SUMMARY:Harmony: Converged Supercomputer Scratch and Archival Filesystems
DESCRIPTION:Jake Carroll (The University of Queensland)\n\nIn high-perform
 ance computing, scratch storage holds intermediate data while archival sto
 rage holds long-term data. These distinct objectives lead to separate impl
 ementations, implying additional costs and requiring explicit data transfe
 rs. This separation is inefficient, reduces reliability, and increases com
 plexity. We propose a policy-driven, unified solution that reconfigures ex
 isting technologies for seamless adaptation between modes. Our synthetic a
 nd real-world benchmarks demonstrate that naively combining scratch and ar
 chive degrades performance by 35%. However, our policy enhancements elimin
 ate this performance difference while maintaining system stability.\n\nTag
