Gridbus Project To Release GridSim Toolkit 3.1

The Gridbus Project at the University of Melbourne, Australia has released
the next-version of Grid simulation software, the GridSim Toolkit 3.1
toolkit.

The new version of GridSim has been substantially improved. They include:

* incorporates a network extension into GridSim.

Now, resources and other entities can be linked in a network topology.
Network elements like routers and links can be extended for more
functionality. The schedulers being used can be modified to support other
scheduling paradigms like EDF, Delay Jitter regulator etc. In addition,
data sent over the network is automatically packetised depending on the
Maximum Transmission Unit (MTU) of a link. This work was done in
collaboration with Gokul Poduval and Chen-Khong Tham from Computer
Communication Networks (CCN) Lab, National University of Singapore (NUS).

* incorporates a background traffic functionality based on a probabilistic
distribution. This is useful for simulating over a public network
where the network is congested.

* incorporates a functionality that reads workload traces taken from
supercomputers for simulating a realistic grid environment.

* adds ant build file to compile GridSim source files.

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.
