I plan to perform Linux installation (openSuSE 12.3/x86-64, kernel 3.7.10) for HPC-cluster. I want not to change CPU frequencies in cluster nodes, and not to use cpufreq kernel modules. Therefore I also don't want to use special power saving states of CPUs.
I performed fast test installation, and, of course, /lib/modules/`uname-r`/kernel/drivers/cpufreq directory is presented, but no cpufreq kernel modules are loaded, and /sys/devices/system/cpu/cpu0 e.a. do not have cpufreq files. But generally - must I perform special "steps" to avoid cpufreq modules load ? BTW, do somebody use acpid and/or cpupower RPM packages in cluster nodes ? If "yes", why they are interesting ?
