VIDIA is hosted at the Center for Computational Research (CCR), a leading academic supercomputing facility which maintains:
- high-performance computing (HPC) facilities
- high-end visualization laboratories
- cloud computing research environment
- support staff with expertise in computing, visualization, and networking
The Center’s extensive computing facilities, which are housed in a state-of-the-art 4000 square foot machine room, include an academic Linux cluster with more than 8000 processor cores and QDR Infiniband, a subset (32) of which contain (64) NVidia Tesla M2050 “Fermi” graphics processing units (GPUs). Industrial partners have access to a cluster with more than 3400 processor cores and FDR Infiniband. The Center maintains a 3PB IBM GPFS high-performance parallel file system. The computer visualization laboratory features a tiled display wall, and a VisDuo passive stereo system.
A leading academic supercomputing facility, CCR has more than 170 Tflops of peak performance compute capacity.
In addition to its computing and visualization resources, CCR has a support staff consisting of computational scientists, programmers, and database administrators with expertise in all areas of computing, including:
- scientific and parallel computing
- high-capacity data storage
- custom software development
- advanced database engineering
- grid computing
- scientific visualization
- cloud computing
CCR staff have extensive experience developing virtual organizations and analysis tools for high-performance computing users. CCR's expertise stems from their involvement with grid computing, in projects such as XSEDE and Open Science Grid, and XDMoD, and with collaborative virtual community building through the VHub HUBzero-based project.
VIDIA at CCR
The VIDIA site is powered by the HUBzero® Platform for Scientific Collaboration originally developed at Purdue University. 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.
How Does a Hub Differ From a Web Site?
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, a "hub" is a web-based collaboration environment with the following features:
- interactive simulation tools, hosted on the hub cluster and delivered to your browser
- simulation tool development area, including source code control and bug tracking
- videos and other supporting media for classes, tutorials, and documentation
- groups and projects for private collaboration
- mechanism for uploading and sharing resources
- user ratings and feedback for resources
- user support area, with question-and-answer forum
- statistics about users and usage patterns
