CD++: a toolkit to develop DEVS models

Abstract

Summary: the features of a toolkit for modeling and simulation based on the DEVS formalism are presented. The tool is built as a set of independent software pieces running in different platforms. Not only the main characteristics of the environment are presented, but also focus in its use is considered by inclusion of application examples for a variety of problems. Many models can be defined in an automated fashion, simplifying the construction of new models, and easing their verification. The use of this formal approach allowed developing safe and costeffective simulations, reducing significantly development time.

Novel performance optimization of large-scale discrete-event simulation on the Cell Broadband Engine

“…Cell-DEVS [3] describes dynamic systems as cell spaces where each cell is a P-DEVS atomic model. Both P-DEVS and Cell-DEVS are realized in CD++ [4], which has been extended to support parallel simulation on distributed-memory clusters using a flat LP structure [12].…”

“…Each rule has three expressions separated by spaces, defining a postcondition, a delay, and a precondition for the rule. A rule is fired when its precondition is evaluated to true; and the rule's postcondition will define the cell's next state, which is sent to the neighboring cells after a period calculated from the delay expression [4]. A full interpretation of the fire model can be found in [14].…”

“…Cell-DEVS [3] defines n-dimensional cell spaces as discrete-event models where each cell is a basic DEVS model component. Both P-DEVS and Cell-DEVS have been implemented in CD++ [4], which is an object-oriented Modeling and Simulation (M&S) environment programmed in C++.…”

A Framework for Remote Execution and Visualization of Cell-DEVS Models

“…CD++ [5] is a tool built to implement the DEVS and Cell-DEVS theory. The toolkit has been built as a set of independent software pieces, each of them independent of the operating environment chosen.…”

Performance Analysis of an Optimistic Simulator for CD++

“…CD++ [8] is an M&S toolkit that implements P-DEVS and Cell-DEVS formalisms. In [9], a parallel conservative simulation engine, called as PCD++, was incorporated into CD++.…”
