How to configure Linux to boot less than installed number of processors?
Using the boot.ini and the /numprocs keyword, I can configure Windows to boot my 8-way server as a 1-way, 2-way, 4-way, etc. machine without having to physically remove any of the cpu's from the box. Is there a way to do with with Linux? I am using Redhat 7.3.
Thanks,
Rodney

Use "maxcpus=N" on the kernel boot/command line.
If you have a kernel source tree, see "linux/Documentation/kernel-parameters.txt" for all kernel boot parameters.

Useful info.

linux/Documentation/kernel-parameters.txt" for all kernel boot parameters.
It is a list of parameters, in many cases without any information on what they do or when/how to use them. My favorite is "init=" which is suggested to use during failed boot from Redhat installs.

Yes, it's not a complete, freestanding document of kernel parameters and their uses.

Hallo,
maybe a better source of information is
http://www.linux.org/docs/ldp/howto/BootPrompt-HOWTO.html
Well commented and fairly up to date.
Regards,
Burkhard Bunk.
