Abstract: qThis document describes the NUMVEC FORTRAN Library routine ICCG3D for the solution of the 7-diagonal symmetrical linear systems, that arise from the 7-point discretization of a partial differential equation over a 3-dimensional domain. Use is made of the so- called MICCG-hyperplane method with scaled initial diagonal, 'Eisenstat's trick' and Cyber 205 sparse vector instructions. An example shows a performance of nearly 85 MFLOPS for this routine.qAbstract: aquot;This document describes the following NUMVEC FORTRAN Library routines (developed for the Cyber 205): MATMUL performs matrix- matrix multiplication on full matrices, by means of 64-fold unrolling in the usual vector update method; ...
