SUMMARY:Bridging the Gap: User-Centric Energy Monitoring for Policy-Driven
  Application Optimization in HPC Data Centers
DESCRIPTION:Woong Shin (Oak Ridge National Laboratory (ORNL)); Karl W. Sch
 ulz (Advanced Micro Devices, Inc. (AMD)); Arthur F. Lorenzon (Federal Univ
 ersity of Rio Grande do Sul); Matthias Maiterth (Oak Ridge National Labora
 tory (ORNL)); Bruno Villasenor Alvarez and Jordà Polo (Advanced Micro Devi
 ces, Inc. (AMD)); Aditya Kashi, Hao Lu, Nicholson Koukpaizan, Antigoni Geo
 rgiadou, Matthew Norman, Wael Elwasif, Michael Matheson, and Feiyi Wang (O
 ak Ridge National Laboratory (ORNL)); Nicholas Frontiere (Argonne National
  Laboratory (ANL)); and Sarp Oral, Thomas Beck, and Bronson Messer (Oak Ri
 dge National Laboratory (ORNL))\n\nApplication energy optimization in HPC 
 data centers face two critical gaps. Systematic methodologies that connect
  data center policies to application decisions and accessible monitoring t
 ools that enable data-driven optimization. We address both gaps through tw
 o complementary pillars. First, we present a methodology based on extended
  weighted Energy Delay Product (EDP) to translate data center operational 
 priorities and integrate energy considerations into the energy optimizatio
 n workflow which starts from continuous monitoring through targeted optimi
 zation. Second, we present a user-space monitoring tool, Omnistat, that en
 ables this methodology by providing developers with direct access to actio
 nable energy telemetry. Through deployment on the Frontier supercomputer a
 nd case studies exploring performance-energy trade-offs, we show how these
  pillars help energy as an integral optimization target for developers as 
 active participants in data center efficiency.\n\nRecording: Livestreamed,
