URC Data (Samba) Service

Posted on Wednesday, August 24, 2016 at 2:05 pm

Access to the URC Data Service (UDS) is available for those users who need to access their data from a remote client (on campus or via the campus VPN).  The UDS consists of server(s) which allow SMB-capable clients (i.e. MS Windows, macOS, and Linux) to mount remote shares as local drives (or mount points). Below are instructions for mounting a UDS share from various client machine types. Note that the UDS authenticates using Campus (NinerNET) passwords. read more »

Copperhead User Notes

Posted on Monday, August 1, 2016 at 2:41 pm

The Copperhead Cluster can be accessed via SSH to “hpc.uncc.edu.”  This will connect the user to one of the Interactive/Submit nodes located in the Copperhead Cluster pool.   From those nodes, a user can submit jobs requesting the following resources:

General Compute Nodes (54 x 16 cores ea = 864 procs)

GPU Compute Nodes (4 x 2 GPUS ea = 8 GPUs)

Large Memory Compute Nodes (1 x 768GB RAM)

Jobs should always be submitted to the “copperhead” queue unless directed otherwise by URC Support.

URC Mobile Website

Posted on Tuesday, August 17, 2010 at 11:42 am

We’ve recently revamped our website. Although it looks very much the same when you visit it from your desktop computer, one major change we’ve made is how the website is formatted for mobile devices. Mobile computing has been on the rise the past couple of years, so more and more of our users visit our site on their mobile devices. We wanted to make the site more “mobile friendly” for those visitors, so we implemented a system that redirects mobile users to a template that is formatted for them: read more »

Environment Modules

Posted on Monday, March 8, 2010 at 3:09 pm

What are Environment Modules?

The environment modules are a system that allows you to quickly and easily modify your shell environment to access different software packages. Research Computing offers a large (and growing) number of software packages to users, and each package may contain several tools, manual pages and libraries, or it may require special setup to work properly. Some software packages come in several versions or flavors, many of which conflict with each other. Modules allows you to tailor your shell to access exactly the packages you need by setting up the relevant environment variables for you, and automatically avoiding many possible conflicts between packages. read more »

Access to the URC File System is available for those users who need to access their home directory or project area from a remote client (on campus or via the campus VPN).

URC maintains a Samba server for each cluster which allows SMB capable clients (i.e. MS-Windows, MacOS X, and Linux) to mount remote shares as a local drive or mount point.  To obtain permission to use this server, send email to URCSupport@uncc.edu.

How do I Submit a Job?

Posted on Wednesday, May 7, 2008 at 2:53 pm

Most of the nodes in the URC cluster are accessed using the Condor job scheduling system which can accept both serial and parallel batch jobs. However, URC is transitioning away from Condor towards using Torque for job scheduling, so we would encourage you to use start using Torque instead of Condor. We have more information about submitting jobs to Torque on the URC cluster. read more »
