To vectorize or to ''vectorize'': that is the question. [CDC 7600 and STAR-100]

OSTI ID:7311468
Large computer codes can benefit from vectorization in two ways. The first is an increase in running speed, and the second is more transparent and orderly code structure. However, not all operations in a large code are vectorizable in the usual sense. The scope of vectorization can be expanded on both the CDC 7600 and CDC STAR-100. A general discussion of the considerations required when constructing a vectorized code is presented. The characteristics and performance of a representative set of vector subroutines for the CDC 7600 are presented. These subroutines allow for a much broader definition of vector operations, and a single coding example serves as an indication that the concept of vectorization can be greatly expanded on the STAR-100. 1 table.
