- acqq 11y agoIf you mean when it's fixed, yes. That's what I wanted to say. But I also wanted to mention that even the fixed width increases from time to time.
- TheLoneWolfling 11y agoNo, I mean with SIMT as well. And increasing the size of fixed-width operations from time to time does not help existing code.
- acqq 11y agoStill, having the fixed width allows you to optimize the existing code better than when you introduce the abstraction without the fixed width. See the shuffle operations and similar, which operate on the parts of the wide registers and which are actually needed for the real life optimizations to avoid expensive memory accesses and allow operating on the registers alone.
