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.

The MATLAB Parallel Computing Toolbox and Distributed Computing Server are designed to allow users to create and launch parallel MATLAB jobs on a cluster of compute nodes. It also allows users to remotely connect to OSC resources, whether to run parallel jobs in MATLAB or to use toolboxes for which users own their own licenses. This guide will explain the basics of how to configure your Parallel Computing Toolbox for OSC systems.
The following versions of the MATLAB Parallel Computing Toolbox are supported at OSC:
ANSYS CFX (called CFX hereafter) is a computational fluid dynamics (CFD) program for modeling fluid flow and heat transfer in a variety of applications.
Availability and Restrictions
CFX is available on Oakley and Glenn Clusters. The versions currently available at OSC are:
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.
STAR-CCM+ provides the world’s most comprehensive engineering physics simulation inside a single integrated package. Much more than a CFD code, STAR‑CCM+ provides an engineering process for solving problems involving flow (of fluids and solids), heat transfer and stress. STAR‑CCM+ is unrivalled in its ability to tackle problems involving multi‑physics and complex geometries. Support is provided by CD-adapco. CD-adapco usually releases new version of STAR-CCM+ every four months.
OpenACC is a standard for parallel programming on accelerators, such as Nvidia GPUs and Intel Phi. It consists primarily of a set of compiler directives for executing code on the accelerator, in C and Fortran. OpenACC is currently only supported by the PGI compilers installed on OSC systems.
SuperLU is a library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. It comes in two different flavors: SuperLU_MT (multithreaded) for shared memory parallel machines and SuperLU_DIST for distributed memory parallel machines.
TurboVNC is an implementation of VNC optimized for 3D graphics rendering. Like other VNC software, TurboVNC can be used to create a virtual desktop on a remote machine, which can be useful for visualizing CPU-intensive graphics produced remotely.
Availability and Restrictions
TurboVNC is available on Oakley and Glenn Clusters. The versions currently available at OSC are:
