SC22 BOF: HDF5 in the Era of Exascale and Cloud Computing


There will be a HDF5 BOF session at Supercomputing 2022 (SC22) on Wednesday, 16 November 2022 in the 12:15 pm - 1:15 pm CST session.

HDF5 is a pivotal I/O library for scientific applications. In this BoF, we will present new features that target exascale and “cloud HPC” environments, HDF5’s role in the ECP project, and the HDF5 roadmap. We will moderate a panel with representatives from research, commercial, and government organizations who will present case studies on how they use HDF5 for both cloud and exascale systems. This will provide a forum for users to discuss their experiences with HDF5, including new features to access data in object stores and the cloud. Session leaders will moderate open discussion with attendees and solicit feedback.
