A note on parallel matrix inversion (English)
0 references
Parallel inversion algorithms, based on Gauss-Jordan elimination, for general and symmetric positive definite \((n\times n)\) matrices are presented. Additionally parallel implementation issues are discussed. These algorithms maintain the same arithmetic cost and numerical properties of conventional inversion algorithms. The performance of the parallel Gauss-Jordan elimination inversion algorithm for general matrices and of the one-sweep inversion algorithm for symmetric positive definite matrices is presented, for distributed memory parallel computers, such as Cray T3E-600 and a Beowulf cluster.
