Mini-Symposium on: Energy-efficient Computing on Parallel Architectures (ECO-PAR) Hosted at International Conference on Parallel Computing (ParCo2019) 10-13 September 2019 Prague, Czech Republic. ORGANIZERS Enrico Calore (INFN-Ferrara) [email protected] Nikela Papadopoulou (National Technical University of Athens) [email protected] Sebastiano Fabio Schifano (University of Ferrara and INFN-Ferrara) [email protected] Vladimir Stegailov (HSE Tikhonov Moscow Institute) [email protected] ABSTRACT The power requirements of large HPC facilities are becoming unsustainable for both technical and economic reasons. A significant fraction of the total cost of ownership of HPC installations available nowadays is already driven by the electricity bill, and the idea of charging users for the energy consumed by their applications is spreading. This requires to find disruptive, smart and effective solutions, both at level of hardware and software to maximize energy-efficiency and computing throughput of HPC systems within a given power envelop. Several recently developed processors, such multi- and many-cores CPUs, GPUs, FPGAs and SoCs (System on Chip) are engineered including features to improve computing energy-efficiency, e.g. higher level of parallelism; dynamic clock frequency adaptation; capability of switching off idle cores, etc. However, programming complexity and code portability can be affected by these choices, and computing efficiency (as well as energy-efficiency) can be disrupted if applications are not properly coded to exploit (or take into account) all of the hardware features, in the worst scenario, possibly increasing the time-to-solution and the energy-to-solution. In addition, the heterogeneity of modern compute nodes and systems, combined with the dynamic behavior of modern applications, require educated resource allocation and resource management techniques to achieve energy efficiency. This workshop aims to strongly encourage the exchange of experiences and knowledge in novel strategies to exploit, monitor, analyze, and optimize the energy-efficiency of recent computing systems. We focus on new trends including, hardware and software tools, scheduling and resource management techniques but also algorithm-design and techniques in general, able to minimize the energy-to-solution of workloads, and to reduce the energy required to operate computing systems. Relevant topics include (but are not limited to): Application profiling and analysis of energy requirements aimed to energy-efficiency optimizations Case studies of parallel applications optimization towards Energy-efficiency Case studies of parallel applications performance optimization under a power budget Power estimation, analysis and optimization for hardware and software systems Power and Energy-efficiency assessment of processors and accelerators including also FPGAs Programming models, tools, languages and compilers to support energy-aware computing Compiler and run-time tools aimed to increase energy-efficiency Resource management techniques for energy-efficiency Low-power parallel architectures (use and design) Energy-proportional systems Energy-efficient heterogeneous system and communication architectures CONTRIBUTIONS Extended abstracts of 2-4 page(s) should be submitted in electronic form by July 15th 2019. Proposals should be submitted in “PDF” format, and should clearly describe the contents of the proposed paper. The relevance and originality of the contribution must be highlighted, and the most important references included. At most four relevant keywords must be supplied.
