Harmony: Converged Supercomputer Scratch and Archival Filesystems
DescriptionIn high-performance computing, scratch storage holds intermediate data while archival storage holds long-term data. These distinct objectives lead to separate implementations, implying additional costs and requiring explicit data transfers. This separation is inefficient, reduces reliability, and increases complexity. We propose a policy-driven, unified solution that reconfigures existing technologies for seamless adaptation between modes. Our synthetic and real-world benchmarks demonstrate that naively combining scratch and archive degrades performance by 35%. However, our policy enhancements eliminate this performance difference while maintaining system stability.
