Energy consumption has become a major topic in high performance computing in the last years. This is first due to the high operational costs for large-scale machines which are almost as high as the acquisition costs of the whole installation. A second factor is the high carbon footprint of HPC-centers, which should be reduced for environmental reasons. We present the eeClust project, which aims at the reduction of energy consumption of applications running on a cluster with as little performance degradation as possible. We outline the concept of the project, present the tools involved in analyzing the energy consumption of the application as well as managing hardware power states. Further we present first results and the ongoing work in the project.
