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. For starters,
it:
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.

Melbourne.
