Abstract

In this short note we describe some of the problems we have encountered on implementing the R-Matrix codes of Berrington et al. on the CRAY-1. In particular we consider the calculation of R-matrix angular integrals which as currently implemented are not vectorizable. Since this section of the code is sandwiched between highly vectorizable packages a bottleneck occurs. An alternative algorithm to circumvent this impasse is suggested.
