Open OnDemand

Open OnDemand Logo

Open OnDemand is an NSF-funded (#1534949), open-source HPC portal developed by OSC, based upon the Center’s original OnDemand portal. The goal of Open OnDemand is to provide an easy way for system administrators to provide web access to their HPC resources.

The 1.0 version of Open OnDemand, launched in September 2017, includes the ability to launch interactive HPC desktop sessions with the new dashboard “batch connect” plugin, support for Portable Batch System Professional’s (PBS Pro) workload manager and job scheduler software and partial support for IBM’s Load Sharing Facility (LSF) 9.1 workload management platform.

Going forward, OSC is interested in adding support for additional popular apps, such as Jupyter, RStudio, COMSOL Server, MATLAB, Paraview, ANSYS and Abaqus.

AweSim provides manufacturers with competitive solutions for simulation-driven design. We help to automate the prototyping process and provide affordable, accessible, and scalable M&S on HPC via:

  • Online modeling and simulation apps and tools
  • Educational materials and training courses
  • Industry-specific expertise and consultants

AweSim is a program of the Ohio Supercomputer Center, who along with M&S industry experts are pioneering the field of M&S -as-a-service.


WebMO Logo

WebMO is a free World Wide Web-based interface to computational chemistry packages.

WebMO improves the accessibility and usability of computational chemistry software. Users can access and use your software from their web browser. A web-based interface provides unheard of ease-of-use and a shallow learning curve for beginners. Advanced users benefit from convenience, full access to input and output, and management of computing resources. WebMO also allows many users to take advantage of a single workstation on which the computational chemistry programs are installed. This greatly lowers the cost of hardware and software licenses, and it minimizes the time and effort for system maintenance.

TS Aero

TotalSim Logo

TS Aero is a web interface for performing computational fluid dynamic (CFD) simulations on Aircraft, UAV's, Drone, and Multi-copters.

Users of the app are be able to upload geometry, configure and run their CFD simulation, and analyse forces and flow on their vehicles all inside the application. TS Aero provides a suite of post-processing results that can then be compared across designs and conditions for insight on trends and performance -results can also be downloaded for further offline analysis.

The Opacity Project

Opacity Project Logo

The name Opacity Project (OP) refers to an international collaboration that was formed in 1984 to calculate the extensive atomic data required to estimate stellar envelope opacities and to compute Rosseland mean opacities and other related quantities.

It involved research groups from France, Germany, the United Kingdom, the United States and Venezuela. The approach adopted by the OP to calculate opacities is based on a new formalism of the equation of state and on the computation by ab initio methods of accurate atomic properties such as energy levels, f-values and photoionization cross sections.
