Dear all,
I use the following code:
#include "stdlib.h"
#include "stdio.h"
#include "mpi.h"
#include "math.h"
#include "unistd.h" /* sleep */
int my_num, mpi_size ;
int
main(int argc, char *argv[])
{
MPI_Init(&argc, &argv) ;
MPI_Comm_rank(MPI_COMM_WORLD, &my_num);
MPI_Comm_size(MPI_COMM_WORLD, &mpi_size);
printf("%d calls MPI_Finalize()\n\n\n", my_num) ;
MPI_Finalize() ;
}
I compile and run the code on two different architectures with their own
version/installation of open-mpi, with the command lines:
$>mpicc -lm --std=c99 basis.c
$>mpiexec -n 1 a.out
On numerous runs of the executable, even with a nbproc equal to 1:
- Using a debian open-mpi v 1.2.7rc2 installation, my code always returns to
shell after the call to MPI_Finalize()
Kernel is 2.6.34 SMP, Intel P9600 2 cores
- Using a homemade open-mpi v 1.4.2 installation, my code runs as expected,
but instead of returning to the shell after the MPI_Finalize(), it can just
hangs in Sl+ state.
Kernel is 2.6.18-53.1.19.el5 SMP (RedHat), Quad-Core AMD Opteron 8356
I join the ompi_info of the 2 archs. I surely miss something... but what?
.Yves.
