Not a big deal for me, since I already have scripts to distribute the workloads I use across multiple machines. Anyway, it would be hard to use 128 cores concurrently for one process in an efficient manner (given memory contention, NUMA issues and other factors).

I use 62 cores on my 64 core box all the time. It is my default setting.
Now, to be
efficient with lots of cores, the program must be NUMA aware.
But, for instance, I am quite sure that the TCEC contest is on a NUMA machine.
Arasan seemed to run pretty well on it.

Interested yes, but I am afraid my lovely wife would divorce me.

What you need to do is make a list. Wife: pros and cons, blade server: pros and cons. If the wife wins, make sure you burn or eat the list before she finds it.

Cluster in a box

Curious are there 4 PSU as well or does it have some nifty one that powers 2 or more?

Slick man! Part of me wants to see a crafty benchmark on a 32cpu node

I did the same thing with my 64 core box.
