Title: Some parallel algorithms on the four processor Cray X-MP4 supercomputer

Conference ·
OSTI ID:551974

Three numerical studies of parallel algorithms on a four processor Cray X-MP4 supercomputer are presented. These numerical experiments involve the following: a parallel version of ITPACKV 2C, a package for solving large sparse linear systems, a parallel version of the conjugate gradient method with line Jacobi preconditioning, and several parallel algorithms for computing the LU-factorization of dense matrices. 27 refs., 4 tabs.
