If Stream processors are really GPUs, will I need to learn graphics programming to properly implement my application?
No. AMD along with the open source community are working to mask the GPU’s graphics programming heritage. This is being accomplished by our release of Brook+, the open source Brook compiler plus AMD enhancements geared directly at non-graphics stream computing, and AMD’s CAL — Compute Abstraction Layer. CAL provides high-level language access to the various parts of the GPU as needed.
