In addition to our Linux Cluster, we operate a network of Linux compute servers. Their names can be listed on any SCF machine by typing 'sitehosts compute' and include aragorn (8 cores), arwen (32), gandalf (8), ghan(4), gollum(4), hermione(6), quidditch (8), radagast (8), and shelob (8). When ssh'ing, you would enter their fully qualified names, e.g., gandalf.berkeley.edu. Please read the policies on running jobs on the compute servers.
Of those machines, aragorn, gollum, hermione, quidditch, and shelob have the fastest CPUs, while gandalf and radagast have the most memory (132 GB).
