Established in 1987, the Ohio Supercomputer Center (OSC) is a partner of Ohio universities and industries, providing researchers with high performance computing, advanced cyberinfrastructure, research and computational science education services.

OSC is an organizational member of the Ohio Board of Regents’ Ohio Technology Consortium[1] and works with an array of statewide/regional/national communities, including education, academic research, industry, and state government. The Center's research programs are primarily aligned with three of several key areas of research identified by the state to be well positioned for growth and success: biosciences, advanced materials and energy/environment.

Prominent program areas at OSC currently include:

OSC is funded through the Ohio Board of Regents by the state operating and capital budgets of the Ohio General Assembly. OSC offices are located on the West Campus of The Ohio State University in Columbus, Ohio, United States.


OSC was established by the Ohio Board of Regents in 1987 as a statewide resource designated to place Ohio's research universities and private industry in the forefront of computational research. Also in 1987, the OSC networking initiative — known today as OARnet — provided the first network access to the Center’s first Cray supercomputer.

In 1988, OSC launched the Center’s Industrial Interface Program to serve businesses interested in accessing the supercomputer. Battelle Memorial Institute, located just south of Ohio State, became OSC’s first industrial user. Today, the Center continues to offer HPC services to researcher in industry, primarily through its AweSim industrial engagement program.

In the summer of 1989, 20 talented high school students attended the first Governor’s Summer Institute. Today, OSC offers summer STEM education programs through Summer Institute and Young Women's summer Institute, which began in 2000.

Later in the fall of 1989, OSC engineers installed a $22 million Cray Y-MP8/864 system, which was deemed the largest and fastest supercomputer in the world for a short time.[2] The seven-ton system was able to calculate 200 times faster than many mainframes at that time.
