Abstract
Abstract We describe the first major public data release from cosmological simulations carried out with Argonne’s HACC code. This initial release covers a range of data sets from large gravity-only simulations. The data products include halo information for multiple redshifts, downsampled particles, and lightcone outputs. We provide data from two very large ΛCDM simulations as well as beyond-ΛCDM simulations spanning 11 cosmologies. Our release platform uses Petrel, a research data service, located at the Argonne Leadership Computing Facility. Petrel offers fast data transfer mechanisms and authentication via Globus, enabling simple and efficient access to stored data sets. Easy browsing of the available data products is provided via a web portal that allows the user to navigate simulation products efficiently. The data hub will be extended by adding more types of data products and by enabling computational capabilities to allow direct interactions with simulation results.
