Jim Radigan and I recorded a session for Channel9 last week, as part of the “Going Native” series. We describe the “auto-vectorizer” – a neat feature in the VS11 compiler backend that analyses loops, in regular, unmodified C++ code, and generates corresponding vector (SIMD) instructions: tight loops using float or int can run up to 4x faster. The video has just “gone live” at:
nice feature, that I can use in production in some years... in other words: "We need XP-Runtime support"!!!
VS11 is *very* interesting except for the lack of Windows XP support. Please have a post on this decision, and if it will be restored by RTM.
Great I can't wait for WindowsXP support to test this feature out on some real pice of software.
I love VC11, those that are wondering about XP targeting support, I'm doing a series of blog posts at SupportXP.com - I'm about to post a very revealing one.
This is all just a tease... I just wish I could use it. But, alas, I have real paying customers to support that require Windows XP support. Sigh... hopefully MS will figure out what a massive mistake this is to not support XP.
Funny how I still don't know how to use auto-parallerizer after watching the video. The #pragma parallelize just doesn't work: I get a compiler warning, and the video doesn't say anything about how to use it.
