How many processor cores does my kernel support?

[jiandingzhe]

I'm using a server with two 6-core CPUs, which have 12 cores in total. Does Linux kernel supplies all these cores? How many processor cores does it support at the most?
My kernel version is 2.6.34.7-56.fc13.x86_64

What's the output of

cat /proc/cpuinfo

?

Linux kernel will support all the 12 cores of your CPU. It supports more than 250 CPU's, you can find the exact number of CPUs supported under your info file /usr/src/linux/Documentation. This file is present in your system.
