SUMMARY:Datacenter Power Monitoring and Management Using MERIC SW Suite
DESCRIPTION:Ondrej Vysocky (IT4Innovations National Supercomputing Center)
 \n\nAn HPC system can be optimized for energy efficiency at several levels
 , while the highest level of dynamicity comes from the power management of
  computing components controlled at the job level. Complex parallel applic
 ations show different hardware requirements during their execution. Energy
 -efficient runtime systems provide administrator- and user-friendly ways t
 o perform dynamic hardware power knobs management without requiring a deep
  understanding of the topic. MERIC energy-efficient HPC software suite is 
 a package of software tools for datacenter monitoring and optimization for
  power and energy consumption. The package includes cluster monitoring, jo
 b energy budgeting, cluster power capping applying a dynamic power limit a
 djusted based on the recent history of power consumption, and power manage
 ment. Its component is also the EuroHPC Center of Excellence Performance O
 ptimisation and Productivity (POP) flagship code MERIC, which is a job-lev
 el runtime system designed to provide a detailed analysis of application b
 ehavior, identify the optimal hardware settings concerning energy consumpt
 ion 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 cont
 rolled power knobs, it pushes the achievable energy savings to the limit.\
