Large randomly sparse matrix vector products are important in a number of applications in computational chemistry, such as matrix diagonalization and the solution of simultaneous equations. Vectorization of this process is considered for the CRAY XMP, CRAY 2, and CYBER 205, using a matrix of dimensi
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-I. In particular we consider the calculation of R-matrix angular integrals which as currently implemented are not vectorizable. Since this section of the code i
## Abstract Several variants of standard algorithms for DNA sequence alignment have been implemented on the Cray Multithreaded Architectureβ2 (MTAβ2). We describe the architecture of the MTAβ2 and discuss how its hardware and software enable efficient implementation of parallel algorithms with litt
