SUMMARY:Toward the Development of a Comprehensive Digital Twin of an Exasc
 ale Supercomputer
DESCRIPTION:Workshop\n\nWes Brewer (Oak Ridge National Laboratory (ORNL))\
 n\nOver the past year, we have embarked upon an ambitious initiative to de
 velop a comprehensive digital twin of the Frontier supercomputer. This twi
 n includes: 3D asset modeling with virtual and augmented reality capabilit
 ies, telemetry data assimilation, AI/ML integration, simulations, and rein
 forcement learning for optimization. Key simulations under development inc
 lude: (1) a transient simulation of the thermo-fluid cooling system from c
 ooling tower to cold plate, (2) a rectifier loss model predicting heat gen
 eration and rectification losses, (3) a job scheduling simulator, and (4) 
 a parallel discrete-event simulator to study network congestion. This digi
 tal twin offers insights into operational strategies, "what-if" scenarios,
  as well as elucidates complex, cross-disciplinary transient behaviors; it
  also serves as a design tool for future system prototyping. Built on an o
 pen software stack (Modelica, SST Macro, Unreal Engine) with an aim to fos
 ter community-driven development, we have formed a partnership with CSC Fi
 nland to study application fingerprinting on LUMI and are in active discus
 sions with a number of other supercomputer centers who have expressed inte
 rest in collaborating for future development.\n\nTag: Codesign, Hardware T
