Maximum Number of cpus with SMP


I would like to know which version of kernel supports the maximum number of cpus (SMP) and what is that maximum.

Thank you

I think the latest can handle up to 64, I might be wrong, could be more, haven't checked in a while since I don't have any machine that has more than two..

Re: CPU's

If you are running a SMP kernel then check your /proc/config.gz file.

# grep NR_CPUS /proc/config.gz

By default an SMP vanilla kernel has 8 CPU support.
Max is 255.
