The Deepthought HPC cluster (RETIRED)

The Deepthought High-Performance Computing (HPC) cluster is the first of the HPC clusters maintained by the Division of Information Technology as a general campus resource. After serving the campus research and academic community for over 10 years (albeit with the addition of hardware over that time), it was finally retired in May 2018 as the cost of maintaining as a reliable and viable cluster was outpacing its value as a research tool.

Hardware

The following table lists the variety of hardware that was on the Deepthought cluster, more or less from older to newer, at the time of its retirement.
