HPC

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 will be posted here shortly before the event.

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.

Here are the queues available on Oakley. Please note that you will be routed to the appropriate queue based on your walltime and job size request.

Principal Investigators of OSC projects are responsible for updating their authorized user list, their outside funding sources, and their publications and presentations that acknowledge OSC. All of these tasks can be accomplished through the ARMSTRONG portal (https://armstrong.osc.edu). PIs are also responsible for monitoring their project's Resource Unit balance and for submitting a proposal to the Allocations Committee of the Statewide Users Group before the balance goes negative.

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 Ruby Transitional Cluster is a limited-access test cluster to explore Intel Xeon Phi accelerators and ideas we want to consider for our next production cluster. Ruby has 8 compute nodes, each with one Phi card.

OSC HPC resources use an operating system called "Linux", which is a UNIX-based operating system, first released on 5 October 1991. Linux is by a wide margin the most popular operating system choice for supercomputing, with over 90% of the Top 500 list running some variant of it. In fact, many common devices run Linux variant operating systems, including game consoles, tablets, routers, and even Android-based smartphones.

OSC has over two petabytes (PB) of disk storage capacity distributed over several file systems, plus almost 2PB of backup tape storage. (A petabyte is 10¹⁵, or a quadrillion, bytes.) This guide describes the various storage environments, their characteristics, and their uses.

Welcome to OSC! If you are new to supercomputing, new to OSC, or simply interested in getting an account (if you don't already have one), we have some resources to help you.
