1) Message boards : Problems and Help : Einstein@home and PrimeGrid together on the same machine? (Message 110954)
Posted 988 days ago by puh32
Thanks. Good to know that I'm not doing something wrong, at least.

It would seem like a BOINC issue they should attend to at some point.

On a related note, I'd like to play around with the "Resource share" column (tab) in the BOINC "Advanced view" to see how the projects/BOINC behave when I change their resource share. (At least I'm under the impression that this can be done?) However, I seem to be unable to do it. How is it done?

I was hoping you could help me with the following problem.

Windows 10 box, 2 Nvidia 1070.

I use my two GPUs for Einstein@home.

I would like to use my CPU cores (ideally 4 out of 8 hyperthreads) for PrimeGrid.

Turns out Einstein@home uses one GPU and one CPU hyperthread per graphics card. Thus, 2 CPU hyperthreads remain for PrimeGrid.

However, BOINC fails to see this, and thinks that 4 CPU hyperthreads are available to PrimeGrid. Well, they are not, and BOINC ends up having to crunch the two first CPU tasks, keeping the other two CPU tasks on ice until the two first tasks are completed.

And when the two first tasks are completed, it switches over to the two tasks on ice *AND* requests two new CPU tasks – just to put them on ice immediately.

Obviously, having PrimeGrid tasks on ice for a couple of days is not ideal.

Is there a way around this? (Am I doing something wrong, or am I interpreting things incorrectly?)

Trying to reinstall the driver a couple of times, and after a couple of reboots, did not help.

But removing all Nvidia stuff manually, and then doing a clean driver reinstall seems to have done the trick.

Guess I should have anticipated that, in hindsight.

Say what? All I'm getting is:

"NVIDIA installation cannot proceed.

This driver is not compatible with your version of Windows."

v382.05, 980Ti

I also did the new Win 10 Creator's Upgrade (by accident).

Found out that the Nvidia drivers (even the latest one, downloaded today (980Ti)) are not compatible with the Creator's Upgrade.

So I guess I just wait for a couple of days, until a new driver becomes available? Or how have you dealt with it?

(Sorry that I caused nearly 500 "Error" work units. Happened when I slept.)
6) Message boards : Generalized Fermat Prime Search : GFN21 GFN22 Scoreboard, post your times/hardware (Message 106526)
Posted 1194 days ago by puh32
Recently ran my first GFN21 and 22 tasks on my GTX 980 Ti:

GFN22 - Run time (sec): 187,099.15 - CPU time (sec): 658.23 - Genefer 22 v3.13 (OCLcudaGFNWR)

GFN21 - 95,441.37 - 289.42 - Genefer 21 v3.13 (OCLcudaGFN)
GFN21 - 96,064.81 - 293.05 - Genefer 21 v3.13 (OCLcudaGFN)

Nothing else than BOINC was running on the computer.

( Don't forget March 30, the Bunsen Burner Day.

Or March 20, the World Sparrow Day.

Plenty to choose from.

There is even a "Alien Abduction Day" these days (March 20, like the sparrows). Not sure how that one is celebrated though. )
8) Message boards : Problems and Help : Windows 10 reboots after upgrades (Message 105420)
Posted 1227 days ago by puh32
I suppose I'm not the only one who is frustrated by the way Windows 10 reboots after upgrades, "when nobody is using the computer".

Problem is, I use the computer. I just don't move the mouse.

Very frustrating to realize that you have "lost" a couple of days of computation just because Win10 decided to reboot at some point right before the weekend.

I read that there is nothing you can do about this except make changes in the registry / turn off updates altogether. Can that really be true?

I speculate:

You have both a virus protection program and a malware protection program running in the background (Windows). That's at least what I have.

You have neither of those on your Linux machine. At least I don't.

>Looks to me like they're separate. They just have very similar id's: 514770 and 514470.

Ouch... stupid of me! (I did, in fact, misunderstand something :)
