Problem description
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.

Quantum ESPRESSO (QE) is a program package for ab-initio molecular dynamics (MD) simulations and electronic structure calculations. It is based on density-functional theory, plane waves, and pseudopotentials.
Owens, Pitzer
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.
This knowledge base is a collection of important, useful information about OSC systems that does not fit into a guide or tutorial, and is too long to be answered in a simple FAQ.
TIP: Remember to check the menu to the right of the page for related pages with more information about Ruby's specifics.
On 10/13/2016, Intel Xeon Phi coprocessors on Ruby were removed from service. Please contact OSC Help if you have any questions or want to help get access to alternative resources.
Ruby was named after the Ohio native actress Ruby Dee. An HP built, Intel® Xeon® processor-based supercomputer, Ruby provided almost the same amount of total computing power (~125 TF, used to be ~144 TF with Intel® Xeon® Phi coprocessors) as our former flagship system Oakley on less than half the number of nodes (240 nodes). Ruby had has 20 nodes are outfitted with NVIDIA® Tesla K40 accelerators (Ruby used to feature two distinct sets of hardware accelerators; 20 nodes were outfitted with NVIDIA® Tesla K40 and another 20 nodes feature Intel® Xeon® Phi coprocessors).

STAR-CCM+ is fully migrated from the Owens cluster to the Cardinal cluster on December 17, 2024.
Training is an important part of our services. We are working to expand our portfolio; we currently provide the following:
We provide a number of web portals for our user community.
OSC OnDemand is a "one-stop-shop" for accessing OSC compute resources. You can submit and monitor jobs, manage files, open terminal sessions and even get a desktop. Full documentation is available.
Description
This two hour workshop will provide an introduction to OSC resources and how to access them. Topics include:
- High performance computing concepts.
- Hardware and software available at OSC.
- Getting allocations and accounts.
- How to connect and log in.
- How to move data on and off the systems.
- Introduction to batch processing.
- Storage and file systems.

OSC offers online and in-person training for new and advanced users on a variety of high performance supercomputing topics.
New! Online Training Courses
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:
