Dear Colleagues:

On behalf of the Gridbus Project at the University of Melbourne,
Australia, I am pleased to inform you that we have released the
next-version of Grid simulation software, the GridSim 3.0 toolkit
with support for advanced reservation of resources.

The new version of GridSim has been substantially improved. They include:
- adds new functionalities, especially regarding to advanced reservation
mechanisms. GridSim has the framework / infrastructure to handle
advanced reservation functionalities, such as:
* create a new reservation
* commit a reservation
* cancel an existing reservation
* modify an existing reservation
* query the status of an existing reservation


- make GridResource and GridInformationService class to be more extensible.

- modify the overall GridSim architecture to incorporate advanced
reservation functionalities. In addition, this new architecture is more
extensible and easier to create your own GridResource and/or
GridInformationService entity.

- add different ways to initialize GridSim, see GridSim.init() methods
for more details.

- fix minor bugs and encoding problem on example source code.

All components developed as part of the GridSim Toolkit are released as
"open source" under the GPL license to encourage innovation and pass
full freedom to our users.

The early version of our GridSim toolkit has been used/dowloaded by
several academic and commercial organizations around the world
including: California Institute of Technology, Argonne National Labs,
University of Illinois at Urbana-Champaign, Manchester University, CERN,
Univ. of Ljubljana, National University of Singapore, Indian Institute
of Technology, Tsinghua University, Sun Microsystems, IBM, Unisys,
HP, British Telecom, and EMC Corporation.

The GridSim software has been used for modeling and simulating many
interesting systems. For example, Unisys's usage in data centre modeling
and Univ. of Ljubljana's extension of GridSim to support DataGrid.
Our own usages include simulating economic Grid scheduler in a
competitive economy model, economic based cluster scheduler, and
cooperative grid federation.

The contributors to the GridSim software (early/new version) are:
GridSim base platform also broker:
* Rajkumar Buyya, GRIDS Lab @ University of Melbourne
* Manzur Murshed, GSCIT @ Monash University
* Anthony Sulistio, GRIDS Lab @ The U. of Melbourne.

GridSim visual modeller by:
* Anthony Sulistio, GRIDS Lab @ The U. of Melbourne.
* Chee Shin Yeo, GRIDS Lab @ The U. of Melbourne.
