Message 24277 - Posted: 5 Jun 2009, 16:50:03 UTC

I detached and reattached my PC, with the AGP HD3850, to run the WUs on it's CPUs.

I now have 12 _3s_2_ WUs to crunch. So, there may be a few of thse around still.

I only moved to this about an hour ago, so when this picks up new work I will look see if I only get the _1s_2's and the _2s_1s and _2s_2's first before moving back to the GPU.
Go away, I was asleep

Message 24279 - Posted: 5 Jun 2009, 17:17:59 UTC

Unrelated to the 3s workunits, I've noticed some odd behavior since updating my BOINC client to version 6.6.31. When I get some work from here on the ATI app it sits at ready to start instead of beginning immediately as it used to. I have to pause / resume the other project in progress for it to begin working GPU tasks in parallel with other CPU project work. Re-installing the ATI app did not fix the problem. I'll watch how it behaves for a little while and may have to roll back to an earlier BOINC version. I've left the supplied app_info.xml as default and it's worked fine in the past. Perhaps it may be necessary to specify some values now.

Message 24281 - Posted: 5 Jun 2009, 17:40:23 UTC - in response to Message 24278.  

Gipsel got it fixed with version 0.19f

I will make a link out of it.
Version 0.19f of the ATI GPU application
is ready for download. Besides the fix for the three stream WUs it reports now the GPU time as WU time.

It was a really absurd bug, a missing line break in the GPU assembly (I edited the assembly after protyping it in a high level language). Because offline tools compiled it without problem (the compiler embedded to the graphics driver is obviously pickier) it was a bit hard to track that down in about 40kB assembly. But it works now.

Yes! thank you.
You guys are just great and second to non in the BOINC community.
Apparently you and the guys at Stanford are the only ones that know how to make programs that can put the ATI card to good use.

THANK YOU ! Cluster Physik, you are doing a Great job with the ATI Apps !

I wish my other projects like Einstein would implement ATI instead of this
focus on Cuda only nonsense.

If you look in the result, it shows it as Invalid. Why, I don't know.

Me either, I'm keeping an eye on it for a while to see if any others do the same. That's the first invalid unit i've had here.

Someone mentioned that the new 0.19f app runs the GPU a little harder and a little hotter. Are your fans clean?

That was related to the new wu's and the fact that 2 months have gone
after the message "Almost there!" on the 'Milkyway@Home for GPUs' page
where the GPU application and discussions regarded that should take place.

Yes! Very much so.

Last week I was suffering overheating, and stripped down, removed PCs to outside and compressor cleaned all machines and the dust bunnies. The only PC with a MW compliant GPU had the GPU removed from the socket and separately cleaned.

Interestingly, the PC is running just as heavily loaded now (98%), but the GPU temperature has dropped back to a normal (65C from 72C) and the GPU fan load has dropped to 47% from 55%.

Perhaps it's the cooler weather.

Yes, the fans are clean. One is a recent build and the other was just changed over into a new case and everything was cleaned before installing. Under load the cards are reporting temps of ~75C. Neither card is overclocked. Both systems are in Antec900 cases. Plenty of airflow there :-).
I had several more return as invalid overnight. I didn't do a reboot after going to 19f yesterday at 2230. I just rebooted both systems at 1400 UTC today. I'm going to watch them for a bit and see if that makes any difference.

<edit>
Reboot made no difference. Still getting the occasional invalid result. Is anybody else having the same problem? I might suspect it was a computer issue if it wasn't happening on both systems.

You made me look at my only GPU driven rig, and I am getting the odd invalid results as well. Three to be precise since UK lunchtime (13.30 - UTC+1). The successful WUs between them seem to be getting fewer before the next invalid result.

I wonder what ti is?
