Why don't you click on Donate and send them enough money that they can hire another person to create workunits?

I decided to catch your suggest on the fly.
Always claiming for new WUs/features, I also think that it may be fair to collaborate with some counterpart, beyond our computing power.
But unfortunately, it seems that Donation form is currently unavailable...

Wait and see !!!
Toni, so many times announcing WU and never something.

And when there are, the first take all WU, crunch it of course, but nothing for the other.

It will say the first takes all, and so can falsify the world competition.
I suggest to limit the WU by user, not by host.
A user with hundred GPU, receive hundred of of WU, user with one or two GPU, receive ... nothing !!!

And world competitions is so falsified (like SETIBZH )

It is more or less the same on Xanson, latest year !
The user who knows when WU will be released have a serious advantage, can take a lot of and nothing for other.

So I suggest ti set limitations also on user. Limitations on 2WU/GPU is not enough.

I enjoy competing as much as anyone but competition and stats are the last thing projects should be worried about. They should focus on doing good and useful science first, and issue work according to their needs in whatever manner best meets their goals. There is zero reason to limit work here as you describe, unless the project sees a need for it. Some getting more work than others and some sort of potential stat distortion isn't compelling enough to make such drastic changes.

Let's remember that we serve the project, not the other way around. If they're getting work done in a timely manner and getting the results they want, that's really what counts.

This is not a competition. This is cooperation.

👍👍 May I also add that being here volunteering time on a GPU that takes more than 80 hours to complete and upload a WU is actually delaying the project, IMHO.
Do you agree, Retvari? I was finished with all mine a week ago.

Sorry, but this is silly. When there is work, a user with 100 GPUs gets at most 100 WUs, whereas a user with 1 GPU gets at most 2 WUs. When no work is available, none of them get any work. How is this not fair? You are not seriously suggesting that the scientists limit their progress rate so that users with fewer GPUs can have bigger numbers on BOINCstats etc.?

I create WUs when they are actually useful. It may not be appropriate for a competition setting.

Competition can not be the correct motivation in my opinion: it would not provide an advantage to science, while leading to "busy work", credit inflation, cheating and all sort of nasties.

@Toni - you must absolutely do what you consider best for the project at all times.

However, I do also think that the challenges such as Formula Boinc, BoincStats etc are truly excellent in that they provide other reasons for people to become / remain interested. Challenges provide a willing and motivated source of crunchers so that is quite clearly an advantage to science.

The only 'nasties' I am aware of are basically people who THINK that there is cheating taking place - or that it is even possible

Message 53711 - Posted: 21 Feb 2020, 8:09:15 UTC - in response to Message 53641.  

The powersupply is a Corsair CX750M.

I have the same power supply Corsair CX750M. And I have the same problem you describe:
Suddenly this month it seems like something is making my system overheat if I enable the GPU tasks.

Have a Ryzen 9 3900X that I've been running full tilt for like 6 months now, no problems.

Then suddenly system hangs, with all the fans (CPU, GPU, Chassis, etc) all off and the motherboard unresponsive to the reset buttons and the power button. The LED's on the Chipset and Motherboard remain lit.

To resolve I have to turn power off at the PSU, and then boot.).

My system is AMD 1700x and a GTX1070. I tried to resolve the problem by lowering clocks on the CPU since the beginning. What seems to help, is lowering the frequency of the GPU by 120 MHz and increase the fan speed to 97% on this particular GPU. But still the computer freezes frequently.
Lately I was wondering if it might be the PSU as well, as I had a "bluescreen" problem on another computer, I solved with a certified, higher Watt PSU a few years ago.
So it seems to me, that this might be a bad PSU design for 24/7 crunching.

I have Asus B85M-E mobo with i5-4690K 4 core cpu and RTX 2080 super gpu. This system has Corsair HX1000i psu. Steady running GPUGRID with Win10, gpu load rate 96-97 percent. Psu fan hardly ever rotates, usually only during power-on stage.

Watching to the header of this thread: “Large scale experiment: MDAD”
Large scale suits perfectly the current situation: 211,715 WUs ready to send... And growing.

Where can I find information on the relative performances of GTX 10 series graphics boards to the newer GTX 16 and RTX 20 series boards for MDAD workunits?

I'm not interested in their relative performance for games.

The purpose of the work is (broadly speaking) methods development, i.e. build a dataset to improve the foundation of future MD-based research (not just GPUGRID). More details may come if it works ;)

Still waiting with bated breath for more details...
