Using multiple energy gears in MPI programs on a power-scalable cluster
Recently, system architects have built low-power, high-performance clusters, such as Green Destiny. The idea behind these clusters is to improve the energy efficiency of nodes. H...

The potential in energy efficiency of a speculative chip-multiprocessor
While lower supply voltage is effective for energy reduction, it suffers performance loss. To mitigate the loss, we propose to execute only the part, which does not have any influ...

Run-time modeling and estimation of operating system power consumption
The increasing constraints on power consumption in many computing systems point to the need for power modeling and estimation for all components of a system. The Operating System ...
