ATI/AMD has released a GPU-accelerated version of the AMD Core Math Library (or ACML) based on the ATI Stream technology.
ACML-GPU accelerates certain routines in ACML by off-loading the computation to the compatible GPUs in the system. The library dynamically decides, based on the parameters passed to the routines, whether to run the computation on the CPU or GPU, depending on which processor will yield the best performance.
