Vectors are simpler and "rigid:" In article <1991May4.031835.7979@midway.uchicago.edu> rtp1@quads.uchicago.edu (raymond thomas pierrehumbert) writes: >Now, the $64 question: Why no supercomputer based on an >architecture for the processor like the RS/6000, BUT with >your extra $2M buying bandwidth to memory like the Cray's >(no cache)? 1) Few supercomputers exist. New architectures are expensive propositions. 2) Vectors were proposed in the 1960s by IBM, built in the 1970s by Cray and others. S-Scalar were not implemented until the 1980s. 3) Technological and economic factors play on any person trying to design and build a super. Do you want to build one? I didn't think so. Can I get my $64? Ain't hindsight wonderful? 8^) It's not only clear, but it's cheap.
