Computer science, in general, doesn&#8217;t have a conventional HPC cluster. We concentrate on GPUs and more specialized hardware. For large-scale HPC, OARC is the best source. They have a large cluster, Amarel. It is intended as a &#8220;condo&#8221; cluster. I.e., grants buy nodes and are guaranteed at least as much capacity as they purchased. The University matches the cost. However, some capacity is available for those who haven&#8217;t bought into the system, particularly for coursework and student use.<\/p><p style=\"padding-left: 40px\">For more information, see <a href=\"https:\/\/oarc.rutgers.edu\/\">the OARC website.<\/a><\/p><p style=\"padding-left: 40px\">Some of the OARC nodes have GPUs, typically Nvidia GPUs.<\/p><\/details><details><summary><b>Virtual machines<\/b><\/summary><p style=\"padding-left: 40px\">LCSR can provide virtual machines for researchers and for use by classes.<\/p><p style=\"padding-left: 40px\">Researchers commonly use VMs for web servers and other support services.

We can also create a limited number of VMs for grad students.
