After I updated my home computer from Fedora 17 to 18 MPI programs
stopped working.
I have a very simple program :
#include <stdlib.h>
#include <stdio.h>
#include <mpi.h>
int main( int argc, char * argv[] )
{
int rank, size;
MPI_Init(&argc, &argv);
MPI_Comm_rank(MPI_COMM_WORLD, &rank);
MPI_Comm_size(MPI_COMM_WORLD, &size);
printf("my rank is %i of %i\n", rank, size );
MPI_Finalize();
return EXIT_SUCCESS;
}
I can compile it with :
mpicc -g -o mpi_simple mpi_simple.c
but when I run it with :
mpirun -n 1 ./mpi_simple
I get :
[murron.hobbs-hancock:05668] [[55801,1],0] ORTE_ERROR_LOG: Error in file

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

[murron.hobbs-hancock:5668] *** An error occurred in MPI_Init

--------------------------------------------------------------------------
An MPI process is aborting at a time when it cannot guarantee that all
of its peer processes in the job will be killed properly. You should
double check that everything has shut down cleanly.
Reason: Before MPI_INIT completed
Local host: murron.hobbs-hancock
PID: 5668
--------------------------------------------------------------------------
--------------------------------------------------------------------------
mpirun has exited due to process rank 0 with PID 5668 on
node murron.hobbs-hancock exiting improperly. There are two reasons this
could occur:
1. this process did not call "init" before exiting, but others in
the job did. This can cause a job to hang indefinitely while it waits
for all processes to call "init". By rule, if one process calls "init",
then ALL processes must call "init" prior to termination.
2. this process called "init", but exited without calling "finalize".
By rule, all processes that call "init" MUST call "finalize" prior to
exiting or it will be considered an "abnormal termination"
This may have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
--------------------------------------------------------------------------
I'm actually able to run the generated executable on another computer
just fine.
I tried using gdb to step through util/nidmap.c from 148 but whatever
goes wrong is too far away for me to find it.
Does anybody have any clue where I should look?
