Look here for opencl on mesa/gallium (examples at the bottom of the page):
While those worked for me (reported succcess, the GPU was reset after each test (gpu hang for more than 10000 msecs dmesg error). Maybe they are designed to be run without an X server.

I also tried the opencl examples linked in the wiki, and about 1/3 of them fail :/
How did you get them all to pass? Did you run them without X?
Also note that opencl/llvm git are quite unstable on mesa. I pulled the latest git (it said version 3.5svn) of llvm and clang, recompiled mesa and x restarted when i started libreoffice after a few seconds. After restart i observed that glamor wouldnt work anymore and x was started with exa rendering despite having explicitly set glamor in the xorg.conf. It seems that it started, crashed and started automatically again with auto settings which in my case its exa. Tried restarting the lightdm server a few times, but every time glamor crashed. I didnt have the time to mess around so i recompiled mesa without llvm which works with no issues.
So dont get your hopes up, opencl/llvm is very much a work in progress prone to breakage if you use the latest version with the latest features, dont try to use it for anything serious ATM.
