SPARSE MATRIX CALCULATIONS USING AN ARRAY PROCESSOR.

A description is given of the applicability of AP-120B/190L array processors for solving large systems of simultaneous linear equations using sparse matrix techniques. These techniques are used in such diverse fields as structural analysis, chemical engineering, electric power network analysis, computer-aided network design, and physics. Several sparse matrix benchmark programs which have been written for the AP-120B/190L are described. Results of these programs are presented for various hardware configurations. Finally, the performance on sparse matrix problems of the AP-120B/190L is compared to that of large vector machines.
