. In this article, we introduce Globus, a system that we are developing to address these challenges. The Globus system is intended to achieve a vertically integrated treatment of application, middleware, and network. A low-level toolkit provides basic mechanisms such as communication, authentication, network

-allocator components and defines an extensible resource specification language to exchange information about requirements. We describe how these techniques have been implemented in the context of the Globus metacomputing toolkit and used to implement a variety of different resource management strategies. We

of the architecture within the Globus metacomputing toolkit is discussed.

: This short note describes the use of LDAP in the Globus metacomputing toolkit. It answers three questions: What is LDAP? Where is it used? and Why is it used in the Globus metacomputing toolkit? Contents . Contents . 1. Short Introduction to Directory Services and LDAP . 2. Directory Service

systems using multi tier architecture with GLOBUS metacomputing toolkit as the backend of a middle tier of commodity web and object servers. We have demonstrated the fully functional prototype of WebFlow during Alliance'98 meeting.

such as brokering, monitoring, fault detection, and troubleshooting. Our architecture has been implemented as MDS-2, which forms part of the Globus Grid toolkit and has been widely deployed and applied.

report on the status of the Globus project as of early 1998. We describe the progress that has been achieved to date in the development of the Globus toolkit, a set of core services for constructing grid tools and applications. We also discuss on the Globus Ubiquitous Supercomputing Testbed (GUSTO

In this paper, we present a performance evaluation of a wide-area cluster system based ona rewallenabled Globus metacomputing toolkit. In order to establish communication links beyond the rewall, we have designed and implemented a resource manager called RMF (Resource Manager beyond the Firewall

components. We add high performance to commodity systems using GLOBUS metacomputing toolkit as the backend. Programming tools that are simultaneously sustainable, highly functional, robust and easy to use have been hard to come by in the HPCC arena. This is partially due to the difficulty in developing

software components. We add high performance to commodity systems using GLOBUS metacomputing toolkit as the backend. We have explained these ideas in general before, and here for the first time we describe a fully operational example which is expected to be deployed in an NCSA Alliance Grand Challenge.
