The Deepthought HPC cluster

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. Over its 10 years of existence, it has been continually grown and refreshed, so while it is not as powerful as its larger sibling, it is still quite useful for smaller jobs and more High-Throughput Computing tasks.

Hardware

The following table lists the variety of hardware on the Deepthought cluster, more or less from older to newer.
