GRIDBUS PROJECT STATUS
REPORT
Grids aim at exploiting synergies that result from cooperation of
autonomous
distributed entities. The synergies that result from Grid cooperation include
the sharing, exchange, selection and aggregation of geographically distributed
resources such as computers, data bases, software and scientific instruments
for solving large-scale problems in science, engineering and commerce. For
this cooperation to be sustainable, participants need to have economic
incentive. Therefore, "incentive" mechanisms should be considered as one of
key design parameters of Grid architectures. In this article, we present an
overview and status of an open source Grid toolkit, called Gridbus, whose
architecture is fundamentally driven by the requirements of Grid economy.
Gridbus technologies provide services for both computational and data Grids
that power the emerging eScience and eBusiness applications.
The Gridbus Project (www.Gridbus.org) at the University of
Melbourne,
Australia has been developing a computational economy/market-based Grid
technologies that helps in creating a service-oriented computing architecture
where service providers offer paid services associated with a particular
application and users, based on their requirements, would optimize by
selecting the services they require and can afford within their budget. To
realize this scenario, the Gridbus project is actively pursuing research in
the design and development of open source cluster and Grid middleware
technologies for utility and service-oriented computing. These include visual
Grid application development tools for rapid creation of distributed
applications, competitive economy-based Grid scheduler, cooperative economy-
based cluster scheduler, Web-services based Grid market directory (GMD), Grid
accounting services, Gridscape for creation of dynamic and interactive testbed
portals, G-monitor portal for Web-based management of Grid applications
execution, and the widely used GridSim toolkit for performance evaluation.
Recently, the Gridbus Project has developed a .NET-based clustering and Grid
Web services framework, called Alchemi, to support the integration of both
Windows and Unix-class resources for Grid computing.
A full status report on various components of the Gridbus Toolkit is
