CLOUDS Lab to Release GridSim Toolkit 5.0

The Cloud Computing and Distributed Systems (CLOUDS) Laboratory at
the University of Melbourne, Australia has released the next-version of
Grid simulation software, the GridSim Toolkit 5.0.

This new version of GridSim brings a new package (i.e. gridsim.parallel) that

* A graphical user interface for debugging resource allocation policies.
* Several allocation policies for scheduling parallel jobs on clusters and
and supercomputers. The policies include aggressive backfilling, conservative
backfilling, advance reservation with conservative backfilling, selective
backfilling and agressive backfilling with multiple resource partitions.

* An implementation of the workload model by Lublin and Feitelson for modelling
the workload of clusters and supercomputers.

* A data structure to facilitate the scheduling of jobs and advance reservations.
This data structure is described as an appendix on Marcos Assuncao’s PhD thesis.

* Logging features using Java logging API.

In addition, other improvements have made GridSim more compatible with
Java 5 and 6. Some bugs have been fixed and some changes in SimJava were
required to enable a simulation to be paused and resumed.

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/downloaded by several
academic and commercial organizations around the world including:
University of Southern California (USA), California Institute of Technology (USA),
Argonne National Labs (USA), University of Manchester (UK), CERN,
Universidad de Santiago de Compostela (Spain), Indian Institute of Technology,
Tsinghua University (China), Sun Microsystems, IBM Research, Unisys, HP,
Northrop Grumman Information Technology, British Telecom and EMC Corp.

The contributors to the GridSim software (from early to new versions) are:
* Rajkumar Buyya, CLOUDS Lab @ The University of Melbourne.
* Manzur Murshed, GSCIT @ Monash University, Australia.
* Anthony Sulistio, CLOUDS Lab @ The University of Melbourne.
* Gokul Poduval and Chen-Khong Tham,
Dept. of Electrical & Computer Engineering @ National University of Singapore.
* Marcos Dias de Assuncao, INRIA Lyon @ Ecole Normale Superieure de Lyon
* Uros Cibej and Borut Robic, Faculty of Computer and Information Service,
The University of Ljubljana, Slovenia.
* Agustin Caminero, Department of Computing Systems,
Universidad de Castilla La Mancha (UCLM), Spain.
