Up to how many CPUs can Linux support?In: Linux |
Unfortunately, there's not a simple answer to this. The Linux kernel can be compiled to support any number of CPUs. According to some distribution-specific support documents I found in researching this answer, the number ranges from 1-4, 64, 1024, and 'unlimited' in the case of Red Hat Enterprise Linux.
When the Kernel is compiled, there is a configuration directive passed to the compiler ('NR_CPUS') that determines the maximum number of CPUs supported.
My suggestion is to research your specific distribution and see what the developers compiled the kernel to support. It should be readily available on their documentation (I was able to find this easily for many common distributions).
