New User Resource Guide

Welcome to OSC! This document provides some useful links to get you started.

If you are new to supercomputing, or to OSC, please visit http://www.osc.edu/supercomputing/getting-started for information about how our supercomputers are configured, and some guidance about appropriate usage of the various resources.

Logging in to OSC resources is primarily accomplished via SSH (or “secure shell”). This is a method of getting a command line interface on the HPC, which is running a version of the Linux operating system. For more details on how to connect to our systems, please visit

            http://www.osc.edu/supercomputing/getting-started/getting-connected

If that sounds too intimidating, and you would like to try a zero-client web-browser approach to using OSC, you can log in to OnDemand:

            https://ondemand.osc.edu/

SFTP (Secure File Transfer Protocol) is the primary method of moving files to and from OSC storage systems. SCP (Secure CoPy) is another common method. Small files can be moved to and from OSC systems inside of OnDemand. Moving large files to or from OSC via the login nodes can experience difficulty, since there are compute restrictions on those nodes, so the recommendation is to connect to sftp.osc.edu, or scp.osc.edu. If you have a large amount of data to move, you can schedule transfers via Globus Online.

Batch scripts – instructions to be executed by the node(s) assigned to you when your request for resources can be met by the scheduler – can get very complicated, so it’s best to refer to the documentation for the software you want to use to get started.

We also have a more detailed guide on the batch system that we recommend new users read. It provides information about scheduling, and how to write scripts to accomplish various tasks.

You can find events at the center (including training) by visiting osc.edu/e , system notices are at osc.edu/n , we provide important information in the “message of the day” (visible when you log in), and you can get notices by following @HPCNotices on Twitter. Help can be found by contacting our help desk weekdays, 9AM to 5PM.
