[mpich-discuss] Problem with MPE and MPICH2

[Manuel Holtgrewe]

Hi,

I have a problem using MPE with MPICH2. The following C++ program:

--8<--------
#include <cstdio>

#include <mpi.h>
#include <mpe.h>

int main(int argc, char **argv)
{
  MPI_Init(&argc, &argv);
  int rank;
  MPI_Comm_rank(MPI_COMM_WORLD, &rank);
  printf("Rank: %d\n", rank);

  int res = MPE_Init_log();
  printf("R%02d, MPE_Init_log() == %d\n", rank, res);

  res = MPE_Finish_log("foo");
  printf("R%02d, MPE_Finish_log(\"foo\") == %d\n", rank, res);
  MPI_Finalize();
  return 0;
}
--8<--------

Crashes as follows:

$ mpiexec -n 1 ./mpe
Rank: 0
R00, MPE_Init_log() == 0
Enabling the Default clock synchronization...
R00, MPE_Finish_log("foo") == 0
rank 0 in job 51  **HOST**_53437   caused collective abort of all ranks
  exit status of rank 0: killed by signal 10

$ mpiexec -n 2 ./mpe
Rank: 0
R00, MPE_Init_log() == 0
Rank: 1
R01, MPE_Init_log() == 0
Enabling the Default clock synchronization...
R00, MPE_Finish_log("foo") == 0
R01, MPE_Finish_log("foo") == 0
rank 0 in job 52  **HOST**_53437   caused collective abort of all ranks
  exit status of rank 0: killed by signal 10

If I remove the "MPE_Finish_log()" line, the program does not crash.

The problem occurs on Mac Os X and Linux using mpich2 1.0.8 with g++ 4.3.

Bests,
