4090 unchanged. 3080TI slower. Titan V VERY slow. The older they get the more they increased. 3090TI and 4090 are about the same.
It’s different on the 4090 too. You are just still crunching older tasks. Old tasks are about 1600s new tasks about 2400 sec on 4090

And a quick look at your 4090 tasks clearly shows some of them running in the 2400s range, so yes you are seeing the slowdown too.

Run times on my 3060Ti and Quadro RTX 4000 have increased by about 40% for GFN-20 tasks, with virtually no change in the credits given for the tasks.

PPD for the 3060ti dropped from about 500K to about 320K with the new tasks. :(
And the RTX 4000 dropped from about 330K to about 240K...

Well, it was nice to have first place on the team for one day. I doubt that I will have it tomorrow.

That's going to be a bit difficult for me for two reasons: After I gained some weight yesterday and more today, those six are rather phat now and require a fisheye lens to watch. And I am distracted by secretly plotting to overtake a couple of guys in front of me.
ALL my balls are in the "air" so to speak on this one.... We shall see if they land happily :)? How do you speel Haappilly ?

Had a long power outage last night,
I had a brief power outage a few weeks ago. This kind of outages happens at a frequency of once or twice a year here; I haven't kept count. Somewhere in the city grid, a fault happens, and in order to locate the fault, the power company toggles some switches of theirs, causing brief blackouts elsewhere.

Yesterday evening, a substation was down for half an hour due to an as yet undisclosed reason, causing a blackout in several city districts. Luckily mine wasn't affected. This same substation was out for >1h earlier this year, possibly due to some sort of vandalism. An unauthorized person was found on the premise and subsequently locked up in psychiatry.

Seemingly, power outages didn't happen as often in the town where I lived until a few years ago. I don't know what's up with this place.

At least blackouts due to severe weather are extremely rare in Germany. The last one of those which I experienced myself was in my childhood during an extraordinarily severe winter.

In our power grid, there are things like automatically reclosing circuit breakers, so if some momentary fault occurs, the power comes back on very quickly, which still necessitates mass reboots. But the infrastructure here seems a bit vulnerable to accidents, like trees falling or vehicles hitting poles, which happens more than I like, several times a year at least.

I think someone ran into a box on the side of the street, just down the block from me. That kind of thing seems to happen a few times a year. Street racing, probably. :rolleyes: I'd much rather race computers. ;)

500m in both PPS Sieve (Pending validated) and GFN apps during this competition. I'd probably be a few places higher but Rosetta has actually had a decent amount of work so my CPUs have been there..

The most stable power I've had was at my last place in NOVA where power lines were underground.

21 TeAm-mates! That's a lot! :)

Probably time to check on your GFN-20 tasks. You might need to switch to something shorter.

My GFN-20 tasks are taking 7:15. My GFN-19 are taking 3 hours, on slower hardware. I don't see a need to do anything until the morning. (14 hours away for me)

Thats not counting the GPU tasks that are taking 24-33 minutes for me. OOPs I have one taking 40 minutes..... some over an hour for slower than 4090.

Great job by everyone. We swept the Primegrid Challenge series this year making this our third year in a row for winning first place. Although we tied for first place with the Antarctic Crunchers the first year (2021) and won it undisputed in 2022 and 2023.

Not to mention the two Pentathlon wins in 2022 and 2023. We're getting pretty good at this stuff. :)
