HPC clusters at ISU
Several HPC clusters (listed in the Systems & Equipment section) are available to ISU users.
Access to all HPC clusters is managed through Account Services on the Web (ASW) access lists.
The Education cluster supports classroom instructions. The instructors on record can request access to the Education cluster for themselves and the students taking their classes via this form. Once the class list is added to the Education cluster ASW access list, students can login to the cluster. This cluster is funded by the university.
Research clusters are funded both by the University and the individual PIs, as well as Colleges/Departments. Central funds cover infrastructure (interconnects, racks) and running of the cluster (electricity, cooling, system support), while PIs and some units purchase nodes and storage. Groups that purchased computing resources have a percentage share of the machine based on computing assets purchased by that group. However users in those groups are not limited to nodes that they purchased and can run computations on any compute node on the cluster, including fat and GPU nodes. PIs can manage access for their students and collaborators at the ASW website by adding and/or deleting users to/from appropriate ASW access list.
A new HPC cluster is purchased every 2.5-3 years with 5 year hardware warranty. Existing and new PIs can continue purchasing nodes after the initial cluster purchase. When a cluster is no longer under warranty, hardware is moved to the Free Tier and can be used by all users. Faculty can request access to the Free Tier for them and their students by filling out the form here. A new ASW access list is created for every group. PIs, that already have access to a cluster, can manage access for their group members at Account Services on the Web (ASW) website by adding and/or deleting users to/from appropriate ASW access list.
