Oh my, that's a big one

Postby aetch » Wed Aug 11, 2021 5:47 am

P16983 base 55,000. I don't think I've had such a big cpu project before.
My client is estimating a time of just under 12 hours.
Ryzen 9 3900X, 16GB, RTX 2070 Super, Win 10 Pro, F@H 7.6.21

Let those WU's hit that 30 core CPU slot on my 3950x system.... I'll appreciate those points.

It's currently running on 21 of my 24 (the rest are given over to the gpu and OS).
It's estimating my PPD at 285K, which is about typical for my cpu.
It just means it's one big project instead of lots of little projects for roughly the same points.

I just hope Voelz was able to set a lower limit on the cpu this monster is sent to.

More likely to be a higher limit set for the number of CPU threads. With 23,400 atoms in the WU, beyond a point using more threads does not increase the processing speed. If this project was using Core_A7 instead of Core_A8 that is being used, domain decomposition errors could also be an issue.

I don't see any entries for this project on my systems, but would guess these WUs have a large number of steps to get the number of points involved instead of being large in terms of atom count.

10 Million steps.

A quick scan of my logs shows previous work units up to 2.5 million steps.

Anyway, 4 hours in, no hiccups. It's on target for a sub 12 hour run. *fingers crossed* I haven't just jinxed it.
