Subject: [OMPI users] execution problem on remote nodes with MPI 1.3

Hello

I've a problem with a parallel execution of my personal mpi program.

When I execute it on localhost it works fine, but when I try to run it with two
machines I receive this error:

pietro_at_pietro-laptop:~/Scrivania$ mpirun --
prefix /home/user/MPI/ -np 4 --host user_at_xxx.yyy.zzz.kkk algo1.exe a2.txt b2.
txt
user_at_xxx.yyy.zzz.kkk's password:
[user:04778] *** Process received signal
***
[user:04778] Signal: Segmentation fault (11)
[user:04778] Signal code:

3] algo1.exe [0x8048b41]
[user:04778] *** End of error message ***

--------------------------------------------------------------------------

mpirun noticed that process rank 0 with PID 4778 on node user_at_xxx.yyy.zzz.kkk
exited on signal 11 (Segmentation fault).

--------------------------------------------------------------------------

where:
-> xxx.yyy.zzz.kkk is the IP of the other machine.
-> /home/user/MPI/
is the installation path of MPI 1.3 of the other machine

I hope that someone
can give me a some advices to solve this problem.
Thanks for your time
