Error at initialisation of petsc4py

Hello,

I am using petsc4py quite often on my workstation and it works great, thank you for this !

I am trying to install it on the supercomputer of my lab where PETSc is already install. The installation was performed by the IT department and seems to be unusal. Indeed there is no directory named $PETSC_ARCH in $PETSC_DIR:

 -bash-4.1$ ls $PETSC_DIR
 bin  conf  include  lib  share

But anyway, the installation seems to be ok. So I have a run a batch through lsf with the command :

python setup.py test

which returned

Traceback (most recent call last):

I would really appreciate to use petsc4py and this supercomputer. Have you any idea how to correct this ? I am not sure the title I have chosen it the best and I did not find anything better !

Best,

Lucas

PS : On the supercomputer, MPI-SGI is used. It is known (see http://dedalus-project.readthedocs.org/en/latest/machines/nasa_pleiades/pleiades_mpi_sgi_intel.html) that when we do a “from mpi4py import MPI”, we core dump. Therefore, I replaced in my code every MPI.COMM_WORLD by PETSc.COMM_WORLD. And, for instance MPI.COMM_WORLD.bcast is replaced by PETSc.COMM_WORD.tompi4py().bcast.
