SUMMARY:Lost in Translation: Interpreting Metrics in I/O Performance Analy
 sis Tools and Benchmarks.
DESCRIPTION:Radita Liem (Johannes Gutenberg University Mainz)\n\nI/O Perfo
 rmance analysis for modern HPC systems often involves a diverse ecosystem 
 of tools and benchmarks due to the multiple layers of abstraction in the p
 arallel I/O infrastructure. Despite various advances in instrumentation an
 d benchmarking technology, the resulting measurements rarely provide stake
 holders with a coherent end-to-end perspective on system behavior. Applica
 tion-level metrics and benchmark results are commonly gathered and interpr
 eted in isolation, making it difficult to connect the observed application
  performance to the characteristics of the underlying storage and I/O stac
 k. This talk explores where these disconnects emerge across the performanc
 e analysis workflow and discusses the need for a unified ecosystem that en
 ables holistic, context-aware interpretation of I/O performance.\n\nDomain
 : Climate, Weather, and Earth Sciences, Computational Methods and Applied 
 Mathematics\n\nSession Chairs: Ali Mohammed (HPE), Florina Ciorba (Univers
 ity of Basel), and Utz-Uwe Haus (HPE HPC/AI EMEA Research Lab)\n\n
