If you look in the PLINQ samples in the December 2007 CTP, you'll see a parallel implementation of Luke Hoban's LINQ ray tracer.  The sample parallelizes the ray tracer by changing very few lines of code.   Luke's original query started as follows:from y in Enumerable.Range(0, screenHeight)For our sample, we've changed that to...

Community Technology Preview (CTP) releases from Microsoft typically provide early looks at the technologies a team is working on.  Frequently, CTP quality is nowhere near what folks might expect from Beta releases and the like, and that's ok.  The idea is to give all of you in the community a look at what we're working on, giving ...

Software is headed for a fundamental change.  Over the last 30 years, developers have relied on exponential growth in computing power in order to dream big.  Your cool new application is too slow today?  No problem, just wait two years and everyone will have computers that run twice as fast.  But as Herb Sutter wrote, &...
