Hi,

I've successfuly compiled OpenFOAM 1.6.x with Intel C++ compiler on a SGI Altix. I've used the SGI MPT implementation of MPI.

I've run a small sequential test simplefoam in pitzDaily dir.

Then I've decomposed the problem to run it with 2 processors but launching
mpirun -np 2 simpleFoam -parallel
give an error message:

MPI: calcul9sv4: 0x57f000004b093bc7:
MPI: calcul9sv4: 0x57f000004b093bc7: --> FOAM FATAL ERROR:
MPI: calcul9sv4: 0x57f000004b093bc7: Trying to use the dummy Pstream library.
MPI: calcul9sv4: 0x57f000004b093bc7: This dummy library cannot be used in parallel mode
MPI: calcul9sv4: 0x57f000004b093bc7:

MPI: calcul9sv4: 0x57f000004b093bc7:
MPI: calcul9sv4: 0x57f000004b093bc7: FOAM exiting

May be I've done something bad! At compile time loader was looking for
libPstream.so in ./lib/linuxIA64IccDPOpt/ but I found that this library was in ./lib/linuxIA64IccDPOpt/dummy/
and I added a link in ./lib/linuxIA64IccDPOpt/ to allow compilation

Thanks for your help

Problem solved.

Allwmake had not compiled the parallel part of Pstream. I had added a new MPI config for MPT wich is the MPI version provided by SGI on my Altix server. I've called this new config MPT, of course .
But the script used to build Pstream tests for the existence of the 3 letters "MPI" in the name of the MPI config ($WM_MPLIB variable)

the solution is
- call the new configs MPIsomething
or
- remove this test in src/Pstream/Allwmake

Hello Foamers. I am getting a similar error when I attempt to run OpenFOAM 1.6.x in parallel as well. I did check and Pstream/mpi was compiled. So can anyone give me any advise as to why I would be getting such an error from OpenFOAM. Please help.
