The Gridbus Project to Release Grid Service Broker (2.0 version) Software
10 May 2005
-----------------------------------------------------------------------------

The Grid Service Broker, developed as part of the Gridbus Project at the
University of Melbourne, Australia mediates access to distributed "autonomous"
resources by (a) discovering suitable data sources for a given analysis
scenario, (b) suitable computational resources, (c) optimally mapping analysis
jobs to resources, (d) deploying and monitoring job execution on selected
resources, (e) accessing data from local or remote data source during job
execution and (f) collating and presenting results. The broker provides (a)
a declarative and dynamic parametric programming model and (b) a rich set of
Java APIs for creating grid applications. It also allows programmers to create a
user-level scheduler plugins that can replace default Computational and Data
Grid scheduling algorithms that support service price-based resource allocation.

The Gridbus broker v2.0 supports/uses the following middleware:
Globus 2.4.x,Globus 3.2,
Alchemi 0.8.0
Unicore 4.1.0
Condor 6.6.9,
OpenPBS 2.3,
NWS 2.8,
SRB(Storage Resource Broker) 3.x.

What's New:
----------
- New broker persistence model extensible to use storage systems such as
databases, file system, etc.
- Failure management support via the persistence model
- Support for data catalogs such as the SRB MCAT (Storage Resource Broker
Metadata Catalog),
enabling access of data objects stored on SRB server systems.
- Flexible XML-based resource description
- Support for Forking jobs on the local machine, Unicore, Condor,
PBS (experimental)
- Improved support for Globus 2.4.x, Globus 3.2, Alchemi 0.8.0.
- Support for queueing systems such as PBS through Globus.
- Support for retrieval of proxies from MyProxy servers.
- Performance enhancements and bug fixes
- JSR-168 Compliant Portlet-based front-end tools for launching, and monitoring
grid applications.
- Expanded user and programmer's manual
