Computing Cluster

Students collaborating at a computer

In 2016, Dr. Olsen and Dr. Binkley from the computer science department, along with Dr. Albrecht from Chemistry and Dr. Schwartz from Economics, had an NSF MRI grant proposal funded to purchase a university-wide computer cluster.  A computing cluster is essentially a networked set of many computers, which can be used for computationally expensive tasks. Our computing cluster has is powered by Linux (CentOS 7), and has

  • 676 CPU cores spread across 29 compute nodes,
  • 10 nvidia Tesla K80 GPUs,
  • 256GB RAM per node, 7.4 terabytes of RAM in total,
  • 146 terabytes of disk storage,
  • 25 terabytes of fast SSD storage, and
  • 56 gigabit Infiniband network fabric

This computing cluster started its service in January 2017, and is available for any Loyola faculty member who needs access for a research project. Students working on research with faculty who use the cluster may also gain access to the cluster for the research project. Any faculty member who believes the cluster will be useful for their research, but isn’t sure, can contact Dr. Olsen to discuss if it could help their research. Any faculty member who wants access to the cluster, or needs assistance with using it, can contact System Administrator George Hall for an account.

The usage policies and information on how to connect to and run jobs on the cluster can be found on the cluster information page, which is only accessible from on-campus computers. Additionally, you can only SSH into the computing cluster from a campus computer, for security purposes.

As of 2019, the cluster has lead to the following publications, in addition to unlisted presentations and works in progress:
