Two new coarse-grain scheduling schemes, the levelwise and factorization path scheduling schemes, are examined. These schemes differ significantly from fine-grain scheduling schemes which have been proposed in the past. If a fine-grain scheduling scheme at the floating-point-operation level is an appropriate scheduling method for the iPSC hypercube parallel processing computer, then the levelwise scheduling scheme presented should have gain comparable to that obtained using the factorization path scheduling scheme. Since this is not the case, it may be concluded that a fine-grain scheduling scheme is not appropriate for parallel LU factorization using an iPSC hypercube. Furthermore, the parallel LU factorization implementation using factorization path scheduling was found to perform significantly better than levelwise scheduling. The maximum speedup of 2.08 was obtained by using four processors on the 494 bus system. The efficiency at maximum speedup was 52.1%
