Bridges-2, a resource of Pittsburgh Supercomputing Center, is designed for converged HPC + AI + Data. Its custom topology is optimized for data-centric HPC, AI, and HPDA (High Performance Data Analytics). An extremely flexible software environment along with community data collections and BDaaS (Big Data as a Service) provide the tools necessary for modern pioneering research. The data management system, Ocean, consists of two-tiers, disk and tape, transparently managed as a single, highly usable namespace.
