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 7.5 Petaflops (PF). The center also offers approximately 16 Petabytes (PB) of disk storage capacity distributed over several file systems, plus more than 14 PB of available backup tape storage (with the ability to easily expand to over 23 PB).

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

What can OSC do for you? 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 support desk to Level 2 advanced support. 


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


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

Protected Data Service

OSC's Protected Data Service (PDS) is designed to address the most common security control requirements encountered by researchers while also reducing the workload on individual PIs and research teams to satisfy these requirements.

Security, Accessibility, and Policies

OSC is regularly audited for security standards and abides by OSU's digital accessibility standards. OSC also supports export controlled and HIPPA projects.

OSC Campus Champions

The Ohio Supercomputer Center’s (OSC) Campus Champions program is composed of high performance computing (HPC) advocates at academic institutions across the state. Campus Champions serve as local proponents for access and utilization of OSC resources on their campuses.
