Abstract
PARASOL is an ESPRIT IV Long Term Research Project whose main goal is to build and test and portable library for solving large sparse systems of equations on distributed memory systems. There are twelve partners in five countries, five of whom are code developers and five end users. The software is written in Fortran 90 and uses MPI for message passing. There are routines for both direct and iterative solution of symmetric and unsymmetric systems. The final library will be in the public domain. We discuss the PARASOL Project with particular emphasis on the algorithms and software for direct solution that are being developed by RAL and CERFACS. The underlying algorithm is a multifrontal one with a switch to ScaLAPACK processing later in the factorization (and solution).
