Albert@home is still an unofficial, non-public test project. Don't expect anything to work here. The only type of work Albert@home is currently sending out is for a highly experimental BRP4 OpenCL application.

Great, will expect doom and hell-fire. :D

Ok, so here as well, something breaks the signature. Enigma has the same problem.

There is no option in the preferences to select ATI graphic cards so the OpenCL will only be done with Nvidia at the moment.

Thanks for reporting. Although I think due to the way this setting is handled internally you shouldn't be able to opt-out of ATI 'work' right now.

Anyway, we'll add this.

Honestly I don't care much about sigs at all (I usually view posts w/o sig), and in particular on Albert. This is about the last thing I intend to test here.

The problem may occur because Albert doesn't export any stats, or something else.

Can you edit your preferences and set the signature again from scratch?

BM

Nah, that doesn't fix it but as you said, it's not a priority. The infinite work duration tasks that are sent... now that's another thing. ;-)

Although I think due to the way this setting is handled internally you shouldn't be able to opt-out of ATI 'work' right now.

Actually, that is possible with the <ignore_ati_dev/> option in the clients that can do that, and possibly with the <exclude_gpu/> option in the latest test clients.

Then it'll just do:
2011-11-01 05:13:40.7956 [PID=8972 ] [version] Checking plan class 'ATIOpenCL'
2011-11-01 05:13:40.7956 [PID=8972 ] [version] No ATI devices found
2011-11-01 05:13:40.7956 [PID=8972 ] [version] [AV#443] app_plan() returned false
2011-11-01 05:13:40.7956 [PID=8972 ] [version] Checking plan class 'NVOpenCL'

2011-11-01 05:13:40.7956 [PID=8972 ] [version] [AV#440] app_plan() returned false

But really, the BOINC back-end code should self-detect whether an ATI application is available in http://albert.phys.uwm.edu/apps.php and then automatically enable the "Use ATI GPU" preference. Apparently it doesn't work yet with your used version of the back-end and OpenCL applications.

Yah, we didn't look into that clever piece of code when we set up the plan classes. It did only work if your plan class name contained the string "ati" (lowercase).

Nothing but Computation errors so far on the OpenCL Wu's after just a few seconds. Tried 11.6 & 11.9 Drivers 5850 & 5870 Cards ...

The Linux App appears to work, at least on one of our machines.

I guess this is on Windows, where we are observing the same errors. FWIW the App works when running standalone, it crashes only when running under the BOINC Client.

How do you run the app stand-alone? It's not an executable.
It's called einsteinbinary_BRP4_1.09_windows_intelx86__ATIOpenCL ... no .exe Could that be the problem?

OK, I got the new AtiOpenCL app 1.11, got a bucket load of work for it as well, but it doesn't start. I even suspended all my other work and still the OpenCL tasks didn't start.

So I have reset my preferences, set them back to use both CPU & GPU. Doesn't matter. I took out the <exclude_gpu/> option from cc_config.xml as it clearly didn't work yet, but that doesn't matter either.

Now I am confused. :)

I'll post updates as processing continues/aborts/etc.

Hmm, OK, so all that work mysteriously ran and erred within seconds. Th error is still the same as with 1.09

My system has gone through several reboots yesterday, prior to it attacking the 1.11 work.

Great!

Status update:

Currently the Mac OS ATI App appears to be the only OpenCL App that's working properly:
* Windows OpenCL Apps still crash very early when running under BOINC
* The Linux OpenCL App crashed after 6/8 (on our machine), probably due to a memory access problem
* NVidia OpenCL App run but give way wrong results, possibly originating from the same memory access problem

We've disabled the Apps we know to give unusable results, will push out new Apps when ready for testing.

CPU results are still helpful for comparison.

The "zero flops" / "negative FLOPs left -1.#IND00" issue that occurred for CPU plan-class Apps with recent Clients should be fixed now.

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.

BM

I got the infamous "GPU type not found in init_data.xml" errror with the recommended BOINC client version 6.12.34. Then I decided to update my BOINC client to version 6.13.10 (pre-release).

Now the "GPU type not found in init_data.xml" error is gone, but the computation ends with an access violation, see here.
