I think you misinterpreted what I said. I prototyped formerly in Python, and now with Ruby. I also do not chase down null pointer violations most of the time (except when debugging any CUDA exported functions that need speed).
Ahh, righto, sure did! Well then we agree. How do you like CUDA? We just took delivery on a 4xTesla C1060 box which I can't wait to check out. Sadly it's sitting in a closet right now because of departmental squabbling over who must foot the air-con bill when it gets plugged in :-)
I have a single C1060 on my desktop system -- it is the single greatest investment I have ever made. Granted, debugging CUDA is not great, but the for many things Thrust alone (http://gpgpu.org/2009/05/31/thrust) can make demolish any bottlenecks so you can get closer to your idea rather than spending all your time on metal. However, I have to play with OpenCL...especially now that OSX has built in support!
