This article deals with the problem of estimating the error in the computed solution to a system of equations when that solution is obtained by using Gaussian elimination without pivoting. The corresponding problem, where either partial or complete pivoting is used, has received considerable attention, and efficient and reliable methods have been developed.(More)
Chu, E., A. George and D. Quesnel, Parallex matrix inversion on a subcube-grid, Parallel Computing 19 (1993) 243-256. In this paper we propose a new medium-grain parallel algorithm for computing a matrix inverse on a hypercube multiprocessor. The algorithm implements Gauss-Jordan inversion with column interchanges. The hypercube network is configured as a(More)
