Hey Everyone,

Sorry, I put up a bad set of runs on Friday. They're down now and I'm going to check out the errors now.

Sorry again,

Jake

Sorry, I still get bad wu's.

Some of these wu's fail on other systems too.

I tried this on my GTX-750ti in Ubuntu 14.04 and get the following. I am running 334.21 which as far as I know is the only driver for this card in Ubuntu at this time. The card runs Einstein, DiRT and Collatz fine. But it does not run Folding@Home currently. Is this just a matter of waiting for the developers to provide work units that support Maxwell, or is there something I need to do?

I can run MW on my GTX 750ti, using win7.
Your message looks like you have no open-CL package installed. I would start there when looking for a solution.

Absolutely no problem, look at this pc:
http://milkyway.cs.rpi.edu/milkyway/show_host_detail.php?hostid=581360
It's not a problem to mix cards and it's not a problem to mix apps.
I can run GPUGRID and MW at the same time on the nVidea card, Einstein and MW on AMD and Einstein on Intel.

Hi,
How do you configure 2 project at the same time on one GPU card ? My PC like yours, one AMD and one Nvidia so I want to try it. I run Milkyway Einstein GpuGrid and Seti. It is a good way to eliminate free cores and unused processes at the GPUs.


That's easy. With an app_config.xml you can set the cpu and gpu usage. I've set Einstein and Gpugrid to 0.34 gpu's, which means, it can run two wu's. And I've set MW to use 0.25 gpu's, so the BM loads another app to fill the gpu usage to the best value near 100%. The actual mix of apps ist then controlled by the ressource share settings.
When no MW wu's are available, it will load Einstein for AMD and Gpugrid for nVidia, since ressource share is set to 0. If you use the same share for all projects, the mix changes from time to time. With the app_config as described you have always at least one MW wu per gpu running.

Edit: sorry its not app_info, its app_config.xml

What I find an absolute nightmare is trying to get AMD drivers to load when I also have NVidia GPU running:-( Dunno what the secret is but its eluded me..


I didn't think that was possible, I'd never try mixing the cards. In fact I've even had problems when replacing a Nvidia with an AMD, if you don't remove the Nvidia driver first, it goes mental when it sees an AMD card and gives a blue screen. And since the Nvidea card was dead, that proved very difficult. I only use AMD (the above was a friend's machine I was trying to repair) since Nvidia like to overheat, they're less powerful for the money, and I don't much like their drivers!

I'm not really sure how practical it is to use these mobile devices anyway. Other than not being very powerful compared to full higher end PCs, they're specifically made and optimized to be mostly idle most of the time and aren't suited to being up and crunching in the background for extended periods of time.

In practical terms, I think supporting them is more of a novelty to generate interests in these scientific projects, which of course is a good thing as well, but not an efficient use of project resources. There are much more powerful and available platforms which are left ideal too often as it is now anyway. These mobile devises deserve to be on the bottom of a priorities list, if not left off altogether, until such time as it becomes more practical to use them.

This isn't meant to offend anyway. I myself very much enjoy using, customizing, and playing around with some of these devices. I think it's important to acknowledged their limitations and more fitting usage scenarios though.


No.
14 months ago I added an Odroid to the project, an overclocked to 4x2 GHz Arm V7, crunching 24/7 MW only.
It took less than 5 weeks to see this device in the top 10,000 by overall credit!
I have my very first tablet in the kitchen as a radio, it did also crunch MW until the app did no longer work, also 24/7.
I have a 8" tablet, that was fallen down; 40% of the touch area is no longer working as a touch, but it works 24/7 as a crunching device, currently only for the skynet pogs. It has an average credit of 1,405 an an overall of 467,900.
Much better than throwing it away!
I love android wu's!

Great work, Jake,
works fine on three pc's now.

There is always Linux!!

I tried it twice.
Was unable (also with help from a forum) to install AMD openCL. It worked easy with nVidia.
I followed a three month discussion @ Einstein. I never had a crunching AMD Linux version.
No, thanks.

Well, yes, they start crunching, but at ~70% they restart with 0%. In 45 minutes not a single gpu wu finished.

The problems have shifted a little bit.
At the moment the work generation is the bottleneck.

Unfortunately they do not work anymore. The project was updated some months ago and the old arm wu's all fail.
Believe me, i am sad too.

Hi Sebastian*

I have some think similar like your problem when I run cosmology what ever project used GPU WUs hang. I cant find what cause this so I leave to run cosmology. My pc have win10 and install latest drivers (1 amd 270x and 1 NVidia 750TI).


Yes, I know this problem. I have this on my PC with the HD58xx card, when running Einstein and MW mixed. Sometimes a message like 'AMD driver reset after driver error' is displayed. Other systems accept these settings, but with older drivers.
The 'HD58xx-System' is a 'repaired win7' after many crashes and an abstruse mix of programs and browser add on, cleaned but never prooved to be as 'out of factory'. This is why I never payed too much attention on it. But works with 4 MW simultanously.
Check my systems for driver versions, currently all my systems work fine with MW.

Thank you,
a clear answer!
Good luck for your work!

Are these problems solved?
If yes I will rebuild one PC to run 2 of these gpu's.

Posted 2 Nov 2016 by Profile Werkstatt
I'm crunching gpu wu's only.
I've set my computers to store wu's for 5 days and an additional buffer also of 5 days.
Hours later I had wu's for about one hour.
I want a buffer for 4 to 5 hours to keep my gpu's active during the many short database outages.
Any ideas beside crunching other projects?

OK, thanks! So it looks like that's not an issue anymore.

Are you running Catalyst 15.7.1 by chance?


No, it's 15.09
