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
I didn't mean any special insult to the latest top 500 entry. Rather, that
was a comment on the general nature of that list. Does anyone know,
off-hand, how often these big machines run with all compute nodes dedicated
to a single message-passing job? My guess is less than 1% of the time, and
Some apps scale upto several hundreds of thousands of cores. These are Gordon
Bell award apps, with sustained levels around the PF.

Another one not in this list is DCA++, which has been ported also to GPUs.

/lib/modules/`uname-r`/kernel/drivers/cpufreq directory is
