[New release] BRP app v1.22 feedback thread

(moderation:
Hi,
We just released BRP4 v1.22 which adds a number of improvements.
Notes:
* OpenCL GPU memory requirements reduced by 128 MB (to ~360 MB)
* Dropped support for OpenCL 1.0 GPUs (in favor of the above, OpenCL 1.0 only GPUs like the Radeon 4xxx are too slow anyway)
* More graceful OpenCL memory error handling
* Known issue: no OpenCL support for Mac OS X for the time being (we're looking into a potential Apple bug, no pun intended)
* CUDA apps are enabled again for the time being
* Input data download volume (per work unit) can be reduced by a factor of two (soon)
* Please use the latest Catalyst driver (>=12.1) and BOINC client (>=7.0.12).
Let's try and collect your feedback to this specific release (and this one only) in this thread.
Thanks,
Oliver

Just to be sure: By "latest Catalyst driver (>=12.1)" you mean "AMD Catalystâ„¢ 11.11 - Revision number 12.1" ?
I can't find any Catalyst 12.1 for Linux on the AMD site.

should we dump Wu's still using the 1.21 app? I've noticed a few inconclusives and errors on that app. not seeing any problems from other GPU projects

That's just because of AMD's sloppy web editing. The one you found is the 12.1 driver.

Depends on what errors you saw. If they are memory-related you probably want to reset your project. You'll be resent the same tasks but they'll be crunched with the latest app version which required less memory (OpenCL only).

Task comes in with

Task comes in with 300000000000000.000000 which tells BOINC the task is going to take 210 hours and a bit, so BOINC will run it for a long time in panic mode. Can we please get a reasonable fpops estimate, one that doesn't immediately throw Albert tasks in High Priority?
Are there actually tasks

Are there actually tasks available? I'm not receiving anything for my GPU.

you have to leave a cpu free otherwise it's unlikely to get work.

Freed up 2 threads out of 8 and still nothing. Still no work. I'm currently running Moo! so I suspended the project as well. No tasks.
RE: Are there actually

Yes there are and your config looks fine so far. Please have a look at the BOINC event log: did BOINC recognize your AMD GPU as OpenCL device? According to our logs it doesn't seem to be the case. You might need to reinstall the Catalyst driver. Also, remember to start the X server and make sure that BOINC can access the X display. If "clinfo" exists on your system you may use it to verify that your GPU is properly enumerated by OpenCL.
