Welcome!

This site provides details of IT-supported hardware and software environments, instructions and tutorials on their use, and their organizational and administrative structure for the IT Research Computing community clusters. These community clusters are supported by the IT HPC Team.

To view all of the specific system information for active clusters including individual nodes and system status, see UD IT HPC.

The table below lists community clusters currently in service and supported by the IT HPC Team. The cluster documentation pages will have system information, a getting started guide, and specific documentation for that cluster. Visit the cluster specification pages for specific cluster configuration information.

Specifications Cluster Documentation Processor Available for Purchase Stakeholders

This wiki includes several types of instructional documentation

  • Instructions specific to each cluster such as system overview and specifications, getting started, transferring files, installing software, and running jobs can be found on the sidebar for each cluster.
  • The software-specific area contains local documentation that augments vendor-supplied documentation for application software.
  • The technical documentation area contains information authored by IT-NSS and IT-CSS as the HPC systems are built. This information is published to aid IT staff with future cluster deployments and to aid others who are building HPC systems.

Documentation conventions

In this wiki, the notational convention «name» indicates a placeholder whose value you supply. (You do not type the “«” or “»” symbols.)

Examples in the wiki using placeholder values

Placeholder Value
«hostname» mills.hpc.udel.edu
«username» traine
«investing_entity» it_css

Also Unix commands or commands specific to our cluster environment will be bolded, and defined terms specific to our cluster will be italicized.

Examples in the wiki using placeholder values, bolded commands and italicized terms

To use the compute nodes for a particular investing-entity cluster group (workgroup), you need to use the workgroup command.

workgroup -g «investing-entity»

For example, to start a new shell for the workgroup (investing-entity) it_css, type

    workgroup –g it_css

System problems or can't find an answer on this wiki

If you are experiencing a problem on one of the UD HPC community clusters, or you just can't find the help you need on this wiki, then submit a Research Computing Help Request specifying High-Performance Computing and choose the appropriate cluster for the problem details.

Ask or tell the HPC community

hpc-ask is a Google group established to stimulate interactions within UD’s broader HPC community and is based on members helping members. This is a great venue to post a question, start a discussion or share an upcoming event with the community. Anyone may request membership. Messages are sent as a daily summary to all group members. This list is archived, public, and searchable by anyone.

Publication and Grant Writing Resources

HPC templates are available to use for a proposal or publication to acknowledge use of or describe UD’s Information Technologies HPC resources.
