Our website is powered by the HUBzero® software, a UC San Diego project. HUBzero was specifically designed to help a scientific community share resources and work together with one another. Users can upload their own content--including tutorials, courses, publications, and animations--and share them with the rest of the community. But each hub is more than just a repository of information. It is a place where researchers and educators can collaborate in private spaces to build simulation/modeling tools, gather datasets, and share them online. Users can launch computations and view results with an ordinary web browser--without having to download, compile, or install any code. The tools they access are not just web forms, but powerful graphical tools that support visualization and comparison of results.
At its core, a hub is a web site built with many familiar open source packages--the Linux operating system, an Apache web server, a MySQL database, PHP web scripting, and the Joomla content management system. The HUBzero software builds upon that infrastructure to create an environment in which researchers, educators, and students can access simulation tools and share information. Specifically, we define a "hub" as a web-based collaboration environment with the following features:
