15. Quarry is still here!

16. Condominium computing – on Quarry Condominium computing - UITS-managed, departmentally owned research IT systems or system components: You can purchase nodes that are compatible with IU's Quarry cluster, have them installed in the very secure IUB Data Center, have them available when you want to use them, and have them managed, backed up, and secured by UITS RT staff. You get access to your nodes within seconds of requesting their use. When they are not in use by you, they become available to others in the IU community, thereby expanding the computing capability available to the IU community while conserving natural resources and energy.
