OSC Starter Kit Users Manual

Introduction

This starter kit provides everything you need to get started on the Ohio Supercomputing Center's high-performance computing (HPC) systems. Using the WinSCP SFTP client and the Xming X-Windows server you will be able to transfer files, start terminal sessions with the our HPC clusters, and submit jobs to our scheduling system.

You can use these programs directly if you like, but we provide some helpful shortcuts in the “OSC Starter Kit” folder in your Start Menu:

  • “Connect to Glenn” and “Connect to Oakley”: Start terminal sessions with Glenn and, once active, Oakley. In these windows you can run programs and submit jobs to our scheduling system using the command-line interface. For more guidance, see “Further Reading” below.

  • “Transfer Files”: Provides a drag-and-drop interface for transferring files to and from the shared HPC filesystem.

The “OSC Starter Kit” Start Menu folder also contains a folder of links to helpful pages on the OSC website, including our account management and networking portal ARMSTRONG

System Requirements

The Starter Kit requires a computer running Windows XP or greater and at least 50MB of free disk space.

Installation

To install the starter kit, simply double-click on “Install OSC Starter Kit.exe” and follow the instructions. If you already have some of the provided programs installed, feel free to deselect them to avoid overwriting your settings. Be advised however that this may break the “Connect to...” and/or “Transfer Files” shortcuts.

Transferring Files

To upload files to your HPC home directory, click the Start Menu, navigate to the “OSC Starter Kit” folder, and click the “Transfer Files” link. You will be asked to enter your OSC username and password, after which a secure file transfer session will begin.

Once you have connected, a window will appear showing your HPC home directory. To transfer files, simply drag them onto this window. To transfer files from the HPC to your computer, drag them from the WinSCP window onto your desktop.

Connecting to the HPC clusters

To open a terminal session with one of our HPC clusters, open your Start Menu and navigate to ”OSC Starter Kit Connect to“ and select the cluster you wish to connect to. You will be prompted to enter your username and password. Once you have done so a terminal window will appear. This window will allow you to interact with your selected HPC cluster through a UNIX shell.

Note: All username and password prompts for the “Connect to” shortcuts will obscure your typing with dots, but only the first box will request your username. Be sure to type carefully. If you believe you've mistyped your username, simply press cancel and reopen to application.

Running Interactive Sessions

Some applications are too time- or resource-intensive too run on the login nodes. If these jobs can be automated, they should be submitted using the
