Abstract. In this paper, the methodsand implementation techniques used for the nonsymmetric sparse linear system solver, MCSPARSE, on the Cedar system are described. A novel reordering scheme (H*) upon which the solver is based is presented. The tradeoffs discussed include stability and fill-in control, hierarchical parallelism, and load balancing. Experimental results demonstrating the effectiveness of the solver with respect to each of these issues are presented. We also address the implications of this work for other parallel processing systems. 1. Introduction. Several, |
