It is a great joy to see this Astropulse application 555 whack these out in max 1 hour 45 minutes.
I am very sorry for my rude behavior when the 40 installer was released and there was no Nvidia app for astropulse.

Great job on all fronts.
LadyL and Claggy thank you for the 555 app

I am using Nvidia 266.58 x64 drivers
Can I go up to cuda 4 or do I stay at 3.2

I saw that 270+ does work

Just curious

Will those work to fix this on the ATI client as well? I don't understand why half of my WUs run normally and half of them crap out.

I'm having trouble finding any x41u reported results, can you direct me to some tasks ? thanks.

Probably my end then ;), My internet's doing freaky things tonight with all sorts of things... oh well, that I can look into later.

Worth a try. Looks like Something OS scheduling related has changed, so we may well be dealing with prioity issues all around.

What do you mean crap out? Error out? or just low GPU load?

Thanks,
nothing obvious except the one running longer for no apparent reason.

Wonder what the difference is between my machine, alpha testers & that machine. Well worth finding out.

Images all OK here too. John's most recent was http://62.131.164.180/seti/afterburner4.jpg - I don't know whether the IP address, rather than the more typical url-style, could have caused your problems?

It's doing the same thing as the CUDA clients, low utilization and dropouts. I linked some of the WU's above. I've since run some more, with the same results. A few go splat due to noise, about half run normally at 86-90% utilization and take a little over 3 minutes, and half show the same splotchy, terrible utilization as shown for those CUDA clients, and run several times longer than normal. At first I thought it was a VLAR issue, since I noticed it doing this on VLARS sent to my card, but now I see it's just doing it randomly on normal WUs too.

these ran normally

Thanks,
Can you jack up the cuda process priorities (with one of the tools mentioned) & compare ?

BTW: for some reason I'm having trouble getting to your images.

Jason


My bad. My firewall was blocking everything from Turkey on eastward. Made some changes and you should be able to see the images now.

I will try to boost cuda priorities tomorrow. If I remember correctly, Khangollo posted some info in a Linux related discussion about raising thread priorities in Linux so I will try the same with x41g on the Linux pc's

I think so. Will have to investigate the cable later today.

On the priority issue, playing with Fred's priority tool between regular below normal & normal does make a noticeable impact on GPU usage. Really wish I hadn't been pressured into dropping those priorities now, oh well, better put some command line options in the next build.

That's better!

OK, yup, looks like priority to me. Fred's tool seems to be working for me, raising the x41 processes to 'normal'. I'll jimmy some options into the next build somehow

There is a low ATI GPU usage Bug about, i have had it since Cat 10.5, ATI_HD5_ r374 and also on ATI AP apps since r521 all on my i7, But my E8500 when it had the HD5770 fitted didn't suffer from it,
Don't know if it's a driver Bug, an app Bug, a Windows scheduler Bug or what, I suspect it's an app Bug since PrimeGrid's OpenCl app hasn't suffered this on my HD5770,

If you suspend the task with low GPU usage, wait for it to exit, then resume you should get the GPU usage up again,

Don't forget that the priorities were dropped because some people want to use their computers for purposes other than BOINC, and have less than the latest and greatest hardware - then, screen lag and usability also matters. IIRC, you only raised the priority in the first place to ensure a level playing field in Beta testing with other players who were also gaming the priority arms race: x38g was also bounced from Beta into Release status at rather short notice.

Meh, if that's the case I'm not going to babysit the thing to fix a random bug that may or may not show up every 3 minutes. I guess I will stick with the CPU clients for now, and by the time I build a new Nvidia machine hopefully the issue there will no longer exist.

All true. I have to stop short of asking the 'victims' here for lists of all the programs & services they run. If they want regular full GPU usage, then for now they'll have to either:
- locate what's shoving the Cuda threads aside & stop the culprits, (e.g. BlackViper their systems)
- use priority tools such as those posted, or
- put up with erratic GPU usage

I'm still reluctant to add complexity to the X series with command line options, considering that its main successes are attributable to its simplicity. I feel left with no choice at this point to offer the option to these guys... For example Victor was borderline abusive over the issue,.

Well, we'll see how the best course reveals itself over the next week, as some GTX 680 related cosmetic fixes are incorporated also.

A minor addition to the v0.40 readme file can save a lot of dissapointment:

"For the best performance without compromising usability it is advisable to leave one cpu thread free by setting the option On multiprocessor systems use at most 75% of the processors. (for quadcores that is..)
Those who aim for the highest production should install a priority raising programme such as..."

Maybe - just brainstorming here - we ought to consider building something into the installer. We could have an option switch, or two versions, or ... whatever, let me sleep on it.

But if there was a choice of "built for comfort" versus "built for speed" - would that help people? I haven't yet seen Victor's comments (although I've asked him for feedback), so I don't know exactly what the problem is.
