Bug#712526: freefem++: FreeFem++-mpi not working

Sun Jun 16 19:47:49 UTC 2013

Package: freefem++
Version: 3.19.1-1
Severity: normal

Dear Maintainer,
I installed freefem++ on the default Wheezy (7.1) with apt-get, I also
installed freefem++-dev. I experienced the same issue on Wheezy (7.0).
FreeFem++ is working properly, but the parallel version FreeFem++-mpi does not.
I tried running the built-in examples of the examples++-mpi folder and they are
not working. The mentioned example files can be found at the following URL:
http://www.freefem.org/ff%2B%2B/ff%2B%2B/examples%2B%2B-mpi/
In particular, I tried running some test cases with both the following
commands:
FreeFem++-mpi chaleur3D-hips.edp
ff-mpirun -np 2 chaleur3D-mumps.edp
I obtain two kind of errors: msh3 libraries are missing or parallel solver
libraries are missing, for instance:

$ FreeFem++-mpi chaleur3D-pastix.edp

    2 : load "msh3"

         fail :

'.so'

I partially solved these issues compiling from source FreeFem++ v.3.23 with the
configure command:
../configure '--enable-download'
then make and make install as usual.
This however does not solve completely the problem since the make check gives
80 out of 84 test passed.

I have gcc 4.7.2 and openmpi 1.4.5.
I made HIPS, MUMPS and Super LU parallel solvers work, while HYPRE, pARMS and
pastix still do not. Here is one example of a working parallel simulation with
HIPS:

$ ff-mpirun -np 2 chaleur3D-hips.edp
'/opt/openmpi/1.6.4/bin/mpirun' -np 2 /usr/local/bin/FreeFem++-mpi chaleur3D-
hips.edp

and an example of a failing simulation with HYPRE:

mpirun noticed that the job aborted, but has no info as to the process
that caused that situation.

The other non-working solvers give the same error.
