FY27 budgets: Action may be required
- By default, the majority of budgets have an expiration of Tuesday, June 30, 2026.
- Most Ohio academic clients will need to set new budgets for FY27 before June 30 to avoid service disruption, depending on the project type as detailed below. FY27 is the period of July 1, 2026 through June 30, 2027.
OSC offers a one hour seminar targeting faculty who are unfamiliar with OSC to introduce the Center and the services we provide. The aim of this seminar is to provide a brief overview of OSC, what computational patterns are good candidates to consider using our services, and to point at entry points to begin. We can offer this seminar on your campus, with slight modifications to suit the audience, but offer a copy of the materials here for individuals to review.
