OpenCL (Open Computing Language, a framework for writing programs that execute across heterogeneous platforms consisting of CPUs, GPUs, and other processors)

• http://en.wikipedia.org/wiki/OpenCL
• OpenCL includes a language (based on C99) for writing kernels (functions that execute on OpenCL devices), plus APIs that are used to define and then control the platforms. OpenCL provides parallel computing using task-based and data-based parallelism. Its architecture shares a range of computational interfaces with two competitors, NVidia's CUDA(Compute Unified Device Architecture) and Microsoft's DirectCompute.

GPGPU (General Purpose GPU)
