Grid Projects In The US July 2008
Download as PPT, PDF1 like904 views
The document discusses several US grid projects including campus and regional grids like Purdue and UCLA that provide tens of thousands of CPUs and petabytes of storage. It describes national grids like TeraGrid and Open Science Grid that provide over a petaflop of computing power through resource sharing agreements. It outlines specific communities and projects using these grids for sciences like high energy physics, astronomy, biosciences, and earthquake modeling through the Southern California Earthquake Center. Software providers and toolkits that enable these grids are also mentioned like Globus, Virtual Data Toolkit, and services like Introduce.
