Original Dell C8000 Argo Nodes.

The Office of Research Computing administers a 1500+ CPU core batch-processing cluster called ARGO and a new cluster called HOPPER (currently with 3680 cores) available to all GMU faculty and faculty-sponsored students.

The ARGO and HOPPER clusters are both based on the condo model. However there are differences in how this "condo" model is implemented:

  • Contributors buying nodes for the ARGO clusters are provided higher priority access to the whole cluster and temporary exclusive access to the funded nodes by arrangement.
  • Contributors buying nodes for the HOPPER clusters are provided preemptive access to funded nodes.
