September 2019 Update: We have upgraded the HPC cluster with eight additional nodes to bring the total to 32 nodes with 768 total cores. The cluster from Aspen Systems consists of 32 identical nodes, each with two 12 core Intel Xeon processors and 128GB of RAM. The cluster includes 30TB of shared attached storage, all interconnected with an Infiniband switch. The cluster has a full suite of compilers installed, including open source GNU compilers and optimized Intel compilers, as well as MATLAB and other scientific applications.

Most recently the cluster has been used to run SPECFEM3D seismic wave propagation simulations, parallel MATLAB Hapke model optimization of lunar orbiter images, Bayesian Monte Carlo inversions, and ambient noise cross-correlation analyses of seismic array data. The cluster is primarily used by students, researchers and collaborators of faculty members Doug Wiens, Michael Wysession and Slava Solomatov. Students and collaborators with Brad Jolliff, Kun Wang and Bill McKinnon have also used the cluster.

The cluster can only be accessed via SSH from the local campus network. Anyone wishing to login remotely must do so using a VPN or by logging in through an externally accessible university server.
