David Tarditi and Sidd Puri, scientists at Microsoft Research in Redmond, WA, USA, are creating some really compelling managed libraries that provide an elegant approach to writing highly parallel data intensive code. They basically hack the GPU to enable roaringly fast parallel computation. They call this .NET-based framework "Accelerator" and explain it in detail on Channel 9. Check it out and get the bits in your hands now. This is great stuff.
