What Kind Of GPU Are You?

In the old days, big computers often had some form of external array processor. The idea is you could load a bunch of numbers into the processor and then do some math operations on all of the numbers in parallel. These days, you are more likely to turn to your graphics card for number crunching support. You'll usually use some library to help you do that, but things are always better when you understand what's going on under the hood. That's why we enjoyed [RasterGrid's] post on GPU architecture types.
