Owens cluster will be decommissioned on February 3, 2025. Some pages may still reference Owens after Owens is decommissioned , and we are in the process of gradually updating the content. Thank you for your patience during this transition

An eligible principal investigator (PI) heads a project account and can authorize/remove user accounts under the project account (please check our Allocations and Accounts documentation for more details). This document shows you how to identify users on a project account and check the status of each user.
OSC's Owens cluster being installed in 2016 is a Dell-built, Intel® Xeon® processor-based supercomputer.
This guide was created for new users of OSC.
It explains how to use OSC from the very beginning of the process, from creating an account right up to using resources at OSC.
The first step is to make sure that you have an OSC username.
A common problem on our systems is that a user's job causes a node out of memory or uses more than its allocated memory if the node is shared with other jobs.
If a job exhausts both the physical memory and the swap space on a node, it causes the node to crash. With a parallel job, there may be many nodes that crash. When a node crashes, the OSC staff has to manually reboot and clean up the node. If other jobs were running on the same node, the users have to be notified that their jobs failed.
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.
OSC offers online and in-person training for new and advanced users on a variety of high performance supercomputing topics.
OSC has partnered with The Ohio State University to offer online training courses that clients can complete at their own pace at any time on the ScarletCanvas platform, Ohio State's public learning management system.
The first two available courses are:
Several commands allow you to check job status, monitor execution, collect performance statistics or even delete your job, if necessary.
There are many possible reasons for a long queue wait — read on to learn how to check job status and for more about how job scheduling works.
Use the squeue command to check the status of your jobs, including whether your job is queued or running and information about requested resources. If the job is running, you can view elapsed time and resources used.
Ohio Supercomputer Center (OSC) has a variety of software applications to support all aspects of scientific research. We are actively updating this documentation to ensure it matches the state of the supercomputers. This page is currently missing some content; use module spider on each system for a comprehensive list of available software.
