Need to save a little energy?

Not everyone has a supercomputer lying around, especially an idle one, but if you have a high performance system and are looking to save some energy without losing much performance, Los Alamos National Laboratory might have the solution. With the use of EnergyFit 1.0, LANL is claiming a potential 10-25% energy savings in system energy consumption. According to this mobile piece from LinuxHPC.org, EnergyFit is

a transparent software layer based on a novel algorithm that reduces the power and energy consumption of high-performance computing systems.

Developed by Chung-Hsing Hsu and Wu-chun Feng at LANL, this software is another approach to addressing the enormous energy consumption and heat distribution of multiple processor architectures. Reducing the amount of energy used and consequent head produced by big machines leads, among other things, to a decrease in MTBF (mean time between failure) of processors and an increase in overall system reliability.

More information about power consumption and savings on large systems can be found in this Computerworld article.
