Abstract

In molecular orbital ab initio calculations, the two-electron integral calculation is the most computationally expensive part. With the increase in the size of the molecules, calculation of integrals will require a large processing power. Improvement in the calculation time of the two-electron integrals has always been a hot spot in this research field. In this paper, we have suggested a novel implementation of algorithm on a heterogeneous system of CPU and GPU. Trace based results show that the proposed implementation can gain significant performance benefits for the calculation.
