SIMULTANEOUS EQUATIONS ANALYZING COMPUTER BY RELAXATION METHOD

摘要

PURPOSE: To attain high speed and high performance by calculating the different variable of simultaneous equations by connecting plural calculating elements in the form of a ring, and transferring its own calculated value to the neighboring calculating element in this process. ;CONSTITUTION: The calculating elements PE₁ to PEN are connected in the form of the ring by the data line of a single direction so as to communicate with each other. This ring is provided with a gateway processor GE to communicate with a host CPU, and it executes the setting-up of the calculating element, the sending of a command and the judgement of convergence. In a specified step in the calculation of a relaxation method, each calculating element PE₁ to PEN analyzes different linear simultaneous equations respectively, and transfers an analyzed result to the neighboring calculating element. In the next step, the calculating element having received this transfer executes the analysis of a succeeding step by using the received analyzed result. Accordingly, high- speed relaxation method calculation can be executed, and besides, each claculating element need only have small traffic, and the analysis calculation of the high performance can be realyzed.;COPYRIGHT: (C)1994,JPO&Japio
