Kaira is as an open-source development environment for MPI (Message Passing Interface) applications. We try to provide an unified environment for activities for development: prototyping, programming, testing, debugging, profiling, performance prediction, and verification.

The main idea is to use visual models (inspired by Coloured Petri Nets). This model is designed to catch parallel aspects and communication inside of the developed application. We do not want to program applications completely in a visual way, so our models can be enriched by any sequential C++ code. With such model, a user can generate MPI applications, run simulations, or start a state-space analysis.
