We have shown that JTPACK90, in conjunction with PGSLIB, achieves encouraging parallel efficiencies for both simple and realistic problems within TELLURIDE. Nevertheless, much work remains. Preconditioning is one area on which we have only just begun to focus attention. For example, while we have had success using a loosely-converged CG solution of a low-order approximation to the full operator to precondition the CG solutions in our projection flow algorithm, we also want to examine other strategies, especially multilevel approaches.
