Exploring the Proactive Data Containers Runtime System in VAST - A Case Study
DescriptionProactive Data Containers (PDC) is an object-centric runtime metadata and data management system designed for transparent, asynchronous, and autonomous data movement, taking advantage of the complex memory and storage hierarchy. We have previously explored PDC's performance and scalability with a traditional Lustre-based storage backend. Understanding PDC's behavior on novel storage solutions like VAST offers the chance to support cross-facility and multi-filesystem deployment for complex scientific analysis while preserving the key characteristics PDC was designed to attain. In this work-in-progress, we share our initial scalability results of PDC operations when running atop of a VAST data system.
