Hi Nicolas,
Are you using ubuntu?
I have a machine with a similar architecture and I install ubuntu, but
most of the time, because ubuntu never put the library where you think
they are, it is much easier to install petsc with mpi etc..
I manage to get it to run with that with openmpi install in my local
directory.
so first make sure you added
export F90=gfortran
export F77=gfortran
export CC=gcc
export PETSC_DIR=/home/laetitia/Software/petsc-3.0.0-p12
export PETSC_ARCH=ompi_mumps_opt
export MPI_DIR=$PETSC_DIR/$PETSC_ARCH/bin
export PATH=$MPI_DIR:$PATH
export CXX=g++
to your bash file
and then try these options: (I took then from my config log) this are
for optimised version, I am not sure you need one with debug... most of
the problems you may encounter are more likely to come from Gale than
from Petsc and it is better for you to optimise your solving time.
Anyway you can build both.. so that if you have a problem you can
recompile gale with debug version of petsc.
./config/configure.py --download-mumps --download-scalapack
--download-blacs --download-parmetis --download-openmpi --download-ml
--download-hypre --download-f-blas-lapack ifneeded
-PETSC_ARCH=ompi_mumps_opt --with-64-bit-pointers --with-shared=0
--with-debugging=0
then you should not forget to use the mpi which is located in petsc when
you run Gale
it should work directly but to check whch mpi you are using you can type
which mpiexec in your command line
good luck
