Parallel Gaussian elimination using OpenMP and MPI
S.F. McGinn, R.E. Shaw · 2003
In this paper, we present a parallel algorithm for Gaussian elimination: in both a shared memory environment using OpenMP, and in a distributed memory environment using MPI. Parallel LU and Gaussian algorithms for linear systems are studied extensively, and the the results of examining various load balancing schemes on both platforms are presented. The results show an improvement in many cases over the default implementation.
