UKAN cluster list

Most machines may be reached by SSHing into the relavant domain name using their external ssh port. On the internal network, all SSH servers are running on port 22.

The UKAN clusters all share a common head, whose hostname is marl. Marl resides at 192.168.1.80 internally, and is also the landing point when sshing into super.ece.engr.uky.edu on port 22. All cluster nodes and cluster heads mount their home directory from marl. In addition to marl, each cluster has on interactive node, which is stateful and has a hard disk. These IP addresses for these nodes are listed in the table below. The head nodes have a much larger selection of software installed. In addition to mounting /home from marl, each cluster node mounts /chome from its cluster head. The /chome/[username] directory can be used for cluster specific files.
