In 2009, ITC purchased Cerberus, a 256-core cluster. That translates to 32 nodes. Each node has 32 GB ram, giving an aggregate of 1TB. In addition, ITC has 74TB of total storage, 40TB of which is backed up nightly, with 34TB of 'scratch' space that is not backed up.

Cerberus is an addition to the FAS Odyssey cluster. The FAS cluster has over 11,000 cores and 1.5 PB of shared storage. Additionally, this cluster has access to licenses for Matlab, Mathematica, and IDL that can be used interactively on these machines. Users can get a VNC-like full desktop on the cluster. In addition, FAS Research Computing can host research websites and wiki sites. Some licensed software for linux, like MATLAB and Mathematica, are also distributed through the Research Computing website.

All users have access to FAS research computing staff members for help on software installation, debugging, and profiling questions. Please contact them at rchelp@fas.harvard.edu. For more information, please look at the FAS Research Computing website at http://rc.fas.harvard.edu. To gain access to Cerberus, fill out the web form at http://rc.fas.harvard.edu/request. Specify that you are a member of the ITC and include the name of your PI to receive access to the "itc" queue and storage.

Another option for those who want to run semi-large calculations is the Extreme Science and Engineering Discovery Environment (XSEDE) program coordinating access to 16 supercomputers and high-end visualization and data analysis resources across the country. While full usage proposals can be quite substantial, startup requests, on the order 50-100k hours, are easily obtained using the step-by-step instruction page at https://portal.xsede.org/web/guest/new-allocation.
