A simple step to energy efficient green HPC

While there are several technologies under development to maximize energy efficiency in HPC there are simple steps that can be taken with present technology to maximize energy efficiency and performance.

Use of optimized compilers and math libraries. A compute cycle wasted due to code inefficiency is a waste of energy, money and unrealized performance. Using an optimized compiler and math libraries will generate more efficient code and greatly reduced waste of compute resources and energy.

Some compiler vendors offer free use of their compilers for educational and non-profit users. Intel is one compiler vendor with such a program. Contact Western Scientific for more information.
