Hello, I was wondering if there is currently a Linux Distribution with multiple CPU support (not multiple core support) or if I would have to make my own. Thanks for the help in advance.

More about : linux distributions support multiple cpus

If im not mistaken all Linux kernals contain Completely fair Scheduler (CFS), this works well with multiple processors with multiple cores.

I know supercomputers run highly-customized Unix, but I wasn't sure if there was one I could download instead of writing it myself.

Multiple core/cpu support has been in the kernel for a great many years now. I don't have the reference handy at the moment but if memory serves the default kernel options are set for 8 cpus and 32 cores. For more than that you have to compile a custom kernel.

Yup, the feature has been. You should be fine as long as you go with a Linux Kernal version greater than 2.6.

Cheers.

I was running ordinary distributions of Linux and FreeBSD on dual-processor servers more than 10 years ago. The OS doesn't care whether the cores are on one die or two; it works just the same.

Linux has had support for multiple cpu (and multi core) since version 2.0 in 1996. it is called SMP.

Ubuntu default:
32bit: 8cpu/cores
64bit: 256cpu/cores

All Linux distrobutions will come out of the box with SMP enabled unless you have specifically compiled the kernel with option
  1. CONFIG_SMP=n
