Not to dismiss his points out of hand, but he is a chief at Nvidia, so I'd going to take his "multi-core won't work" statement with a grain of salt. SIMD and vector processors are great for some jobs, but certainly not for everything
- DannoHung 17y agoThey're great for a lot of things, I thought. I dunno, I do loads (haha, I just realized that's a pun) of work with stuff that uses SSE.
- habitue 17y agoOh yeah, SIMD/MIMD is indispensable, all I'm saying is that in the long term that's not going to suddenly solve every problem every time. There are a lot of intrinsically sequential processes and only so much parallelism can be extracted from any given problem. Personally, my guess is that eventually we will end up with a small number (maybe 128-256) of coordinator processors that are like current multi-core CPUs, and then a vast number of vector processors that it delegates work to.
