SUMMARY:Co-Design at System and Component Level:  Examples from the DEEP a
 nd EPI Projects
DESCRIPTION:Workshop\n\nEstela Suarez (Juelich Supercomputing Centre (JSC)
 )\n\nOptimizing the configuration of HPC systems to meet user requirements
  requires in-depth knowledge of application profiles and hardware limitati
 ons. A quantitative methodology, founded on the development of application
 -based benchmarks executed on representative hardware platforms, simulator
 s, and models, proves invaluable for this objective. Benchmarking sheds li
 ght on how application codes and their core components perform on HPC syst
 ems, enabling the identification of performance bottlenecks and opportunit
 ies for enhancement on the software side. Moreover, it aids in understandi
 ng the impact of specific hardware features on application performance, wh
 ether positive or negative. During this presentation, we will share our ex
 periences with benchmark-driven co-design approaches, derived from two Eur
 opean projects, namely DEEP and EPI. In DEEP, our focus was primarily on t
 he system level, while in EPI the target were on processor and core-level 
 aspects. We will describe the differences between both approaches and the 
 challenges that we found.\n\nTag: Codesign, Hardware Technologies, Large S
