Abstract

This paper allows L. Lamport hyperplane method modified for improvement of the temporal data locality. Gauss-Seidel algorithm optimized by modified hyperplane method is faster than non-optimized in 2.5 times. This algorithm was paralleled by the technique of data placement with overlaps and we have got the speedup in 28 times on 16 processors in comparison with the non-optimized sequential algorithm.
