Virtual Machines and Types of Service for TeraGrid Computing Foundational capabilities we provide in TeraGrid, such as "roaming" access and a "coordinated" software environment, open new possibilities in terms of more specialized services, or to allow the TeraGrid, as a system, to respond to supply and demand. For example, a resource provider might elect to increase the "price" of a queue in order to improve turnaround time by reducing demand, or decrease the price to increase demand (and thus utilization).
In a sharply worded speech to the Security Council this week, Russian President Dmitry Medvedev warned that Russia is "significantly behind" other countries in producing powerful supercomputers, and said the lag hurts Russia's competitiveness and its ability to defend itself.
I recently gave a presentation entitled "Cyberinfrastrucutre and its Role in Science" at IAI International Wireless Sensor Networks Summer School held at the University of Alberta on July 6th, 2009. This presentation examines some of the challenges scientists face and describes various cyberinfrastructure technologies that help address these challenges. Example projects employing cyberinfrastructure technologies that we have worked on at the Grid Research Centre, including the GeoChronos project, are also presented. Cyberinfrastructure and its Role in Science
Today, Rice University's network infrastructure is not sufficient to meet current academic, research, and operational demands. This system that used to enhance education, facilitate research, and support operations has now begun to be a significant obstac
we describe an end to end prototype environment that allows existing applications to run on the grid, taking advantage of open source software that provides a portal interface using GridSphere, with transparent GSI authentication using GAMA, a Web service
Cyberinfrastructure Technology Watch (CTWatch) is an online venue designed to engage the science and engineering research community in the news, ideas, and information surrounding the emergence of cyberinfrastructure as the essential foundation for advanc
