Ale:
   You should probably first check that your mpi is installed properly by 
running
some simple mpi programs. I then suggest you try the primer/pppWave.C program
that just uses P++ and no Overture, and then the primer/pWave.C which uses
Overture.

Hi Bill,

actually I used mpirun -np 2 ... and the


P++... Number_Of_Processors           = 1

is printed out 2 times, if i set -np 20 i see 20 times the same message.

I thought this was a problem, this means something is wrong with mpi?

It's the very first time for me I use mpi, that was installed by the
administrator...

Thanks again and sorry for bothering you

Cheers,

Ale

    Something is funny since P++ thinks there is only 1 processor.
Normally I would use mpirun -np 2 ...

Have you tried the parallel version ogen or of the pwave code in the
Overture/primer?


The parallel code can read grids generated from the serial ogen (and vice
versa).
