Unity: Read Me First


Unity is the College of Arts and Sciences' high-performance computing (HPC) cluster. It can be used free of charge by any researcher in the college. Currently we have about 100 compute nodes; about half the nodes were purchased by the college (these are available for any college researcher's use) and the other half by individual researchers (these may be reserved for that research group's exclusive use or may be shared with other Unity users). This article is intended to get you started using Unity and direct you to other documentation.

Getting an account

You use your OSU account (name.#) to access Unity but we need to add your account to the group that can access Unity before you can log in.

Request access to Unity.

Logging in

Unity is a Linux-based system with a command-line interface. You can use ssh on your computer to log in to Unity.

From a Windows, Mac or another Linux system connected to an ASC network, you can type 

$ ssh name.#@unity.asc.ohio-state.edu 

at a command prompt (substitute your name.# for name.#).

Windows users have historically used PuTTY (available in Software Center on ASC computers, or download the PuTTY package for personally-owned computers), but Windows 10 now includes an ssh client.

If you are not on an ASC network (for example, from OSU Wireless or from home), you’ll need to connect through ASCTech's jump host (preferred) or connect to the ASC VPN first. 

Going further

You may want to look at our walk-through of typical Unity usage.

We also have a help section of frequently-asked questions, how-to guides and best practices to help you get the most out of Unity.

Unity is modeled after clusters at the Ohio Supercomputer Center (OSC); much of OSC's documentation is also relevant. You'll find links to this and more in our References section.
