Ok, we could finally track down and fix the problem. BOINC 7.0.11 contains the fix.

I run SETI today and I tried to run on both my ATI cards 5850 + 4850

and I get (schedular wait) after 25seconds of runtime on the 4850 card

I upgraded to BM 7.0.11 and I still have that message.
I read this thread and thought that maybe the BM was the problem here.
It can be other things though.....
I have succesfully run SETI on both cards before which BM I used I don't remember.

I need more details:
- You forced BOINC to use all GPUs via cc_config.xml?
- So our app works in your 5850?
- What's the total RAM of both GPUs?
- What SETI app? CAL or OpenCL?
- Did you run SETI and E@H at the same time?

more details.
-yes
-yes your app works with 5850
-5850(1gb), 4850(515MB)
-SETI app OpenCl MB version .390 for HD5xxx ATI cards
(I have completed tasks on them both earliar).
-Only SETI on both GPU's

-SETI app OpenCl MB version .390 for HD5xxx ATI cards
(I have completed tasks on them both earliar).

You can't use the 5xxx app on a HD4850.

From Lunatics Windows Installer v0.39 release notes:

ATI MB apps - upgraded to r390

We offer the application in two different variants, depending on card:
plain - for most HD4xxx owners and those with HD5xxx and HD6xxx cards who
suffer from driver incompatibilities.
HD5 - for most if not all owners of HD5xxx GPUs and HD6xxx GPUs.

The ATI MB application will not work on ATI cards with workgroup size 128 (e.g. HD43xx). To check workgroupsize run CLinfo, downloadable (at present) from {http://boinc.berkeley.edu/dl/clinfo.zip}
If you have problems running the HD5 flavour (anything from reduced performance to BSOD), you should run the plain variant.

The recommended apps (r521 for Astropulse, r390 for MultiBeam) need OpenCL support from the ATI driver - for recent driver versions, look for a driver *with* APP or OpenCL listed. For compatible drivers see http://support.amd.com/us/gpudownload/Pages/index.aspx
For cards, see hhttp://ttp://developer.amd.com/gpu/AMDAPPSDK/pages/DriverCompatibility.aspx
On most systems GPU-Z (see above) will tell you if your setup supports OpenCL.
Minimum required driver: Something that is OpenCL capable. You can check with GPU-Z (see above).
Catalyst 10.7b with SDK
Catalyst 10.10 Accelerated Parallel Processing (APP) Technology Edition
The following drivers are known to be incompatible with the app:
11.10 and 11.11.
On some drivers the app shows increased CPU usage.

For cards without OpenCL support (from HD2xxxx on) use the 'hybrid' r453 Astropulse application. NB this is a combined CPU/GPU application and will only use the GPU for some of the calculations, while doing the rest on a CPU core.
Minimum driver version Catalyst 9.x.

NB using this installer will give you arbitrary default cmdline parameter entries.
If you are already running ATI applications: Make a note of what numbers you are using to be able to restore to those values PRIOR to running the installer. This also applies to setting the <count> variable according to your -instances_per_device variable for multithreading.

The Hybrid AP application uses about 80% of a CPU core and does only about 20% of the calculations on the GPU. Parameters have been choosen to reflect this usage. However present BOINC can not reserve '0.8' of a CPU core and therefore reserves none. This means your CPUs will be overcommitted and runtimes and DCF will suffer. You do increase the overall output though.

I know. But I have done it.
It was some time ago so really didn't memorize which driver and config I used.
but yesterday I downgraded ATI driver to 11.9 which I thought I'd used.
It was before you taught me to use exclude in cc_config.
I have never before seen the (schedular wait) message until yesterday.
I read your thread today and thought that maybe the error comes from BM 7.x.x

Before I used to get errors when running HD5 on the ATI 4850 card except in 1 config that allowed med to run SETI ATI_HD5 on my 5850 + 4850 with success. I am very sorry I can't remember the exceact config.

When reading your thread I thought that BM 7.x.x could be the cause of the schedular error.

It can't be done........but i've done it...

-5850(1gb), 4850(515MB)

Well, I suppose 515 MB is right around what our app currently uses (we set the requirement to 490 MB). Which of these cards feeds your desktop? If any, is it multi-headed? Anyway, the app doesn't start since BOINC determines that the GPU in question doesn't have enough free/available memory.

-Only SETI on both GPU's

No, I wanted to know whether you ran any other GPU app while you tried to run our app.

I have tried albert on my 4850 before with no luck.
app works fine with 5850

I hav'nt tried on my 4850 since you in earliar threds have told us to be pationt with 4xxx cards.
Shall I try again on my 4850?

And I have successfully run SETI app .r390 ATI_HD5 on both cards 5850+4850 at the same time with sucess before. Now with BM 7.0.x I get "schedular wait" message.

I saw your thread and though that "schedular wait" had to do with BM 7.0.x to do.

and the correct number for ATI 4850 should be 512MB not 515MB , i typed wrong there.

5850 feeds my desktop
4850 is connected to TV via DVI-->HDMI adapter

Upon startup BOINC will detect if the GPU is OpenCL capable, which driver it's using and how much memory is on the GPU and what is available. Would you mind exiting BOINC and restarting it, then post those lines about your videocards?

I mean these ones:
18/01/2012 19:52:15 | | ATI GPU 0: AMD Radeon HD 6800 series (Barts) (CAL version 1.4.1646, 2048MB, 2015MB available, 2400 GFLOPS peak)

Hmm, that might be the problem....
