[OMPI users] Problem to Run Hello World on a desktop with Cygwin and OpenMPI 1.7.5

[Sergii Veremieiev]

Dear Sir/Madam,



I'm trying to compile and run a simple "Hello World" C++/MPI code on my
personal desktop machine (6-core Intel Core i7-3930K CPU with Windows 7 SP1
and Cygwin with the default built-in Open MPI 1.7.5 and GCC 4.8.2). I'm
beginner with this, never run parallel codes on desktops, only on a
cluster. Here is the code:



using namespace std;

#include "mpi.h"

int main(int argc, char *argv[])

{

   int noprocs, nid;

   MPI::Init(argc,argv);

   nid = MPI::COMM_WORLD.Get_rank();

   noprocs = MPI::COMM_WORLD.Get_size();

   if (nid==0) cout << "Hello from processor " << nid << " of " << noprocs
<< endl;

   MPI::Finalize();

}



Using “mpicxx -o Hello Hello.cpp” the code compiles without any problems
and generates an executable. However when I try to run the code using
“mpirun -np 1 Hello” or “mpiexec -n 1 Hello” the following error message is
returned:

It looks like orte_init failed for some reason; your parallel process is

likely to abort.  There are many reasons that a parallel process can

fail during orte_init; some of which are due to configuration or

environment problems.  This failure appears to be an internal failure;

here's some additional information (which may only be relevant to an

Open MPI developer):

  orte_session_dir failed

  --> Returned value Error (-1) instead of ORTE_SUCCESS

Please help me to understand what is the problem. For your information here
is the output of the following commands:



$ echo $PATH

$ echo $LD_LIBRARY_PATH



$ ompi_info -v ompi full --parsable

ompi_info: Error: unknown option "-v"

Type 'ompi_info --help' for usage.



I also attach a lengthy output of "ompi_info --all". Please do not hesitate
if you require any further information.



Best regards,
