Dear Getfem users,
I'm struggling with a problem of running Getfem in parallel (serial runs
well).
My system is Ubuntu 11.10, 64 - bit.
Getfem release version 4.1.1
Installed MPICH2 (including development files), MUMPS 4.9.2 (with dev
files) and ATLAS 3.8.4 (with dev).
Compiling with gcc 4.6.1
configured getfem as: ./configure --with-pic --enable-paralevel=2
(configure recognized MPICH2, MUPS and ATLAS and said that Getfem will be
built in parallel)
Building getfem succeeds, but "make check" was running with some linking
problems for the very first test.
Searching the web I discovered some problem with MPICH2 where people say
that I should also link libmpl after mpich2 which I did
by editing Makefile LIBS in the main and tests directories (not neat, but I
don't know how I can force this linkage with configure)
This resolved the linking problems and most of the tests where built,
however I got stuck with building schwarz_additive.cc.
This tests does #include <mpi++.h> which I don't have. Somewhere I've read
that I can use mpi.h instead (or mpicxx.h) which I did
(by replacing #include <mpi++.h> to #include <mpich2/mpi.h> and
then #include <mpich2/mpicxx.h>). This produces many template and other
errors.
So, do I have to install some separate mpi c++ bindings? It is a bit
strange, as I thought MPICH2 provides it.
But OK, even though I still cannot build schwarz_additive.cc I thought I
can run the tests that were built.
So I tried to run
./laplacian laplacian.param
and
./nonlinear_elastostatic nonlinear_elastostatic.param
Both tests did some initiation but both ended with MPI error. For instance
nonlinear_elastostatic produced:
MESH_TYPE=GT_PK(3,1)
FEM_TYPE=FEM_PK(3,2)
INTEGRATION=IM_TETRAHEDRON(6)
Selecting Neumann and Dirichlet boundaries
Attempting to use an MPI routine before initializing MPICH
running ./elastostatic elastostatic.param gave:
Trace 1 in elastostatic.cc, line 497: Running parallelized Getfem level 2

I would really appreciate your advice,
regards,
Andriy
