Abstract:
Data center operators, as well as their users, face pressure to constantly evaluate and optimize energy efficiency and the sustainability of computation. The MERIC energy-efficient HPC software suite is a package of software tools for data center monitoring and optimization for power and energy consumption. The package includes cluster monitoring, job energy budgeting, cluster power capping applying a dynamic power limit adjusted based on the recent history of power consumption, and power management. Its component is also the EuroHPC Center of Excellence Performance Optimization and Productivity (POP) tool MERIC, which is a job-level runtime system designed to provide a detailed analysis of application behavior, identify the optimal hardware settings concerning energy consumption and runtime, and provide dynamic tuning during the application runtime. Thanks to complex execution time coverage by regions of interest, tuning granularity at the level of tens of milliseconds, and a large set of controlled power knobs, it pushes the achievable energy savings to the limit.
Short Bio:
Ondřej Vysocký, Ph.D., is a Senior researcher at IT4Innovations in the Infrastructure Research Lab, leading the energy-efficient HPC research group. He was an investigator of the Horizon 2020 READEX project, which dealt with the energy efficiency of parallel applications using dynamic tuning. Since that time, he has developed a MERIC energy-efficient software suite for data centers’ power monitoring and management. Using MERIC tools, he is an investigator of several Horizon 2020 and Horizon Europe projects, including EuroHPC Centers of Excellence. He is also a member of the ETP4HPC, EE HPC WG, and HPC PowerStack initiatives, which bring experts from around the world to focus on power consumption challenges in the HPC field.
