Project 18409/a8 EXTREMELY large WU???

Post by FaaR »

I've never seen anything like this before - ever. ETA is 19 hours 49 minutes right now, and it's not even 50% done. Folding on a Core i9 7900X on 17 threads, clocked at 4GHz.

Super weird. I can't say I really desire to be assigned such mammooth work units, because I am not a habitual folder, so feeling a need to keep my machine turned on 24 hours a day to finish any more of these does not appeal to me.

They're big but not the biggest. There are bigger.

They've been running for a few months now.
You do have a full week before it times out, if you need it.
My Ryzen runs those in about 37 hours.
The bigger work units take my Ryzen a little longer, at 41-42 hours.

I am running a P18420 on all 16 virtual cores of a Ryzen 3700X and it is taking 44 hours.
And a P18411 on all 16 virtual cores of a Ryzen 5700G (great chip for Folding by the way) is taking 37 hours.
Both are on Ubuntu 20.04.3.

I don't think more cores will do you much good. These work units can only use so many.
And FAH does not use much cache. And you would have to pay a lot for faster speeds. But it is your money.

Anecdotally, I find that there is a point of diminishing returns when adding more cores to a job starting after about 50% of the total cores of the machine.

Project 18409 has a Timeout of 7 Days. So if you only work on it 12 hours a day.. you'll still get it in on time.

Also, I remember being told you should Not set the number of CPU Folding cores/threads to prime numbers. That it created stability issues. If nothing else, you should drop your core count from 17 (a prime) to 16.
