Hello Johannes,
Thank you for your message. It greatly helps me to go further. Now I
encounter a problem inside the installation of PETSc.
At configure step, it can't download ML, ie. ml-6.2-p2.tar.gz and
propose to download it manually in order to use the configure option :
--download-ml=/yourselectedlocation/ml-6.2-p2.tar.gz
as a workaround.
I try this and it works. I have compiled PETSc.
Now, if I come back to fenics, how can I tell it that there is a
compiled PETSc next to it and to use it ?
If I relaunch the installation script of fenics, that is,
./install/fenics-install.sh , it begins a new installation of PETSc,
just next to the right one with the same error about downloading ML.
Regards,
Guy.

Hi Johannes,
I'd like our users to be able to run fenics on our cluster. So a
runable version first, and next a maybe more optimized one.
"gcc", /usr/bin/gcc, is version 4.3 of the GNU compiler.
We have version 4.7 as /usr/bin/gcc-4.7
Where is the hashdist profile file in order to modify the gcc
default name ?
You will have to create the hashdist profile, either from scratch or
by modifying an existing profile. There are profiles that you can use
in hashstack and in fenics-developer-tools. You can for example do the
following:
git clone
https://bitbucket.org/fenics-project/fenics-developer-tools.git
cd fenics-developer-tools
cp install/profiles/fenics.Linux.yaml local.yaml
Now, open local.yaml and add something like the following:
parameters:
PROLOGUE: |
export CC=/usr/bin/gcc-4.7; export CXX=/usr/bin/g++-4.7; export
FC=/usr/bin/gfortran-4.7
To use OpenMPI instead of MPICH, replace
mpi:
use: mpich
with this:
mpi:
use: openmpi
When you are satisfied with your profile, run
./install/fenics-install.sh
The fenics-install.sh script will detect and use your local.yaml profile.
Note that you should set the same variables when compiling/running
FEniCS programs as you do in the PROLOGUE. In the case above, this will be
source fenics.custom
export CC=/usr/bin/gcc-4.7
export CXX=/usr/bin/g++-4.7
export FC=/usr/bin/gfortran-4.7
Johannes
