CPU Support
 

I've googled until my eyeballs have almost popped out, yet I cannot find anywhere that tells me for definite that any of the Fedora distributions support higher than dual-processor (single-core) or dual-core processors out of the box. Can anyone enlighten me if quad-core+ is supported?

Red Hat Enterprise Desktop: 1 socket
Red Hat Enterprise with Workstation: 2 sockets
Red Hat Enterprise Linux: 2 sockets
Red Hat Enterprise Advanced Plattform: unlimited sockets

Each socket may be equipped with multiple core CPUs. However the limitations for special architectures apply.

For example HP 9000 Superdome servers may have 64 CPUs with 2 cores each.

Fedora should support 2 sockets with unlimited cores each.

Isn't it that you can easily recompile kernel for more processors (replacing only kernel itself)? Also looks like these limitations are just support limitations, not technical - i.e. it will work, but you have no right for technical support.

O.K. The terminology that you are searching for when it comes to multiprocessor systems is SMP. It used to be that you had to install a different kernel (SMP kernel) if you wanted multiprocessor support; but as of Fedora 6 there is one kernel for both uniprocessor and multiprocessor systems. The standard kernel 2.6.X supports up to 64 processors so you can throw pretty much any processor combination at it. Now, for instance, if you set up a system that has two single core processors, as long as your motherboard is supported by the kernel, then the kernel would view both processors and adjust itself accordingly to support those processors. Multi-core processors are read by your motherboard's bios and then displayed to the kernel as if they are separate processors for each core. So, a quad core processor would be displayed to the kernel as 4 processors. So, yes, as long as your motherboard is supported by the linux kernel then yes you could use a quad core processor, a dual core processor, or two seperate single core processors. Now with multiple multi-core processors on the same board, it's not a matter of the kernel supporting it, its a matter of hardware compatibility. (that may require "server" processors? But I haven't looked into that too much.) Hope that helps.

Thanks for the info, guys. That's just the info I was looking for!
