Core GT components address, within a common framework, fundamental issues relating to security, resource access, resource management, data movement, resource discovery, and so forth. These components enable a broader ＂Globus ecosystem＂ of tools and components that build on, or interoperate with, GT functionality to provide a wide range of useful application-level functions. These tools have in turn been used to develop a wide range of both ＂Grid＂ infrastructures and distributed applications. I summarize here the principal characteristics of the recent Web Services-based GT4 release, which provides significant improvements over previous releases in terms of robustness, performance,, usability, documentation, standards compliance, and functionality. I also introduce the new ＂dev.globus＂ community development process, which allows a larger community to contribute to the development of Globus software.展开更多

基金Work on Giobus has been supported in part by the Mathematical, Information, and Computational Sciences Division subprogram of the 0ffice of Advanced Scientific Computing Research, U.S. Department of Energy, under Contract W-31-109-Eng-38, by the National Science Foundation （NSF）＇s 0ffice of Cyberinfrastructure and other programs, and by IBM, DARPA, NASA, Microsoft, the UK Engineering and Physical Sciences Research Council and Department of Trade and Industry, and the Swedish Research Council. I report here on the work of many talented colleagues, as detailed at www.globus.org. The core team is currently based primarily at Argonne National Lab, U. Chicago, the USC Information Sciences Institute, U. Edinburgh, the Royal Institute of Technology, the National Center for Supercomputing Applications, and Univa Corporation, but many others have also contributed to Globus code, documentation, and testing, and/or made our work worthwhile by using the software.
