GLOBUS - A METACOMPUTING INFRASTRUCTURE TOOLKIT

The Globus system is intended to achieve a vertically integrated treat ment of application, middleware, and network. A low-level toolkit prov ides basic mechanisms such as communication, authentication, network i nformation, and data access. These mechanisms are used to construct va rious higher level metacomputing services, such as parallel programmin g tools and schedulers. The longterm goal is to build an adaptive wide area resource environment (AWARE), an integrated set of higher level services that enable applications to adapt to heterogeneous and dynami cally changing metacomputing environments. Preliminary versions of Glo bus components were deployed successfully as part of the I-WAY network ing experiment.
