I read an article that GPUs are the future of supercomputers. I would like to know which programming languages are used for programming on the GPU
OpenCL is an open and cross-platform solution that runs on both GPUs and processors. The other is CUDA, which is built by NVIDIA for its GPUs.
HLSL, Cg several others
CUDA has quite a few language ports .. http://en.wikipedia.org/wiki/CUDA
