What is "webcl"

WebCL (Web Computing Language) is a JavaScript binding to OpenCL for heterogeneous parallel computing within any compatible web browser without the use of plug-ins. Primarily, WebCL allows web applications to actualize speed with multi-core CPUs and GPUs; this intends to make computationally intensive programs feasible in the browser, e.g. physics engines, canvas element and video editing. WebCL is designed and maintained by the non-profit Khronos Group. The completed and ratified specification for WebCL 1.0 was released on March 19, 2014.
