NAME
       HPL_sum - Combine (sum) two buffers.

SYNOPSIS
       #include "hpl.h"

       void HPL_sum( const int N, const void * IN, void * INOUT, const
       HPL_T_TYPE DTYPE );

DESCRIPTION
       HPL_sum combines (sum) two buffers.

ARGUMENTS
       N       (input)                 const int
               On entry, N  specifies  the  length  of  the  buffers  to  be
               combined. N must be at least zero.

       IN      (input)                 const void *
               On entry, IN points to the input-only buffer to be combined.

       INOUT   (input/output)          void *
               On entry, INOUT  points  to  the  input-output  buffer  to be
               combined.  On exit,  the  entries of this array contains  the
               combined results.

       DTYPE   (input)                 const HPL_T_TYPE
               On entry,  DTYPE  specifies the type of the buffers operands.
