It is with some sadness but also with much anticipation that we are announcing the end of Service for NCSA’s Nebula cluster. It’s replacement, the new Radiant cluster, is available for use and will provide greatly expanded capabilities from Nebula while keeping a similar user interface. Information about the Radiant system is available at We also encourage everyone interested to join the Radiant/Openstack Slack discussion channel at
