HPL_send - Man Page

Send a message.


#include "hpl.h"
 int HPL_send( double * SBUF, int SCOUNT, int DEST, int STAG, MPI_Comm COMM );


HPL_send is a simple wrapper around  MPI_Send.  Its  main  purpose is to  allow for some  experimentation / tuning  of this simple routine. 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.


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.

STAG    (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.
