Cluster Computing

Cluster Computing icon

As a leader in high performance computing and networking, OSC is a vital resource for Ohio's scientists and engineers. OSC’s cluster computing capabilities make it a fully scalable center with mid-range machines to match those found at National Science Foundation centers and other national labs.

OSC provides statewide resources to help researchers making discoveries in a vast array of scientific disciplines. Beyond providing shared statewide resources, OSC works to create a user-focused, user-friendly environment for our clients.

Collectively, OSC supercomputers provide a peak computing performance of 4,690 teraflops (CPU only). The center also offers more than 14.0 petabytes of disk storage capacity distributed over several file systems, plus 5.5 petabytes of backup tape storage.

Getting Started

To request a fully subsidized account you must be a full-time faculty member or research scientist at an Ohio college or university. Graduate students, postdoctoral researchers, lab members and other colleagues seeking access to OSC resources must be working with an eligible primary investigator.

Available Software

OSC has a variety of software applications to support all aspects of scientific research as well as licenses via our statewide software program.

Getting Started

Welcome to OSC! If you are new to supercomputing, new to OSC, or simply interested in getting an account (if you don't already have one), we have some resources to help you.

Technical Support

OSC provides experts to assist with individual client requests from a 24/7 support desk to Level 2 advanced support. 

Gateways

With OSC OnDemand for managing compute resources to the My.OSC administrative site, OSC provides a number of web portals for ease of access.  

Facilitation

OSC facilitators focus on research support, education and outreach to provide key services to Ohio’s academic and industrial research communities.
