HIPS (Hierarchical Iterative Parallel Solver) is a C-library
for solving large sparse linear systems on parallel platforms. The code provides a hybrid method which blends
direct and iterative solvers.
HIPS exploits the partitioning and multistage ILU techniques developed in
the PHIDAL algorithm [see,
Tech. reports]
to enable a highly parallel scheme whereby several subdomains can be
assigned a process.
PaStiX
is a Parallel Direct Solver for Sparse linear system. PaStiX can
also be
used as an iterative solver with a preconditioner based on block ILU(k)
factorizations. PaStiX use a MPI/thread implementation that is
usefull on multicore and SMP architectures (reduce the great overhead
of communication in direct solver).
