Over 27,000 WUs queued and ready for BOINCers to DL. Looks like you upgraded the server and you're more than ready for the next Race Day.

That's why I'm confidant that switching the server to supply only 2 WUs per CPU thread would work great and mean that one could only bunker about 8 hours of work instead of several days worth.

Theoretically. If you really want to maximize your cache of workunits you could also lie about the number of cores (say that you just have 8 but you can easily tell the server that you have 128) or (although not so easy to implement) you may also start a lot of different clients on the same pc. So, at the end, if you really want, you may bypass any server side limitations.
On the other hand, forcing a small user's cache will create problems to users with intermittent network activity.

I heard that some at SETI did that. They made a custom BOINC client or something like that. Claimed it helped them make it through workless Tuesdays.

I switched back to Resource Zero.

I didn't say that there was no bunkering going on.
I said that the reason for work scarcity is that work requests are more frequent than WU generation.
Yes we all know that TN-GRID could put a faster server to good use.

BTW, tasks in progress normally at TN-Grid:
25...35 k during this month, 25...55 k during the past several months,
right before the start of the current challenge: < 80 k,
right now: 53 k
These less than 80 k in progress do not look like a massive bunkering effort to me.

Bunkering would contribute to work scarcity if the bunker builders would issue frequent work requests over a prolonged time, and it would cause work scarcity if the number of tasks in progress would inflate the database so much that the work generator stopped producing.
I don't bunker but here's what I think happens. First, increase your queue to request as many WUs as you can get. Then run them but don't return them until after the race starts.
With a slow work generator this makes it likely that all WUs will be depleted.
Since this project has quorum 2 this works in my favor. Since I return all my WUs immediately my bunkering wingmen hold the 2nd Q WU until after the race starts and so push my recent credit into race points.
The Science Status page showed the rate dropped from 55/day to 44/day yesterday and now it's back up to 51/day. Since it's a 10-day average the dip was actually bigger. I'd enjoy seeing a long term graph of the work rate.
Before the race I was running TN-GRID as my only CPU project with Resource = 0. It runs really good that way or as a backup project. That's why I'm confidant that switching the server to supply only 2 WUs per CPU thread would work great and mean that one could only bunker about 8 hours of work instead of several days worth.
The good news is that the work is getting done.

Will there be some WUs ready to be send tomorrow?

Just Say No to Bunkering.
They should use the 2 WUs per CPU thread mode and we wouldn't run out.

...Diamond is the top right now, should find something more valuable

I thought ruby was more expensive but blue & pink diamond and jadeite have it beat.

You should add Platinum at 250,000,000 and Rhodium at 500,000,000.

And I get a better Application Name: gene_pcim (fma)
It only makes sense that all i9s should work best using the same instruction set. Now to sort out the i7s and Xeon E5s.
From what I've seen on i9 new builds that start with a fresh slate and run the test over all 3 instruction sets I'm seeing 7% improvement of fma over avx and 4% for fma over sse2.

Placing this app_info.xml file in my project folder switched from avx to fma:
<app_info> <app> <name>gene_pcim</name> </app> <file_info> <name>gene_pcim_v1.10_linux64__fma</name> <executable/> </file_info> <app_version> <app_name>gene_pcim</app_name> <version_num>110</version_num> <avg_ncpus>1.000000</avg_ncpus> <flops>6420118510.968211</flops> <plan_class>fma</plan_class> <api_version>7.9.0</api_version> <file_ref> <file_name>gene_pcim_v1.10_linux64__fma</file_name> <main_program/> </file_ref> </app_version> </app_info>

Has a different Application Name displayed in BoincTasks but it seems to be working good so far.

Is there any way to trigger the Instruction Set retest???

I ran CPU Benchmarks. Two computers changed a lot and that triggered it.
Several computers are obviously running a slower IS. Wish I had a Trigger button to push.
Tried Resetting the project and also detaching and attaching. Neither work. Still have computers stuck on the slow IS.
I guess I have to learn how to configure an app_info file to force the correct IS.

Other important factors while comparing computers, for our application, are the RAM speed and CPU cache size.

I'd like to learn about this.

As mentioned earlier upgrading a CPU or Merging will confound that computer's performance history.
