If you run ‘top -M‘, CPU states are reported on a per-CPU basis. It turns out that having over 110 CPUs will cause a segmentation fault – but not any longer! I wish I had a screenshot for this.

Justin. News article FYI.

Microsoft adds Unix sockets to Windows
Phenomenal. With EPYC, 128 threads (virtual cores) are now within reach…for a price of course. We can now really begin to see how DragonFly scales.
Has anyone tried DragonFly on Ryzen Threadripper? What a beast of a CPU.
+1 for Francois to update the 3 year old benchmarks.
You can rent (cheaply) an Epyc server too

Wow, you can rent a fully maxed out (dedicated) Epyc server for about $500/month.
That’s fantastic!
Would be great to see these old benchmarks updated

Nikki,
Have you donated that amount to the project so they can use it to rent the Epyc server?
Can you donate money specifically for said cause?
If so, I’ll definitely donate $500.
But if there is no garuntee my donation will be used for that cause – then no, I’m reluctant to donate.
Yeah, I’d make sure there’s someone with time/interest in renting an Epyc server, first. Ask on IRC and see.
