Energy Efficiency in HPC

The operating costs of High Performance Computing systems are considerable. The energy costs take up a notable proportion. There are different approaches to improve energy efficiency in HPC. The main focus of our research is in the area of ​​system software and applications. With the help of the development system of the HLRN III (Cray XC40), we are able to compare and to optimize the energy efficiency of different algorithms. In addition, we use a lab of ODROID-XU3 single chip computers. These small systems have next to 8 cores and a GPU in particular sensors for measuring the power consumption in real time. With respect to these systems, we have direct knowledge sharing with the Barcelona Supercomputing Center (BSC). The BSC is currently the world leader in the construction of HPC prototypes that allow to go new ways in the field of energy efficiency.
