Say for example a box has 8 CPUs, is there is a way logically to disable 4 CPUs? <BR /> Can it be done without physically removing the CPU from the box?<BR /><BR />Thnx<BR />SK<BR /> Tue, 25 Feb 2003 01:09:30 GMT https://community.hpe.com/t5/operating-system-linux/cpu/m-p/2912204#M3772 ShivKumar_1 2003-02-25T01:09:30Z https://community.hpe.com/t5/operating-system-linux/cpu/m-p/2912205#M3773 After the system is booted, I do not know.<BR /><BR />At a boot prompt, pass the argument:<BR /><BR />maxcpus=4<BR /><BR />This is documented in the linux kernel documentation in the file 'kernel-parameters.txt'.<BR /><BR />This is in the Documentation/ directory of the kernel source, or in the 'kernel-doc' package on a RedHat system.
