I was about to say there are 128 core machines, but you actually meant 96 cores not threads, so 192 threads!  Sulk.  I have 24 threads (on each of 4 machines).  I just call threads cores, since they behave like them and if you don't use HT you miss out on a third of the speed.

[Looks up Epyc 9654]

4 times faster than my Ryzen 9, but 8 times as many cores.  So half speed cores.  Good for Boinc, but not good for interacting with or playing games, or running Boinc tasks which need done quickly (as I've not heard of a Boinc task taking more than 16 cores).  

$3000 is a bit much for a CPU though. 

Try yafu myfirewall.org/yafu/ you need the number of cores available to run the selected apps:

Run only the selected applications YAFU: no
YAFU for small composites: yes
YAFU-4t: no
YAFU-8t: no
YAFU-16t: no
YAFU-32t: no
YAFU-64t: no
YAFU-128t: no

If it's an ARM processor, how do x64 programs (eg Boinc projects) run on it?  Will it only run projects designed for Android phones / Raspberry PIs?

I always thought that was DUCK tape.  It's certainly easier to pronounce.

Jesus, the image insertion in this forum is tedious.  I can paste from a web page, but not from a photo editor.  I can't resize the image without manually inserting the pixel size, there's no drag handles.

If this page takes an hour to load, reduce posts per page to 20 in your settings, then the tinpot 486 Einstein uses can handle it.

Can someone explain inserting

I'll try Yafu again, looks like I had difficulty setting up an account last time, because my normal email address is not accepted, but my browser wanted to fill in a different one.  However it won't accept my usual Boinc password.  I tried to send forgotten password, but I got no email.  I've added them to the whitelist on my ISP's spam filter, but that takes 30 minutes WTF?

That says "or 8" at the top.  Now show me an 8 :)

And do the CPUs have to be special?  Is a CPU just "multi-CPU" compatible?  Or is a CPU capable of 4 different to a CPU capable of 2?

Peter, My understanding is

Peter,

My understanding is limited. But I do know there are specific data channels that are used to coordinate between the CPU's. If I am not confused those data channels subtract from the rest of the available bandwidth that would otherwise be present on each CPU chip.

Back when 25 cores was considered to be a server class CPU this was the only way to get 100-256 cores on one motherboard.

These CPUs were not all that fast either. 2 GHz maybe.

Before GPU's got repurposed as calculation accelerators this was one of the ways you could increase system production.

I vaguely remember these monsters running in the early boinc world. I don't remember if they were prominent at seti@home.

Now besides the boinc model and however they lash HPC together there are distributed computing models like Beowulf that present a single system to the public but are in fact networked systems that has a controller/distribution node sending work to subsidiary systems.

I don't know much beyond this.

I've failed to find an 8 CPU

I've failed to find an 8 CPU board.  Everyone says it's not possible.  It would have to be larger than any case including servers could fit.

While searching for

While searching for motherboards, I found someone trying to sell one after photographing it on his LAWN!

But it's ok, he uses an anti-static bag:

A quick search found a MB with 4 cpu sockets on it:

And some 8 cpu socket MB's as well:
