Emerging high-performance applications require the ability to exploit diverse, geographically distributed resources. These applications use high-speed networks to integrate supercomputers, large databases, archive storage devices, advances visualization devices, and/or scientific instruments to form network virtual supercomputers or metacomputers. While the physical infrastructure to build such systems is becoming widespread, the heterogenous and dynamic nature of the metacomputing environment poses new challenges for developers of system software, parallel tools, and applications. In this paper, the authors introduce Globus, a system that they are developing to address these challenges.
