HEPnOS

HEPnOS is the High-Energy Physics's new Object Store, a distributed storage system specially designed for HEP experiments and workflows for the FermiLab. It relies on libraries developed at Argonne National Laboratory within the context of the Mochi project (ANL, CMU, LANL, HDF Group). The following pages will guide you through the installation and deployment process, and the user interface.

Note that the current version of HEPnOS is designed as a single-user, transient object store (that is, the user is also the administrator, and the data stored in HEPnOS won't be available after shutting it down). Future versions aim to become a multi-user, permanent object store, hence the following tutorials are divided between Administrator and Users.

Administrator

• Installing
• Deploying

Users

• Data organization
• DataStore and DataSets
• Runs, SubRuns, and Events
• Storing/loading C++ objects
