Maron, N; Sutherland, G G

This report discusses an AP190L array processor (manufactured by Floating Point Systems of Beaverton, Oregon) interfaced to a PDP-10 (Digital Equipment Corporation, Maynard, Mass.). After AP software installation, an analysis of the overhead was performed. The results of these measurements and some conclusions are presented. An AP monitor and software interface were written to minimize the overhead from the PDP-10. A vector extension to the FORTRAN language called FIVE was developed to increase user access to the AP. Some of the problems associated with defining and implementing FIVE are discussed. Its successes and limitations are reviewed. 2 figures, 2 tables.
