Farber (farber.hpc.udel.edu)

The Farber cluster, UD's second Community Cluster, was deployed in 2014 and is a distributed-memory, Linux cluster. It consists of 100 compute nodes (2000 cores, 6.4 TB memory). The nodes are built of Intel “Ivy Bridge” 10-core processors in a dual-socket configurations for 20-cores per node. An FDR InfiniBand network fabric supports the Lustre filesystem (approx 256 TiB of usable space). Gigabit and 10-Gigabit Ethernet networks provide access to additional filesystems and the campus network. The cluster was purchased with a proposed 4 year life, putting its retirement in the July 2018 to September 2018 time period.

The cluster has been named in honor of David Farber, UD professor and Distinguished Policy Fellow in the Department of Electrical and Computer Engineering. Farber is one of the pioneers who helped develop the U.S. Department of Defense’s ARPANET into the modern Internet. His work on CSNET, a network linking computer science departments across the globe, was a key step between the ARPANET and today’s Internet. Today, Farber’s work focuses on the translation of technology and economics into policy, the impact of multi-terabit communications, and new computer architecture innovations on future Internet protocols and architectures. He was named to the Internet Society’s board of trustees in 2012.
