We have added two login nodes to Glenn (opt-login05 and opt-login06), which are quad-socket computers with 64 GB of RAM. These were previously used as large memory nodes on Glenn, and will provide greater resources to the shared environment on the login nodes.
The ANSYS and ABAQUS modules on Glenn and Oakley have been modified to allow all users to select the base module instead of special modules, which was previously required for licensing purposes. For example, if you wish to use ANSYS 14 on Oakley, all users should load the ansys/14 module (not 14-com or 14-nimbis), and they will automatically be pointed at the correct license server.
The March 2014 HPC Tech Talk (Tuesday, March 18th from 4-5PM) will provide some brief OSC updates, have a user-driven Q&A session, and will close with a live demonstration of OSC's OnDemand service. You can register for the WebEX session here. Slides are available below.
The February 2014 SUG HPC Tech Talk focused on using the NVIDIA GPUs for computational chemistry. Slides are attached.
Here are the queues available on Glenn. Please note that you will be routed to the appropriate queue based on your walltime and job size request.

SSHing directly to a compute node at OSC - even if that node has been assigned to you in a current batch job - and starting VNC is an "unsafe" thing to do. When your batch job ends (and the node is assigned to other users), stray processes will be left behind and negatively impact other users. However, it is possible to use VNC on compute nodes safely.
The Ohio Supercomputer Center's IBM Cluster 1350, named "Glenn", features AMD Opteron multi-core technologies. The system offers a peak performance of more than 54 trillion floating point operations per second and a variety of memory and processor configurations. The current Glenn Phase II components were installed and deployed in 2009, while the earlier phase of Glenn – now decommissioned – had been installed and deployed in 2007.
