Can somebody check my errored wus and tell me how to proceed?
The other FGRP are on hold.
Two are looking like one BM bug which I reported and which I at least thought was fixed. Continue to run after completion. The CPU time is as short as the other errors. But I suspect BOINC didn't notice it.
Too tired right now to search the logs.

My BM start up info:

Well I think Steve has a point: If it is possible to deselect something then it should work. Otherwise it is confusing.
If the project don't want one to bail out of one search or another then the deselection should be disabled.

My understanding is that their CUDA is that good that openCL is at least sometimes slower on NVIDIA.

Please ignore my errored wus. I suspect my machine.
I had have that sometimes already with GPU apps.
At the same time I got SETI GPU errors and did a reboot as soon as I saw it.
Since then all is completing OK again.

Here the host error list: http://albert.phys.uwm.edu/results.php?hostid=1768&offset=0&show_names=0&state=5&appid=
All completed with exit code 194. All reported during 6th of Januray 2013.

Hi all!


With the help of your continued support, we were able to put the ATI/OpenCL app into production on Einstein@Home today.


http://einstein.phys.uwm.edu/forum_thread.php?id=9446

The apps are the same as used here, but note that the minimum BOINC client version was again increased to 7.0.27 (the most recent development version atm).

We will continue to improve the app so that we will again need beta testers at Albert@Home in the near future, but just now you will probably want to scale back the work at Albert a bit and throw your ATI-cards on the Einstein@Home production project.

Thanks again,
HB


That sounds great. You will cancel the unsent WUs?
Then we could just keep our machines polling the servers and will get new work and apps as soon as you have them.

So, finally catched a running task. HD5450 1gb memory max workgroup 128.
Memory use as per GPU-Z: 416 dedicated, around 70 dynamic. GPU load 96%

I have my older task done but it is still running. On trying to save all Messages to Memory to dump them BM is hanging again. Will report via Alpha Email list.

I have a 5450 but not yet the new app. SETI is right now on the GPU. There were some Ghosts wu lingering in my account so I allowed work to get them going. Sometime tomorrow maybe I will pickup new work here.

Hi,

I have two more errornous wu: http://albert.phys.uwm.edu/result.php?resultid=201372
and http://albert.phys.uwm.edu/result.php?resultid=201360

They have both the same exit code: [23:54:11][5900][ERROR] Error during OpenCL kernel setup: PS_R3 (error: -55)
[23:54:11][5900][ERROR] Demodulation failed (error: 2019)!

It is a bit different from my last failure. I just told BM to copy all Messages in case you need more info. Hope it works, atm BM is hanging and using one full core and around 700mb memory........

EDIT: Looks like I need to kill BOINC. Still stuck. The export did not happen. Which was that file where the messages are safed?

EDIT 2: So it was 'only the Manager that crashed. When I start BoincTask it told me that 4 tasks are running.........Somebody know an AddOn which is saving the Messages to a file outside BOINC?

I got one computation error. Propably it has something to do with my reboot yesterday.
I had one also with WCG, that was the reason for the reboot.

For me the new app takes a full CPU core when it is running. Is that by intention?


Hi!

This will depend on the driver version you are using, e.g. you can see from the screenshots posted here that this is not the in general the case for this app.

Cheers
HB

I was not exact enough in my statement. BOINC reserves a full core. '1 CPUs + 1 ATI GPU' and as I understand it that should not be the case.

Here one log snippet: 03.05.2012 22:25:33 | Albert@Home | [rr_sim_detail] 339385.57: starting p2030.20110421.G41.06+00.53.N.b6s0g0.00000_1448_2 (1.00 CPU + 1.00 ATI)

Oh, driver version 12.3 as far as I read it there that high CPU usage is solved.

I accidently reset Albert so my WUs are gone. Up to now they were not resend.
I thought that resends would even then happen when there is no work requested by the client.
I have still one SETIbeta running high priority on the GPU. Is that the reason?

Post:
I did only now realise that my card is not supported because you demand a min workgroup size of 256.


We don't, we just set a preferred value. If your GPU doesn't support it, the value is dynamically adjusted accordingly.


Cheers,
Oliver


Ah, that sound good. but please have a look at this result, because I don't see an indication that the work group size is adjusted.

Another point is this: [04:23:10][4764][INFO ] Checkpoint file unavailable: status.cpt (No such file or directory).
------> Starting from scratch...
NOT only at the beginnig of the WU. But after nearly 2 hours runtime. Is that the app or is it BOINC?

I have 128. HD 5450.

Can you lower that? Otherwise I will stop crunching with my GPU here for now. Raistmer is waiting for more results over at SETI Beta.

Oh, and the long runtimes which Ageless has are normal to me. I will set NNT to other projects to see if the times go down when my tasks run in one go.
