CSKYTI: An Out-of-Core Cholesky Algorithm Equation Solver (with Respect to Profile) for the Texas Instruments' Advanced Scientific Computer.

摘要

CSKYTI is an out-of-core profile approach Cholesky algorithm equation solver for large sparse positive definite systems of linear equations. CSKYTI is an adaptation of an existing CDC 6000 series program, CSKYDG2, for the Advanced Scientific Computer (ASC 6). The preprocessor program SETUP for CSKYTI was similarly obtained from CSKYDG2's SETUP program. This report documents a comparison of the performance of CSKYTI and its SETUP on the ASC 6 with that of CSKYDG2 and its SETUP on the CDC 6600 at DTNSRDC. It would appear that the ASC 6 requires double precision arithmetic to obtain the significance of single precision computation on the CDC 6600. Even so, the ASC 6 was found to be fast compared to the CDC 6600. (Author)
