It contains phpass, cryptmd5 and cryptsha256 formats. Performance is poor, but will be increased especially on amd devices in the next revisions and mscash2, cryptsha512 will be added. Patch can be downloaded directly from: http://openwall.info/wiki/_media/john/john-1.7.8/john-1.7.8-allopencl-01.diff It doesn't provide multi gpu support, and always uses primary gpu.
