mpich-shmem with Ubuntu 9.10

Asked by Anton Gladky

Hi, all!

Is anybody using ESyS+mpich-shmem on Ubuntu 9.10. It seems, that after New Year started, some packages where updated and they broke normal ESyS work with mpich. After I start the simulation, I get:

[IAM004:11828] *** Process received signal ***

OpenMPI is working normally, but https://answers.launchpad.net/esys-particle/+question/90446 still happens with more than 2 processes.

Hi Anton,

Did you manage to resolve this problem on Ubuntu-9.10? As yet I haven't bothered to upgrade to that OS as I'm pretty happy with 9.04. Perhaps if package upgrades were responsible, a reinstall of ESyS-Particle might fix the problem.

Cheers,

Dion.

Hi, Dion!

I have just fixed the problem. The problem is that it is not a good idea to have mpich and opempi -dev packages in one time. You can compile both of them, but mpich is not working after that.

For compilation I used next "configure" parameters:

#OPENMPI
./configure CC=mpicc.openmpi CXX=mpicxx.openmpi
To start the simulation "mpirun.openmpi..." command

#MPICH-SHMEM
./configure CC=mpicc.mpich-shmem CXX=mpicxx.mpich-shmem
To start the simulation "mpirun.mpich-shmem..." command

Hope, it will be useful for somebody.

OpenMPI is still have a problem with hanging with more than 2 working threads https://answers.launchpad.net/esys-particle/+question/90446

Thanks.
