====== Welcome! ======
~~NOCACHE~~
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 [[itrc>community-cluster|IT Research Computing community clusters]]. These community clusters are supported by the [[itrc>contact|IT HPC Team]].
To view all of the specific system information for active clusters including individual nodes and system status, see [[http://www.hpc.udel.edu|UD IT HPC]].
===== Clusters =====
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.

===== Documentation =====
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:software|software-specific]] area contains local documentation that augments vendor-supplied documentation for application software.
* The [[technical:technical|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 <> indicates a placeholder whose value you supply. (You do not type the "<<" or ">>" symbols.)
=== Examples in the wiki using placeholder values ===
^ Placeholder ^ Value ^
| <> | mills.hpc.udel.edu |
| <> | traine |
| <> | 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'' <>
For example, to start a new shell for the workgroup (//investing-entity//) ''it_css'', type
workgroup –g it_css
===== Help =====
==== System or account problems, or can't find an answer on this wiki ====
If you are experiencing a problem on one of the UD HPC clusters, or you just can't find the help you need on this wiki, then submit a [[https://services.udel.edu/TDClient/32/Portal/Requests/TicketRequests/NewForm?ID=D5ZRIgFlfLw_|Research Computing High Performance Computing (HPC) Clusters Help Request]] and complete the form including which cluster and your problem details in the description field.
==== Ask or tell the HPC community ====
[[https://groups.google.com/a/udel.edu/d/forum/hpc-ask?hl=en-US|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 about HPC, 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 =====
For general acknowledgment of UD IT-RCI staff and HPC resources, please use the following text: "This research was supported in part through the use of Information Technologies (IT) resources at the University of Delaware, specifically the high-performance computing resources."
For Caviness and Farber, [[http://sites.udel.edu/research-computing/community-cluster-templates/|HPC templates]] are available to use for a proposal or publication to acknowledge use of or describe UD’s Information Technologies HPC resources.
For DARWIN, please refer to the [[https://nsf.gov/awardsearch/showAward?AWD_ID=1919839|NSF award]] information for a proposal or publication to acknowledge use of or describe DARWIN resources. We require all allocation recipients to acknowledge their allocation awards using the following standard text: “This research was supported in part through the use of DARWIN computing system: DARWIN – A Resource for Computational and Data-intensive Research at the University of Delaware and in the Delaware Region, Rudolf Eigenmann, Benjamin E. Bagozzi, Arthi Jayaraman, William Totten, and Cathy H. Wu, University of Delaware, 2021, URL: https://udspace.udel.edu/handle/19716/29071″
