Gridbus Project To Release GridSim Toolkit 3.0

The Gridbus Project at the University of Melbourne, Australia has 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, Manchester University, CERN, University of Ljubljana, National University of Singapore, Indian Institute of Technology, Tsinghua University, Sun Microsystems, IBM, Unisys, HP, British Telecom and EMC Corp.

The GridSim software has been used for modeling and simulating many interesting systems. For example, Unisys's usage in data center modeling and University 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.
