Linux Cluster Hardware

Hardware description of euler.phys.cmu.edu, the small linux cluster operated by the Widom research group in the CMU Physics Department.

Networking

The head node is named euler.phys.cmu.edu, with a webserver alias alloy.phys.cmu.edu hosting the alloy database. The file server is eulers.phys.cmu.edu. Authentication is via internal user names and passwords and via the CMU Andrew system. All nodes are connected internally by a gigabit network switch. Nodes euler and eulers are connected to the Wean Hall public network.

GPU

g01 has one Tesla K80 for running GPU-accelerated VASP. g02 has two Tesla K40 GPU's.

Storage

The file server eulers has 16TB on a RAID array serving the /home directories on the cluster. The file server runs a backup program tob, backing up to the head node euler. Usage is described in /home/alloy.db/HOWTO.restore. Each compute node has temporary free disk space in /tmp.
