The Mills cluster, UD’s first Community Cluster, was deployed in 2012 and is a distributed-memory, Linux cluster. It consists of 200 compute nodes (5160 cores, 14.5 TB memory, 49.3 peak Tflops). The nodes are built of AMD “Interlagos” 12-core processors, in dual- and quad-socket configurations for 24- and 48-cores per node. A QDR InfiniBand network fabric supports the Lustre filesystem (approx 180 TB of usable space). Gigabit and 10-Gigabit Ethernet networks provide access to additional Mills filesystems and the campus network. The cluster was purchased with a proposed 5 year life, putting its retirement in the October 2016 to January 2017 time period.

The cluster was named to recognize the significant scientific and engineering contributions of Prof. Emeritus David L. Mills, Dept. of Electrical & Computer Engineering, UD.

This cluster is currently unavailable for purchase

  • Workgroup directory quotas start at 1 TB and scale in proportion to investment
Login nodes

Users connect to the cluster through two login nodes:

  • 2 x 24C AMD6234 (Interlagos) (48 cores)
  • 64 GB DDR4 memory (8 x 8 GB)
  • 1 x 10 Gbps uplink to campus network, Internet
  • 1 x 100 Gbps Intel OmniPath cluster network

The Mills cluster has been named in honor of David L. Mills, UD professor emeritus and a pioneer of the early Internet and its precursor networks. Mills was a professor in the University’s Department of Electrical and Computer Engineering from 1986-2008 and continues to teach and lead research sponsored by such agencies as the NASA Jet Propulsion Laboratory, Defense Advanced Research Projects Agency and National Science Foundation.
