Pipelined Vector Processing and Scientific Computation

Description
For almost two decades (1976-1993) technical-scientific high-performance
computing has been dominated by vector processing, pioneered by
Seymour Cray and his Cray Research Incorporated. This technology
is explained in detail, and the significant cost-performance advantages
are outlined. While parallel processing is more en-vogue today, and
in fact is dominating scientific computation since 1993, a comeback
of vector processing may be on the horizon due to the IBM/Sony/Toshiba
Cell processor being a parallel vector processor, and being the
highest-performance single chip available today.
