A program system for ab initio mo calculations on vector and parallel processing machines I. Evaluation of integrals

Abstract We present a program system for ab initio molecular orbital calculations on vector and parallel computers. The present article is devoted to the computation of one- and two-electron integrals over contracted Gaussian basis sets involving s-, p-, d- and f-type functions. The McMurchie and Davidson (MMD) algorithm has been implemented and parallelized by distributing over a limited number of logical tasks the calculation of the 55 relavant classes of integrals. All sections of the MMD algorithm...
