SYNOPSIS

9       #include "hpl.h"
10
11       int  HPL_send(  double * SBUF, int SCOUNT, int DEST, int STAG, MPI_Comm
12       COMM );

DESCRIPTION

15       HPL_send is a simple wrapper around  MPI_Send.  Its  main   purpose  is
16       to   allow  for some  experimentation / tuning  of this simple routine.
17       Successful  completion  is  indicated  by  the  returned   error   code
18       MPI_SUCCESS.   In  the case of messages of length less than or equal to
19       zero, this function returns immediately.

ARGUMENTS

22       SBUF    (local input)           double *
23               On entry, SBUF specifies the starting address of buffer  to  be
24               sent.
25
26       SCOUNT  (local input)           int
27               On  entry,   SCOUNT  specifies  the number of  double precision
28               entries in SBUF. SCOUNT must be at least zero.
29
30       DEST    (local input)           int
31               On entry, DEST specifies the rank of the receiving  process  in
32               the communication space defined by COMM.
33
34       STAG    (local input)           int
35               On  entry,   STAG specifies the message tag to be used for this
36               communication operation.
37
38       COMM    (local input)           MPI_Comm
39               The MPI communicator identifying the communication space.
