Re: [OMPI users] Is it not possible to run a program with MPI code without mpirun/mpiexec?

I just found out that there were missing updates for Windows in 
singleton module (in trunk but not in 1.5 branch). I'll make a CMR for this.

I have open-mpi v1.5.4, installed from the binary installer for

  MPI_Comm_size(MPI_COMM_WORLD,);
  MPI_Comm_rank(MPI_COMM_WORLD,);
  printf("hellow world from rank %d of %d.\n",rank,size);
  MPI_Finalize();
  return 0;
}

is compiled and linked without issue with

c:\temp\mpicc test.c

It also runs without issue with

c:\temp\mpirun test.exe

and prints the expected output. However, running the executable directly, as in

c:\temp\test

prints the following and then hangs:

[COMPUTERNAME:03060] [[34061,0],0] ORTE_ERROR_LOG: Value out of
bounds in file ../../../openmpi-1.5.4\orte\mca\oob\tcp\oob_tcp.c at
line 1193

Is this a bug? I normally expect mpi programs to run without problem
as a standalone executable. I should add that the mpi installation
does not have any directories/files named in the error log, only
pre-built binaries.

Thanks muchly,
