the communication space defined by COMM.
