FoSSI - Family of Simplified Solver Interfaces

The Family of Simplified Solver Interfaces is designed for an easy integration and selection of parallel solvers in Fortran codes which make use of compressed sparse row matrix format (CSR). FoSSI contains rather similar interfaces to the most popular and wide spread parallel solver libraries obtainable on the web: PETSC, HYPRE, AZTEC and MUMPS. Furthermore, an interface to the PILUT-library is included together with the PILUT-solver itself.

For details, please read a paper on FoSSI, published as technical report at BremHLR.

Remark:
You should compile Petsc with Hypre-support enabled.
