Cross-platform interest in WebCL is expanding with support for Firefox, Chrome as well as Safari. WebCL provides a tremendous opportunity to exploit parallelism on client-side machines. Thanks for to Antonio Gomes (Twitter @tonikitoo) who brought the Safari webkit-webcl implementation to our attention!
The SMAST Computational Laboratory (CMLab) at the School for Marine Sciences and Technology at UMass Dartmouth wrote a nice post “Tinkering with WebCL” that will help Safari users try out WebCL. Alternatively can go directly to the webkit-webcl GitHub repository, or WebCL on Google Code.
