chamois-singularity

A recipe file for a singularity containerized version of Moose and Chamois. Chamois requires the constitutive model library Marmot. The container environment is based either on Centos 8, GCC-9, CMake 3.18, and OpenMPI 4.0.2 or alternatively Debian 11, gcc-10, CMake 3.18, and OpenMPI 4.0.2. Note that libMesh is built only in opt mode.

Instructions:

• Ensure that moose, chamois and Marmot repositories are available
• Build: MOOSE_DIR=/moose/repo/dir MARMOT_DIR=/marmot/repo/dir CHAMOIS_DIR=/chamois/repo/dir sudo singularity build chamois-singularity.simg chamois-singularity-XXX.def
• Optional: Pass SINGULARITYENV_MAKE_JOBS=XX to set the number XX of make jobs during building
• Optional: Pass SINGULARITYENV_DELETE_GIT=TRUE to delete all Moose, PETSc and libMesh (and submodule) .git repositories in order to reduce container size
• Execute: singularity exec chamois-singularity.simg /projects/chamois/chamois-opt -i inputfile.i
• Execute with MPI: mpiexec -np XX singularity exec chamois-singularity.simg /projects/chamois/chamois-opt -i inputfile.i
