Hi Siegmar,
Could you please send the output of ompi_info command under you 64 bit
env? And could you please also check if you have CCP or HPC pack
installed? The incorrect configuration of that might cause Open MPI hanging.
Regards,
Shiqing

Hi Shiqing,
It seems that the runtime environment is messed up with the different
versions of Open MPI. I suggest you completely remove all the
installations and install 1.6.1 again (just build the installation
project again). It should work without any problem under Cygwin too.
I removed openmpi-1.6 und rebuilt openmpi-1.6.1. Now I can compile and
run a program in 32-bit mode but have still some problems.

Sorry! You were supposed to get help about:
invalid if_inexclude
But I couldn't open the help file:
D:\...\prog\mpi\small_prog\..\share\openmpi\help-mpi-btl-tcp.txt:
No such file or directory. Sorry!
---------------------------------------------------------------------
Hello!
Why does "mpiexec" look for the help file relativ to my current
program and not relative to itself? The file is part of the
package.
dir "c:\Program Files (x86)\openmpi-1.6.1\share\openmpi\help-mpi-btl-tcp.txt"
...
03.04.2012 16:30 631 help-mpi-btl-tcp.txt
Must I change something in the source code or can I set an environment
variable for help files? Why does "mpiexec" want to give some help at all?
I don't get this message for openmpi-1.5.1.

I can also compile in 64-bit mode but the program hangs.

It's the same if I compile a 64-bit program with openmpi-1.5.1. The program
itself is very small.
#include <stdio.h>
#include <stdlib.h>
#include "mpi.h"
int main (int argc, char *argv[])
{
MPI_Init (&argc, &argv);
printf ("Hello!\n");
MPI_Finalize ();
return EXIT_SUCCESS;
}
Any ideas why the 64-bit version hangs? Thank you very much for any help
in advance.
Kind regards
Siegmar
