Catalyst 12.4 and Lunatics 6.10 (ati13ati)

Not entirely the same problem as yours but a problem surfaced shortly after the Catalyst 12.4 upgrade. For starters, I'm running an I5 2400. All four Cores running @ 100%.

Here are the oddities post Catalyst 12.4 upgrade.

1. BOINC is only requesting new tasks for CPU and I'm on my last AP. The rest are CPU WU's.
2. On occasion, the GPU would run on zero load. I know this is a known bug and the fix is to suspend/resume work, but it is more evident now.
3. If all 4 CPU Cores are crunching + 1 GPU supposedly crunching an AP, the usage goes to ZERO and becomes slow as dirt.
Fix: Modify app_info and dedicate a FULL Core on the AP. I did this on the x86 and 64 configs(See below)
<avg_ncpus>1</avg_ncpus>
<max_ncpus>1</max_ncpus>
4. With all 4 CPU Cores Crunching + 1 GPU MultiBeam Task also unloads the GPU.
Fix: Run at least two instances to load work the GPU.
Note: Just by choice, I never had to do this before

Stick - Have you tried suspending work > shutdown BOINC > restart BOINC > resume work?

Before I forget to mention, I have also attempted to roll back my Cat install only to find myself going through all this pain. I never had to with my previous NVIDIA card BUT I made this choice as I noticed that RADEON cards consume less electricity.

You say you upgraded to 12.4

Did you
1) Uninstall all your ATI drivers using the ATI express uninstall?

2) then use driver sweep to get the rest of the drivers that the uninstaller missed?

3)restart the computer?

4) then install the 12.4 drivers?

these steps must be followed to insure the correct removal and installation of the new drivers and for the Lunatics apps to process using the correct drivers

Stick - You just solidified my theory and after hours of banging my head on the wall. I will revert to 12.1 or even earlier this evening as time allows. I rolled back to 12.3 last night to no avail. Thank you for this bit of info btw! I'll give it a try and add some useful info to this post to share with my fellow crunchers. I am inclined to say the issue is not with Lunatics (been running on both NVIDIA and ATI as I tested both in the last month nor BOINC 7.025 but on the new Catalyst drivers. Anyone, feel free to correct my assumption on this.

The more accurate info I could get, the better as I don't plan on wasting my time tinkering with different combinations. It's growing pains I guess with the ATI world unfortunately...

Stick - if you wish to uninstall and reinstall Catalyst in a very clean way so you can switch to other versions, follow these instructions.

In addition, per Skildude's suggestion, install and run driversweep while you are in SAFEMODE: http://phyxion.net/item/driver-sweeper.html

I just remembered that I had to reinstall the AMD APP SDK found here which installs and may fix any OpenCL related issues you are having. By default, the cards run on OpenCL 1.1 but the AMD developer site released OpenCL 1.2 beta

Install the AMD APP SDK and choose your flavor, found here:

Here's a question we should have asked and I will now since I noticed what your GPU numbers are.

Is this a laptop GPU?

that GPU only has 384 MB available and I'm betting that shared. I have an HP laptop that has a 512Mb GPU and it is very slow. I wouldn't expect much out of your laptop GPU though you shouldn't be restarting drivers etc.

Have you ran GPUz to see if it is OpenCL and which version of OpenCL it is compatible with.

I'll check to see what ATI driver version my laptop is running. I've not updated it since it was working fine out of the box.
