Are there any Linux Distributions that support multiple CPUs

[Jfdude]

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.

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.

Thank you all!

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

CONFIG_SMP=n
