Hubzero is a platform used to create dynamic web sites for scientific research and educational activities. With Hubzero, you can easily publish your research software and related educational materials on the web. A hub combines unique middleware with Web 2.0 functionality, providing a platform that is much stronger than an ordinary website. Users will not only be able to network and share information but also create, publish and access interactive visualization tools powered by a rendering farm and other cluster computing resources, as well as engage in online collaboration fostering the development of an educational community. HUBzero was created by the NSF-funded Network for Computational Nanotechnology starting in 2002 with the development of their hub at nanoHUB.org. Since then, usage of nanoHUB.org has grown exponentially. In 2009, nanoHUB.org served 274,000 visitors from 172 countries worldwide.
