The SIGGRAPH conference was held in Vancouver on August 13. OpenCL was one of the topics discussed and the slides from the Khronos Group can be downloaded here.
Looking through the OpenCL BOF slides, four points caught my eye:
- AMD was the first company to support OpenCL 1.2, but Intel will be the first to support OpenCL 2.0. Their new Broadwell GPU architecture complies with the OpenCL 2.0 spec and AnandTech has a great article on it here.
- The presentation states that "The Future is Mobile" and I agree. But iOS and Android are nowhere near supporting the execution of OpenCL kernels. This is a shame, as many mobile GPU vendors are working hard to provide OpenCL SDKs and drivers.
- Version 2.0 of SPIR (Standard Portable Intermediate Representation) has been released. This format makes it possible to exchange (i.e. sell) device-agnostic OpenCL programs without giving away the source code. I need to learn more about it.
- OpenCL 1.2 was released nearly four years ago, but Nvidia still doesn't support it. And as I've learned from experience, they don't make it easy to get their OpenCL 1.1 library.
