Parallel computing is the future.
By now the IT industry realizes that the limits of clock speeds have been reached. The new paradigm for the performance race is parallelization. Multi core CPUs have become mainstream but this is only the beginning. The new parellelization paradigm means performance increase by increasing parallelism, by increasing the number of cores.
GPUs already feature hundreds of cores. So GPGPU is simply the best installment of practical parallel computing that is available today. It is a solid investment in what soon will become mainstream.
With the industry wide supported parallel computing solution OpenCL, it is possible to unlock all parallel computing power. Not only that from the GPU. NVidia, AMD, IBM, S3, PowerVR and Intel all support OpenCL to provide access to their parallel computing hardware. Be it Graphics Processors, multi core CPUs or other architectures, OpenCL is the single most effective and future proof parallel processing solution available.
