Research on low power systems has received a great amount of attention in recent years since the sustainability of current technologies and practices has become a serious issue. In the meantime, stiff increases in energy price and the environmental impact of carbon dioxide emissions associated with energy generation and transportation have forced the issue of reducing energy consumption to be extended to a broader range of system including High Performance Computing Systems (HPCS). Various issues such as resource management in both software and hardware levels must be addressed to reduce energy consumption in HPCS. An important issue in hardware resource management is how to reduce power usage in processors.
