GPU update

A few updates in the GPU world for the last month:

• AMD released OpenCL SDK, bringing the Stream SDK 2.0 out of beta.
  
• AMD released mobile DX11 GPU's
  
• CUDA Database cracker for Oracle and Microsoft SQL was released, doing about 200 millions passwords / second.
  
• MD5 Crack, a brute force GPU-MD5 cracker was updated.
  

Tony Albrecht from Sony released his slides on Pitfalls of Object Oriented Programming, which describes how to write optimal C++ code. (I'm a strong believer in C++ for all problems). Tony demonstrates how to convert 'typical' C++ code for managing a scene graph into optimal code getting a 6x speedup from using a custom allocator to ensure linear SOA data, removing conditionals (doing more calculations since compute is faster than branch), flattening the scene hierarchy, and prefetching data. It's a great read! (a bit light on some details though!)
Finally, this excellent video of a DirectCompute fluid simulation was released by Jan, you can get the fluid source code from his website.
