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.



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.
