Project Description
Java Modelling Tools (JMT) is a suite of applications released under GPL license. The project aims at offering a comprehensive framework for performance evaluation, system modeling with analytical and simulation techniques, capacity planning and workload characterization studies.
The current stable version of the suite includes six Java applications: JSIMgraph, JSIMwiz, JMVA, JABA, JWAT and JMCH.
Latest Version
Download: JMT 1.5.0 (Released 02-Nov-2026; What’s new).
