In the 1980s, super-computers looked like what you see in the image below. The semi-circular shape of a Cray was synonymous with super computers in the 80s. That was just what a super computer looked like.
What does this bygone era of supercomputing have to do with RISC-V? You see, Cray computers where what we call vector processing machines. Something that has long been considered a relic of the past.
Yet RISC-V is bringing Cray style vector processing back, even insisting it should replace SIMD (Single Instruction Multiple Data). Heresy?
