Announcement: A major new version of QPME <http://qpme.sourceforge.net/>
(Queueing Petri net Modeling Environment), version 2.0, was released
today and is now available under the terms of the Eclipse Public License
(EPL) v1.0 <http://www.eclipse.org/legal/epl-v10.html>."
Project Website: http://qpme.sourceforge.net/
QPME <http://qpme.sourceforge.net/> (Queueing Petri net Modeling
Environment) is a tool for stochastic modeling and analysis based on the
Queueing Petri Net (QPN) <http://ls4-www.cs.tu-dortmund.de/QPN/>
modeling formalism. Queueing Petri Nets are a combination of
conventional queueing networks and stochastic Petri nets providing
increased expressiveness and thus making it possible to model systems at
a higher degree of accuracy. The development of the tool started in 2003
at the Technische Universität Darmstadt and was continued at the
University of Cambridge from 2006 to 2008. Since 2008, QPME is being
developed and maintained by the Descartes Research Group
<http://www.descartes-research.net/> at Karlsruhe Institute of
Technology (KIT). The first version was released in January 2007 and
since then the tool has been distributed to more than 120 universities,
companies and research institutes worldwide.
QPME is made of two components: QPE (QPN Editor) and SimQPN (Simulator
for QPNs). QPE provides a user-friendly graphical tool for modeling
using QPNs based on the Eclipse/GEF framework
<http://www.eclipse.org/gef/>. SimQPN provides an
efficient discrete-event simulation engine for QPNs that makes it
possible to analyze models of realistically-sized systems. QPME runs on
a wide range of platforms including Windows, Linux, Mac OS and Solaris
among others.
The *new features* introduced in Version 2.0 include:
* Advanced query engine for processing and visualization of the
results from model analysis.
* Centralized management of queue specifications.
* Support for having multiple queueing places that share the same
underlying physical queue.
* Significant improvements in the performance and scalability of the
simulation engine (SimQPN).
* Support for simulating hierarchical QPNs using SimQPN.
* Support for defining probes that specify metrics of interest for
which statistics should be collected during a simulation.
* Automatic detection of infinitely growing queues (model instability).
* Support for empirical and deterministic distributions.
* A number of features improving user friendliness (e.g., simulation
progress bar and "stop simulation" button).
* New simulation configuration parameters "bucketSize" and
"maxBuckets" to customize histogram generation.
* Ported to the latest Eclipse version 3.6.
* Various bug fixes and optimizations.
