Programming Frameworks for Optimized Software Composition for Parallel Systems

EXCESS (Execution Models for Energy-Efficient Computing Systems) is a European research project funded by EU FP7 2013–2016. The EXCESS project developed a holistic approach to energy optimization across the entire hardware/system software/application software stack. Targeting architectures and applications in both HPC and the embedded domain, its goal has been to bridge the gap between such systems and their tool chains by providing a generic, retargetable framework for programming and optimization. Work package WP1 of EXCESS, led by Linköping University, Sweden, investigates execution, platform and programming models for energy optimization. This presentation gives a high-level overview of the EXCESS programming and optimization framework.
