Abstract
The conjugate gradient method for solving the system of linear equations arising during a finite element analysis has gained renewed interest with the advent of distributed memory computers. In this paper a method will be described which minimizes storage by taking advantage of symmetry and sparsity and minimizes communication overhead by using asynchronous message passing. The data structure necessary to implement this procedure follows naturally frotn the finite element mesh. Test results show near linear speedup for a suflciently large matrix.
