I opened a new account, since their system refuses to send me an email to correct my lost password.

Looks like nobody's doing the big ones.  Zero 128t and 64t in progress, and only one 32t.  I've only got 24 threads per machine, so I can't help with the big ones.

I have a pc with 32 cpu cores and they still take awhile to finish but I can't do the 64t or 128t tasks like Tom can.

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

And some 8 cpu socket MB's as well:

You mean like https://www.supermicro.com/en/products/system/mp/6u/sys-681e-tr ?

That's two 4-CPU boards in one case.  I wonder what the OS sees it as?  Or is it just two computers in one box and you install two OSs?

Are the 64 and 128 tasks different, or are they just a more efficient program doing the same work?  If they're actually different, they're not getting very much work done at that level.  Yafu isn't on the Boinc list, there's hardly anyone there.  I'll run my CPUs on it for a while and see what position I can get to!

when you get to this many CPUs most vendors put the CPUs on daughterboards to stack things more vertically to save space, might also be necessary for trace lengths and such for the UPIs between the furthest CPUs. it's still a single unified system and it will see all 8 sockets under a single OS.

A 3D computer, like the high bandwidth memory I've seen on some GPUs.

I wonder if they'll ever make 3D CPUs?  Heat could be a problem, but if the CPU was a cube you could get tonnes of cores in there, all right next to each other.

Don't all water coolers

Don't all water coolers achieve those sort of temperatures?

And it's not a good idea to take the lid off, it makes it much more fragile.

The 64 tasks require a 64core cpu while the 128 tasks require a 128 core cpu, yes you can get thru HT but if you only have a 16core cpu, even thru HT you can't get any of the 32, 64 or 128 tasks.

Yafu doesn't want a billion people running it as they are still growing and don't have the hardware to support alot of new users so they have asked to NOT be on the list. A few other projects are the same way and when they do get alot of new users their hardware often fails because of it.

No, if you view the original YT video announcement of the product, the baseline was set with a 280mm AIO and runs at 90℃.

Then the cpu is delidded and the new fabricated lid is installed on top of the dies.  The new IHS is much more robust than the stock one and protects the dies. 

Then the AIO and custom block solutions are installed on the cpu using the standard mechanisms and the temps are significantly better with each progressive solution.
