SUMMARY:Enhancing Usability and Performance in Experimental Environments M
 anagement
DESCRIPTION:Zahra Temori (University of Delaware), Paul Marshall (UChicago
  Department of Computer Science), and Kate Keahey (Argonne National Labora
 tory (ANL))\n\nReproducibility is a challenge in HPC and research. HPC exp
 eriments are resource-intensive and depend on complex software environment
 s. Snapshotting addresses this issue, captures the complete state of a sys
 tem in a single step, allowing researchers to automatically rebuild and re
 store identical environments. However, concerns remain about snapshot effi
 ciency and usability. To improve snapshotting in HPC research, the tools n
 eed to be straightforward to use and perform quickly on large bare metal e
 nvironments. Therefore, we improved usability and evaluated the performanc
 e of cc-snapshot, a tool on the Chameleon Cloud testbed. Usability enhance
 ments included new command line options, modular code, and automated tests
 . To optimize performance, we benchmarked alternative image formats and co
 mpression algorithms. The results show that zstd delivered up to 80% faste
 r compression time during snapshot creation compared to zlib. These findin
 gs demonstrate that snapshotting can be a practical and effective tool to 
 support reproducibility in HPC experiments.\n\nTag: Research & ACM SRC Pos
