I'm proud to announce the initial release (version 0.1) of Boost.Compute! It is available on GitHub and instructions for getting started can be found in the documentation.
Boost.Compute is a C++ library for GPGPU and parallel-computing based on OpenCL. There have been 292 commits by 4 authors comprising ~26,000 lines of code. I am very thankful to those who have contributed and would encourage any others who are interested to shoot me an email.
I look forward to any feedback. You can submit an issue through the issue tracker or contact me directly (email can be found in my profile).
