Abstract

Core Globus services. As of early 1998, these include only those services deemed essential for an evaluation of the Globus design philosophy on realistic applications and in medium-scale grid environments. Other services such as accounting, instrumentation, and auditing will be addressed in future work.
The toolkit comprises a set of components that implement basic services for security, resource location, resource management, communication, and so on. As noted in Section 2.4, computational grids must support a wide variety of applications and programming models. Hence, the Globus toolkit provides a" bag of services"(as summarized in Table 11.1) from which developers of specific tools or applications can select to meet their needs. Because such services are distinct and have well-defined interfaces, they can be incorporated into applications or tools in an incremental fashion. We illustrate this characteristic in Section 11.8, where we show how a large, distributed, interactive simulation code can be made progressively more" grid aware" by incorporating first security and resource management, then resource location, then communication services, and so on.
