Connecting MUMPS (Parallel) to Code_Aster

Hello,

I'm able to compile Code_Aster 14.6, and all of its included sub-packages, on Ubuntu 20.04, but MUMPS compiles/installs a sequential (non-parallel) version by default.

From reading, it appears that I need to compile the parallel version of MUMPS first, then modify setup.cfg before compiling the full package. I'm able to compile MUMPS parallel version without issue (tested with the included MUMPS samples under ./examples/), and I copied the entire ./mumps-5.1.2/ folder to /opt/aster/public/ (to keep my entire Code_Aster installation in one location). Next, I modified the bottom of setup.cfg:

_install_mumps = False
HOME_MUMPS='/opt/aster/public/mumps-5.1.2'

However, when I load up astk with a project (one that previously ran sequentially without issue), I now receive an error message that MUMPS isn't installed.

Re: Connecting MUMPS (Parallel) to Code_Aster

Hello,

I was able to build CA 14.6 MPI (also with PETSc) by following this great description:

h_ttps://hitoricae.com/2020/10/31/code_aster-14-6-parallel-version-with-petsc/

There is a slight error in the end though. If I remember correctly, a '/' is missing in the line before '$ASTER_ROOT' (without the ' of course..):

$ ./waf configure --use-config-dir=$ASTER_ROOT/14.6/share/aster --use-config=Ubuntu_gnu_mpi --prefix=$ASTER_ROOT/PAR14.6MUPT

I followed the description EXACTLY (versions and order have to be exact...etc.), I also tried 20.04LTS, but couldn't install superlu correctly from the Ubuntu repos. Maybe this is possible with the now updated U20.04.

Hope it helps,

Mario.
