Abstract

A parallel algorithm based on a recent high precision direct (HPD) integration method is presented and evaluated in this paper. A mixed fine grain and coarse grain strategy for parallel computing has been developed. Examples show that this method has good accuracy and that high speedup and efficiency are obtained. A hybrid form involving two types of coarse parallelisation has also been shown to have advantages when a Fourier series form of the HPD method is used and the number of processors is not a factor of the number of terms in the series.
