data link Story: New Worldwide Collaborations

New Worldwide Collaborations

Cactus also ties together various Alliance initiatives including the Globus Metacomputing Toolkit, PETSC, HDF5, GrACE, and Autopilot, as well as packages and projects such as 4D2, FlexIO, and Panda IO. This bringing together of applications is reflected in several major grants that have just been awarded or begun this year, all related to the Cactus projects.

• First is the Astrophysical Simulation Collaboratory project, funded by the NSF KDI program and involving researchers at Washington University, NCSA, the University of Chicago/Argonne National Lab, Rutgers University, and AEI. This project aims to further develop and integrate Cactus, Globus, GrACE, and other advanced computational tools to create a Grid-based collaborative infrastructure for interactive, large-scale simulation in Astrophysics. This technology will be applicable to many scientific and engineering communities requiring large-scale, collaborative simulation.
• Second is a recently announced European Network project that will use this technology for astrophysics and relativity research to explore black holes, neutron stars, and gravitational waves. This project is centered in Potsdam, but is distributed across ten of Europe's leading astrophysics and relativity groups in France, Germany, Great Britain, Greece, Italy, and Spain.
• Third is a Potsdam-based project involving AEI, Berlin's Konrad-Zuse-Institut (ZIB), and the Rechenzentrum-Garching (RZG) funded by Germany's DFN-Verein. This project is aimed at developing Cactus-based metacomputing applications exploiting high-speed networks for distributed and remote computing and visualization.
