ATI OpenCL MultiBeam app (rev177)
Raistmer:
App requirements (the same as for released OpenCL ATI AstroPulse):
ATI Stream SDK 2.2 and higher (current version is 2.3) installed, Catalyst 10.7 and higher, HD4xxx(look know issues for more detailed info) and higher GPU.
EDIT: With latest Catalyst (10.12 APP) drivers SDK is unneeded.
Command line parameter that application supports
-period_iterations_num <N> splits single longest PulseFind kernes call on N calls
-period_iterations_num 1 (default value)
If you see lags in GUI or even driver restarts - add this parameter with value >1 (integer numbers).
-instances_per_device <N> allows to run N app instances per single device
-instances_per_device 1 (default value)
-hp will instruct application to rise its priority class to high. Useful when host under high non-BOINC loads. Also useful if BOINc client itself imposes high load on CPU.

Known issues:
- App will not work correctly with HD43xx GPUs and possibly other models who have max workgroup size of 128 instead of 256 (this can be checked with CLInfo sample from SDK)
- Double check if your config (GPU+driver) has OpenCL support in case of mobility GPU. Ask ATi for OpenCL support if not.
If you want to use few app instances per GPU change -instances_per_device param value and don't forget to change <count> field in app_info too to inform BOINC.
-Currently HD5 version only partially compatible with HD6xxx GPUs, probably, due to unmature drivers. It tested as working on HD6970, but there are sporadic driver restarts possible.
Also, there is additional binary placed in archive: MB_6.10_win_SSE3_ATI_HD5_r177.exe
It uses same CL file as usual version and designed for HD5xxx and higher GPUs. I would like to say great THANK YOU to SubSpace who provided countless profiler data from his HD5870 while I worked on HD5xxx kernels.
I have no HD5xxx-compatible hardware and w/o his help this secondary build hardly appear.
Also, I thank all alpha and beta testers who took participation in app checking and whole Lunatics crew for continuous support.

Snif :(
Found out that the ATI 4550 has a Max Workgroup size less than 256...

ERROR: clgetDeviceInfo(-30)
--- End code ---
Could this be another 'friendly' behavior between Nvidia and AMD?
Raistmer:
Max workgroup <256 issue will be fixed in next release.
About NV/ATi interoperability better to write on ATi (cause CLInfo is ATi stuff) forums. It's their job to fix.
I created thread on ATi forum: http://forums.amd.com/devforum/messageview.cfm?catid=390&threadid=147129&enterthread=y

Please, try to run modded CLinfo version attached to this post
