The WebCL API is designed with security as a primary requirement. The Validator will enforce compliance of WebCL kernels with the defined WebCL language restrictions, and prevent out-of-bounds memory accesses. The WebCL kernel Validator will enforce out of bounds memory protections and will perform syntactic validation of WebCL kernels. The WebCL working group received five proposals, in response to the WebCL Validator RFQ. Vincit was selected to implement the WebCL Validator. Initial design discussions have started, which will be followed by development. All discussion and development will be done in public on firstname.lastname@example.org, and the project will be set up as open source.
