The GRB Library: Grid Computing with Globus in C

In this paper we describe a library layered on top of basic Globus services. The library provides high level services, can be used to develop both web-based and desktop grid applications, it is relatively small and very easy to use. We show its usefulness in the context of a web-based Grid Resource Broker developed using the library as a building block, and in the context of a metacomputing experiment demonstrated at the SuperComputing 2000 conference.
