What is about using of powersaved (and dbus and HAL daemons) on Beowulf nodes ? Currently I installed SuSE 10.3 where all the corresponding daemons are running (by default) at the runlevel=3. I simple added issuing of powersave -f at the end of booting. /proc/acpi/thermal_zone/ is empty, and powersave can't give me temperature and FANs information. I don't see now any serious advantages of powersaved daemon using in "performance" mode (using performance scheme). We have many jobs in SGE at every time moment, and underload situation (where it's reasonable to decrease CPUs frequency) is not the our danger :-) So I'm thinking about simple stopping of all the corresponding daemons.
