What path do you walk to be able to figure out this kind of black magic by yourself?

It's just like the end of Portal 1: you have to remove some cores in order to win the game. ;)

For anyone curious/hopeful, this only really disables the cores in terms of the kernel.

They're still consuming about the same power they would normally (when idle) :)

Edit: cpusets would probably handle this better dynamically. I'm not sure if that influences the count visible to a process

This isn't really black magic.

Just reading a book on the Linux kernel and it's structure should be enough to get you going.
