Dear All,

Last month, we released our Gridbus - Grid Service Broker, which
supports various low-level grid software including globus 4.0. Pls see
attached message for further details.

Cheers

The Gridbus Project to Release Grid Service Broker (2.4 version) Software
16 November 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 v2.4 supports/uses the following middleware:
Globus 2.4.x,Globus 3.2, Globus 4.0
Alchemi 1.0
Condor 6.6.9,
OpenPBS 2.3,
SGE,
NWS 2.8,
SRB(Storage Resource Broker) 3.x,
XGrid Technical Preview 2 & 1.0 (experimental),
Unicore 4.1.0 (experimental)

The Gridbus Broker v2.4 can utilise a resource via SSH for submitting and
executing
grid jobs on:
OpenPBS 2.3,
SGE,
Fork (on Unix-class systems)


What's New:
----------
- Support for Globus 4.0 job submission services using WS_GRAM
- Improved stability for all middleware
- Improved persistence in order to support a wider range of databases. Also,
introduced in-process and dynamic database creation via HSQLDB.
- New event-based Round-Robin scheduler that provides a simple scheduling
algorithm.
- Various bug fixes
