[Trilinos-Users] Exodus and MPI

[Andrea Penza]

Hi all,

I have problems executing Sundance with ExodusII mesh. I'm trying to run
it with MPI on the two processors of my DualCore. I've tested MPI and
Exodus separately and everything was working. 
Now the problem is that my system look for two splitted files for the
mesh, particularly it search *.pxo file format.
The system reports this message at runtime:

andrea at andrea-MacBookPro:~/Projects/trilinos-10.8.3-Source/MyApps/LaplaceScalar$ time mpirun -np 2 ./LaplaceScalarExo.exe 
Teuchos::GlobalMPISession::GlobalMPISession(): started processor with
name andrea-MacBookPro and rank 0!

As you can see, my system look for a
file ../Mesh/exodusii/square-2-0.pxo for the process with rank 0, and
the file ../Mesh/exodusii/square-2-1.pxo for the rank 1.
The source mesh file name is square.exo in the dir Mesh/exodusii. 
Thanks a lot to everyone could help me!
Kind regards,

Andrea
