Very interesting show. It's always good to get more performance-for-free features tossed in.
I, for one, would very much like to see some special sessions taking a deep dive into the internals of auto-vectorization and the tricks used to vectorize code that doesn't obviously lend itself to that process. The nature of my work often presents me with loop dependencies that do not vectorize/parallelize well. Anything you can provide, either through uman communication or through tooling, to help programmers code in more readily-vectorizable styles would be of value too.
Whatever happened to project Phoenix anyway? We haven't heard of it in a long time. I assume it has been assimilated into other projects. We can see pieces of it in things like Rosalyn, but it seems like there was a lot more to it that hasn't popped back up.
