Globus: a Metacomputing Infrastructure Toolkit

TLDR: The Globus system is intended to achieve a vertically integrated treatment of application, middleware, and net work, an integrated set of higher level services that enable applications to adapt to heteroge neous and dynamically changing metacomputing environ ments.

Abstract: The Globus system is intended to achieve a vertically integrated treatment of application, middleware, and net work. A low-level toolkit provides basic mechanisms such as communication, authentication, network information, and data access. These mechanisms are used to con struct various higher level metacomputing services, such as parallel programming tools and schedulers. The long- term goal is to build an adaptive wide area resource environment AWARE, an integrated set of higher level services that enable applications to adapt to heteroge neous and dynamically changing metacomputing environ ments. Preliminary versions of Globus components were deployed successfully as part of the I-WAY networking experiment.
