Hello,

ff-mpirun is aborted whenever I try to run a script with “ff-mpirun -np 4 script.edp” and I get the below message.

freefem++ and mpicc work without a problem in my machine.

The same ff-mpirun scripts are working when using another machines.

Does anyone have any idea about the problem?

Thank you for the help,

Abdelhak.

It looks like MPI\_INIT failed for some reason; your parallel process is  
likely to abort. There are many reasons that a parallel process can  
fail during MPI\_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):

## ompi\_mpi\_init: ompi\_rte\_init failed → Returned “(null)” (-43) instead of “Success” (0)

## Primary job terminated normally, but 1 process returned a non-zero exit code. Per user-direction, the job has been aborted.

mpiexec detected that one or more processes exited with non-zero status, thus causing  
the job to be terminated. The first process to do so was:

Process name: [[54695,1],0]  
Exit code: 1
