摘要

The NUMVEC FORTRAN library routine ICCG3D for the solution of seven diagonalsymmetrical linear systems, that arise from the seven point discretization of a partial differential equation over a three dimensional domain is described. 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.
