I wouldn't expect OpenCL to work with clients older than 6.13.

Reminds me: we should probably add a client version restriction for these apps.

FYI, look at this: http://setiathome.berkeley.edu/result.php?resultid=2146353363

OpenCL platform detected: NVIDIA Corporation
OpenCL platform detected: Advanced Micro Devices, Inc.

and all other helpful info about OpenCL detection with BOINC 6.10.60

So? Just because Lunatics built a 3rd party application for Seti only that does the OpenCL detection, does not mean that the BOINC you're running does the OpenCL detection. This project uses the OpenCL detection built into the 6.13 clients to determine all OpenCL capable co-processors.

Added to that, as far as I know, the application here does not require an SSE3 capable CPU. The Lunatics app does.

They say most of your brain shuts down in cryo-sleep. All but the primitive side, the animal side. No wonder I'm still awake.

Ok. Fine. Clear.
I'll try 6.13 some later, despite the fact that I don't like > 6.10 interface without Messages tab.

Then keep the boincmgr.exe and boinc.dll from your present installation. You can run a newer client with an older BOINC Manager.

But the messages aren't gone, they are just in a window of their own, reachable by clicking advanced->Event Log, or pressing CTRL+SHIFT+E.

As for 6.13, do know that even the latest client, 6.13.10 is highly unstable. I have managed to get it to crash 3 times already by just running this project. The 6.13s aren't available for long time use, they're test versions on the way to BOINC 7.

FYI, we just updated the AMD OpenCL binaries for Windows, Mac OS 10.7 and Linux (all OpenCL 1.0, minimum BOINC version: 6.13.x).

Current status:
* Windows: finally works, no known issues
* Mac OS X: no known issues (10.7 support only!)
* Linux: might use full CPU core, please confirm

Thanks for testing!

Yes, look at that. v1.17 is finally running longer than 4 seconds. :-)
Still... not out of the woods yet. At 90 seconds now I have a computation error.

And now they all end with error at 43 seconds.

Thanks Jord! That's really helpful.

I need to change some settings as your GPU is not able to handle our current parallel thread block structure. I need to check the specs of AMD's GPUs again...

I'll deploy an updated binary as soon as possible.

Cheers,
Oliver

I rebooted, just to make sure it wasn't something stuck in my GPU.
After reboot, I first started GPU-Z, then BOINC. No load on the GPU. Tasks don't run longer than a minute so far.

You guys should opt-out of GPU tasks until the next version.

Oliver, Mac OS X 10.7 does OpenCL 1.1 already, for OpenCL 1.0 OS X 10.6 is also fine.

I know.

a) We have an OpenCL 1.1 version, but it would constrain the list of compatible GPUs.
b) 10.6 is buggy and Apple doesn't care about it, hence we can't support it.

Oliver

Hi guys,

Yep, you got the same device series (HD 4xxx) as Jord. The issue is understood and I'm working on a fix, but it's not that easy...

You guys should opt-out of GPU tasks until the next version.

We deployed updated binaries (v1.19) that should adjust dynamically to the specific hardware they run on. This should fix the issues you've encountered and ensure support for lower-end GPUs like the HD 4xxx series.

<max_ncpus>1.000000</max_ncpus>

The task is running, but going slowly. At present rate, with it taking 2 hours to do 22%, it'll take ~9 hours to do the whole 100%. A tad slow, when compared to a similar task at Einstein done on my CPU takes ~10 hours.

I've set BOINC to use 3 CPUs, leaving one open for the GPU and everything else non-BOINC.

You're mistaken, these are not similar tasks. If you want to compare GPU vs CPU performance you need to crunch a few of the tasks over here on your CPU. Also, the actual GPU performance varies quite a bit from the Radeon HD 4xxx to the 5xxx and the 6xxx series.

Some approx. runtime numbers:
HD 6970 (Windows): 1 hour
HD 6970 (Linux, no PGO): 1.2 hours
HD 5770 (Mac OS 10.7): 7.2 hours

You see that your 4xxx GPU blends in just fine...
