Abstract:

This grant concerned the case of vector processors such as the CRAY-1 in the solution of sparse systems of equations. The study produced three major classifications of results 1 Algorithms and related mathematical software for sparse solution on single processors uniprocessors 2 Preliminary projection of vector multiprocessor performance on linear algebra codes and 3 Cooperative work on vector sparse matrix algorithms with AFFDL for CFD and structures codes, and with UCBerkeley on for circuit simulation.
