[hpct] HPM issues: works with GNU compiler set

[Vitali A. Morozov]

Dear All;

I am sorry it took me so long to verify this but, in short, HPCT hpm 
part works with GNU compiler set for both Fortran and C++.

Thank you very much everyone, and particularly Christoph Pospiech, for 
the full list of necessary commands and examples!

Here are technical details for those interested. I was testing a serial 
mode only.

1) Fortran

=============
      program Test_HPM
      implicit none

      include "mpif.h"
#include "f_hpm.h"

      integer ierr

      call MPI_Init( ierr )

      call f_hpminit( 0, "Test_HPM" )
      call f_hpmstart( 0, "MEASURE" )
       ..............
      call f_hpmstop( 0 )
      call f_hpmterminate( 0 )

      call MPI_Finalize( ierr )
      stop
      end
==============

Here both includes are important and exactly as written. The second with 
the # sign will be processed by pre-processor.

To compile:

mpif90 -g -x f77-cpp-input -std=gnu -Wp,-DHPM -I$(IHPCT_BASE)/include -c 
Test_HPM.f
mpif90 -g -dynamic -o Test_HPM Test_HPM.o -L$(IHPCT_BASE)/lib -lhpm 
-llicense

Here "-x f77-cpp-input -Wp,DHPM" is important.

To run:

TASK=Test_HPM
qsub -A Performance -q short -t 0:10:00 -n 1 --proccount 1 --mode smp -O 
$TASK \
--env IHPCT_BASE=$IHPCT_BASE:LD_LIBRARY_PATH=$IHPCT_BASE/lib $TASK

Here, LD_LIBRARY_PATH is important.

As promised, the result is two files, Test_HPM.viz and Test_HPM.hpm. The 
first can successfully be processed with peekperf, the second is a 
regular text file with counter information.

2) C++, simpler, and I give only the differences

===================
#include <mpi.h>
#include "libhpm.h"

int main(int argc, char **argv)
{
  MPI::Status stat;

  MPI::Init( argc, argv );
  int rank = MPI::COMM_WORLD.Get_rank();
 
  hpmInit( rank, "hpct-hcpm" );
  hpmStart( 1, "multiply-regular" );
  ........
  hpmStop( 1 );
  hpmTerminate( taskID );

  MPI::Finalize();
  return 0;
}
==================

mpicxx -g  -I$(IHPCT_BASE)/include -c Test_hpm.cxx
mpicxx -g -dynamic -o Test_hpm Test_hpm.o -L$(IHPCT_BASE)/lib -lhpm 
-llicense

TASK=Test_HPM
qsub -A Performance -q short -t 0:10:00 -n 1 --proccount 1 --mode smp -O 
$TASK \
--env IHPCT_BASE=$IHPCT_BASE:LD_LIBRARY_PATH=$IHPCT_BASE/lib $TASK

Once again, thank you very much, Christoph!

with best regards,

Vitali

p.s. An open issue is how to make the same with IBM XL compiler???
