Hi folks,
openMPI 1.4.1 seems to have another problem with my machine, or something on
it.
This little program here (compiled with mpif90) startet with mpiexec -np 4
a.out produces the following output:
Suriprisingly the same thing written in C-Code (compiled with mpiCC) works
without a probl
printf("not using Open MPI\n");
#endif
into your source code.

n you reconfigure it?
If you can, you could run it with -mca ess_base_verbose 5 to see if it is
picking up the correct modules.
It really looks like your application was built with an older version, or
compiled against something like mpich.

ou do an "mpirun -np 4 env" you should seeOMPI_COMM_WORLD_RANK range 0
thru 3. I am curious if you even see OMPI_* env-vars and if you do is this one
0 for all procs?

Yeah, I sure that I use the right mpirun.
which mpirun leads to /usr/users/pankatz/OPE
are using the right
mpirun?

Yes, I did that.
It ist basically the same problem with a Fortran version of this little
program. With that I used the mpif90 command of openMPI.

Hi all,
there's a problem with openMPI on my machine. When I simply try to run this
little hello_world-program on multiple processors, the output isn't as
expected:
*
C code:
#include
#include
#include
int main(int argc, char **argv)
{
int size,rank;
char hostname[50];
MPI_Init(&a
