Parallel Sparse Basic Linear Algebra Subroutines (PSBLAS)
Provides a framework to enable easy, efficient and portable implementations of iterative solvers
for linear systems, while shielding the user from most details of their parallelization. The
interface is designed keeping in view a Single Program Multiple Data programming model on
distributed memory machines.
