Abstract:   Caught between the continuous technological advances and the global efforts for greener IT, power consumption of modern high performance computing systems has become a major challenge on the road to exascale computing. This workshop focuses on new energy-aware computing paradigms and programming methodologies to address the problem of prohibitive power consumption by current hardware when extrapolating to exascale machines. The goal of this workshop is to bring together scientists and engineers from academia and industry with interests in energy-efficient computing. Workshop topics include:
  • Tools for advanced power consumption monitoring and profiling.
  • New multi-objective metrics for quantitative assessment and analysis of the energy profile of algorithms.
  • Smart algorithms using energy-efficient software models.
  • Power-aware implementations of numerical methods for high performance clusters.
  • Performance/energy optimisation in applications, showcases, proof of concepts.
Target Audience
Researchers, industry, HPC experts, hardware vendors, software engineers, simulation engineers, computer scientists, mathematicians, physicists, interested in power consumption.
