Scalable Tools for the Analysis and Optimization of Energy Consumption in HPC (Score-E)

For some time, computing centres have been feeling the severe financial impact of the energy consumption of modern computing systems, especially in the area of high-performance computing (HPC). Today, the share of energy already accounts for a third of the total cost of ownership and is continuously growing.

The main objective of the Score-E project, funded under the 3rd "HPC software for scalable parallel computers" call of the Federal Ministry of Education and Research (BMBF), is to provide user-friendly analysis and optimization tools for the energy consumption of HPC applications. These tools (Scalasca, Vampir, Periscope, and TAU) will enable software developers to investigate the energy consumption of their parallel programs in detail and to identify program parts with excessive energy demands, together with suggestions on how to make improvements and to evaluate them quantitatively.

In addition, the project will develop models to describe energy-related aspects that are not directly measurable and to provide a powerful visualization of the measurement results. At the same time, the project will further develop and maintain the community instrumentation and measurement system Score-P that forms the common base of all four tools mentioned above. Training and support for the software will be offered by VI-HPS and will continue beyond the lifetime of the Score-E project itself.
