Abstract

In this paper, we present an OpenMP parallel preconditioner based on ILUPACK. We employ the METIS library to locate independent tasks which are dynamically scheduled to a pool of threads to attain a better load balance. Experimental results on a shared-memory platform consisting of 16 processors report the performance of our parallel algorithm.
