So you are saying the tasks keep running, when you start to use the system?
If so, what sort of installation did you do; a Boinc service installation, fresh installation or upgrade?

I would try setting the "While processor usage is less than" to 10%

So you are saying the tasks keep running, when you start to use the system?

Yes. Perhaps you missed my comment below the pic: "If I open BOINC in a small window and start Chrome in another (opens 15 tabs in about 15 seconds), BOINC's progress % never waivers. It just keeps on going."

If so, what sort of installation did you do; a Boinc service installation, fresh installation or upgrade?

Having uninstalled BOINC a month ago I downloaded a fresh copy (7.0.28).

I would try setting the "While processor usage is less than" to 10%

Did that.

I just finished a WU - no impact on performance. The current WU, though running 100% of the time, has no impact either.

Bonsoir tomba,
your processor is an Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz [Family 6 Model 26 Stepping 5]
(8 processeurs

I notice you let 100% of CPU usage allowed and 100% of processors/threads ?

You have only one GPU so you could set the CPU affinity for GPUGRID WUs in the task manager -> processes -> right click on the process for GPUGRID WU (acemd... for exemple) -> Define affinity -> select the desired cores you let the process use. Unselect others.
By default all cores are allowed..

For exemple let 4 cores for GPUGRID WUs in a total of 8 and observe.

By the way did you read my remark above about HDMI vs VGA ?

Regards

I would check that you don't have enabled "Leave Applications In Memory While Suspended" in the disk/memory tab. It could be causing problems if the tasks aren't terminated and left in memory, they are still active, somehow.

No. That option is not checked.

OK. Did that, though it seems he does not remember the affinity setting. Not good for unattended operation!

Not yet...

Since I restarted processing GPUGRID WUs, two have processed with no performance impact. One of them is uploading now. The third one that's just started has jammed the video brakes on, hard!!

Oops - my ASUS GTX 460 doesn't have a VGA port!

Are you running any CPU tasks on that system?

The recommended power setting is Prefer maximum performance.

If the first thing you do when you start using your system is to load 15 web pages, this probably doesn't give Boinc enough time to suspend the GPU task, which means unloading and writing it to disk (GPU tasks are not kept in memory). If the 15 web pages contain Java or flash then they are going to be resource (HDD and RAM) greedy.

I think this is a general Boinc problem (from legacy designs) which is being exasperated to some extent by task types (size), but largely other programs (browsers), hundreds of operating system updates/patches and of course drivers that are aimed at the most recent cards.

If you ran Boinc from another drive, it might help, but try to just give it 30sec before you open your browser.

Yes , but your monitor seems to have one.
You must use a DVI to VGA adaptor normally delivered with the card if you bought it new...!
So you will be using the one of the DVI output of the card plugged to the VGA input of the monitor through the adaptor .
You will of course need a VGA cable between the adaptor and the monitor... .

If the 15 web pages contain Java or flash then they are going to be resource (HDD and RAM) greedy.

But if BOINC is obeying my settings, in 15 seconds it must have time to at least stop the running WU before doing its housekeeping. No sign of it doing that...

Did that. No difference.

Seems to me that that some WUs obey my BOINC settings, some don't. Surely that points to a GPUGRID problem??

I'm now keeping a log of which WUs affect performance and which don't.

I have had the same problem (NATHAN units only). They can not run on GTX460 while you're using computer without making computer nearly useless.

I would like to say all other units run fine!

Sorry, but this is not true for me.

I used to have a GTX460SO and a GTX460OC and ALL WUs were running without loss of video performance even when watching a movie and at the exception of playing some games : in this case I simply have forbidden GPU crunching in cc_config.xml when these applications are running .!

Can you tell us how to do that? Thanks.

I'm now keeping a log of which WUs affect performance and which don't.

In five days:

1. I've had no performance problems with three NOELIAs and one NATHAN
3. One NATHAN gave performance problems
3. Three NOELIAs and one NATHAN stopped with errors
4. Today I aborted four NATHANs for serious performance hits.

Nothing conclusive yet, but it's beginning to look like I need a way to not to get NATHANs...

Jlhal, it could be a driver problem, I have working for several days with a problem of stopping WU's and unresponsive system.
I just downgraded to driver 301.42 and it is working now as I was used it did.

Hi TJ !
Well, I want to try some day to play again while GPU is crunching and with/out multigpu enabled on my GTX 690
My problem with SLI were with a GTX 590.
All WUs (except for 1 frozen NOELIA I had to cancel after 43h) are running fine on both GPUs at the moment with the latest drivers for Windows 7 and Ubuntu.

Lubuntu 16.04.1 LTS x64

I'm now keeping a log of which WUs affect performance and which don't.

Today I aborted eight Natans, one after the other, 'cause each just about froze my PC. I set Gpugrid to 'no new tasks' and will try again tomorrow.

I found the solution. I did not know that, after unchecking "Use GPU while computer is in use" in BOINC / Tools / Computing Preferences / Processor Usage, I had to activate this preference in BOINC / Activity by checking "Use GPU based on preferences".

Now when I wiggle the mouse in BOINC / Tasks, the GPUGRID WU immediately gives "Waiting to run". Perfect!

I had similar problems, with freezing screens or WU'that error out after 15-20 hours running.

First thing I did was downgrading my nVidia driver for the GTX285.
That helped a few weeks, then it happened again.
I found out that Windows was trying to update some software for the graphics card.
I have disabled that and now it runs fine. Same option as you, GPU based on preferences. But my preference is "Run always". And it does without problems so far.
