Abstract:

The design of a special purpose computer to operate in parallel with a general purpose computer to accelerate the diagonalization of real symmetric matrices is described. The entire system operates in a configuration described as the Fixed-Plus-Variable Structure Computer Estrin, G., Proc. W.J.C.C., May, 1960, pp. 33-40 such that the same elements used for the special purpose computer may be reorganized for other problem applications. The Jacobi method of diagonalization and an available program utilizing an improved technique for its execution on existing computers are described. The bases of decisions leading to design of the special purpose computer are explained. The nature of the supervisory control, which coordinates the activities of the general and special purpose computers is detailed. The predicted increases in speed due to the organization and parallelism and then with the superimposed effect of higher speed circuitry are evaluated. Author
