Since the center’s creation in 1987, the Ohio Supercomputer Center (OSC) has worked to propel Ohio’s economy, from academic discoveries to industrial innovation. The Center provides researchers with high-end supercomputing and storage, domain-specific programming expertise and middle school-to-college-to-workforce education and training.
Supercomputers are powerful, yes. But they are only as powerful as the codes researchers write for them. Brian Guilfoos, HPC client services manager at the Ohio Supercomputer Center, understands that high performance computing isn’t always intuitive and that education and training are essential services.
The Web and Interface Applications Group controls the way in which OSC HPC clients access and use most OSC systems.
When the Ohio Supercomputer Center was established through a state operating budget bill in 1987, it was “intended that the center be made accessible to private industry as appropriate.” Later that year, the Ohio Board of Regents created the Center “as a statewide resource designed to place Ohio’s research universities and private industry in the forefront of computational research.” Making thi

Since the creation of the Ohio Supercomputer Center (OSC) in 1987, the center’s staff has provided the critical services that allow Ohio researchers, professors and students to achieve great new levels of success, from empowering amazing scientific discoveries to partnering on remarkable industrial innovations.
When we think of supercomputing resources, we automatically think of processors and petaflops. However, compute capacity is only one part of the equation; software is another important component.
Virtual environments, once seen only as a unique extension of gaming technology, now are considered essential tools for competitiveness, from healthcare to education to manufacturing. The Ohio Supercomputer Center’s Virtual Environments and Simulation Group use this technology to create rich, precise, interactive simulations for training, assessment and remote collaborations.
Client Services is the entry point for our user community. We provide the connections to the services that OSC offers its clients, and we do that in a number of ways. We manage the administrative functions associated with research done here. We also provide the technical support through a recently expanded 24/7 help desk.
With the April dedication of OSC’s newest cluster, the Ohio Supercomputer Center currently is offering researchers three mid-sized high performance computing (HPC) systems: the HP/Intel Xeon Phi Ruby Cluster, the HP/Intel Xeon Oakley Cluster and the IBM/AMD Opteron Glenn Cluster.
