There is a 15% win with the latest ATI sdk 2.3 and driver 10.12, but i don't know if this is the sdk or the driver which give me the win, because i first install the sdk and it needs the 10.12 driver's version to work.

OK, a new version, 0.1.0-beta, is out. Major changes you should notice:

- It only runs on GPUs.


Nice, i couldn't use my gpu in boinc with the previous version.

This app_info works for me, but i'm not sure it will for everyone.
