geneo4PETSc - implementation of the GenEO preconditioner with PETSc and SLEPc.

Prerequisites:

1. geneo4PETSc
   • CMake
   • dlopen utilities
   • Metis
   • MPI
   • Boost: Boost.MPI, Boost.Serialization
   • PETSc: configure --with-mpi=1 --download-mumps --download-scalapack ...
   • SLEPc: configure --download-arpack ...
2. test suite
   • python: argparse, numpy, matplotlib (for test suite)
   • diff (for test suite)

Note: if not done by "module load", you need to export PKG_CONFIG_PATH/CMAKE_PREFIX_PATH (check the doc/wiki).

Note: prq.sh can help to build prerequisites (caution: export variables when script ends).
~/geneo4PETSc> ./prq.sh petsc slepc

Build and test:

~/geneo4PETSc> pip install argparse numpy matplotlib
~/geneo4PETSc> module load cmake metis mpi boost petsc slepc
~/geneo4PETSc> mkdir BUILD; cd BUILD
~/geneo4PETSc/BUILD> cmake ..; make all checkv

Note: you need to check that all prerequisites are consistent unless link may break (check the doc/wiki).

Usage:

~/geneo4PETSc/BUILD> ./src/geneo4PETSc --help

Note: in case the solver diverges, check the doc/wiki.

Examples:

Look at examples provided by the test suite.
