I have 832 threads running, mostly optimized for cache and affinity.

Sounds like most on the TeAm are deep in the optimization business now. :-)

I wonder how long a single thread takes on one of these tasks?

Certainly depends on what the other virtual machines on the same cloud computer are doing. Would be rather traumatic for a machine if it had 96 single-vCPU VMs all going for PrimeGrid work at the same time. That'd be a rather unlikely scenario though, unless the provider tends to concentrate a customer's VMs on same nodes. (Not sure if any provider is doing that.)

Edit:
tng's take 51 hours for llrCUL:

After a long while I am lurking in the SETI.Germany forum a bit again, and found pschoefer's report on the cleanup stage of several past challenges:
Our TeAm had 4 invalidations in the cleanup of the WW challenge of September, 2 invalidations of the PPS-LLR challenge of July, and 1 invalidation of the GFN-17 challenge of January. Most of the other teams didn't have any invalidations, but then again, we were the team with the most results in each of these challenges.

These units (CUL more so than WOO) are really showing the 16mb cache on my 5700g is very lacking versus the 3700x 32mb.
3700x is running 7.5%/hour on woo vs 5700g getting 4.5%/hour

Probably a @TennesseeTony task unstuck from the mud from a year or two ago? Anyway if it finishes it will be a great year! To have "the Foot" as in BigFoot tony back!!!!

Maybe just a sighting though? ;)

Do these work here. This was the most demeaning? I tried.

Reading up on some other stuff, the server troubles during the short PPS-LLR challenge came to my mind:
In July Skillz said:
We have almost killed the PG server in this challenge.

View attachment 64998

They're going to let it run it course, but once the server reaches a point that it can't accept anymore uploads the challenge will end. Which they think might happen early, but they're hopeful it'll make it to the end.

I am shutting down most of my rigs in hopes we don't kill the server. There is no chance anyone will catch us as a team, even if everyone on the team stopped crunching 100%.

With that said, I've set NNT on a lot of my rigs and shutting them down when they complete what they have.

Back then I didn't entirely understand what the precise bottleneck was, and if/how participants could help to avert it.
Now I found this older explanation of the server-side workload for LLR2-style "main task--proof task" verification, and it becomes clear:
PG thread "LLR2 installed on all big LLR projects", message 143359, message 143362, furthermore message 143777, message 145281.

Well, thanks to the clouds, I am now 3rd. But I think I have that locked up.

Edit: nope, looks like xi5ku will pass me. More cloud ?

Stats in this challenge will jump around a bit, given that one or another team is also bringing single-threaded cloud VMs again.

Yeah, this morning I felt like I'd been hit over the head with a waffle iron, but now I don't. :p I imagine I may again soon, though.

xii5ku doesn't run cloud. Those are all his systems, optimized 150%, greased up daily to get the most that those systems can possibly produce doing the work.

As you can see my line is pretty straight. I had a 2 hour outage yesterday while the electrician fixed outlets that had melted wires.

So, I am going to stop updating "I made 2nd" then "I went down to 3rd", this has happened like 4 times today. Currently 2nd though.

xii5ku is trying for sure, but I don't think he's got a chance as long as you take care. :-)

Stefan,

Where or How or did you find or make this chart? You pulling data from the project and creating in your own "Stefan" data tracker? I see that Highcharts.com is used, so you must be doing your own data pulls and stats?

Is it from a site somewhere that is already crunching and tracking these stats?

I only know of this "extra" stats site....
