In an attempt to undermine the belief that little software exist for vector processing Scientific Computer Systems Corp of San Diego claims that there are now more than 150 applications available that take full advantage of the high-speed vector processing capabilities of the SCS family of minisupercomputers. Roland Samuelson, applications marketing manager, notes that because of the SCS systems’ compatibility with the Cray X-MP instruction set and CTSS and COS operating systems, third-party software vendors are able to qualify application programs easily. This has enabled Scientific to increase the number of programs to over 150 from the 50 that were in the first edition of the SCS Applications Software Catalogue, which came out last June.
