devstone
DEVStone is a benchmark utility designed to compare performance of Discrete-Event Simulators.
Definition of DEVStone can be found in these publications:
The DEVStone benchmark has 4 kind of models to be studied.
- LI: these models have a low level of interconnections, i.e. one input and one output port, for each coupled model. The input port is connected to each component but only one component produces an output through the output port.
- HI: these models have a high level of input couplings. Each atomic component a connects its output port to the input port of the a+1th component.
- HO: these are models with high level of coupling and numerous outputs. HO models have two inputs and two outputs at each level where each one of the atomic components triggers the entire first set of (width-1) atomic models.
- HOmod: these are models with high level of coupling and numerous outputs. HOmod have a second set of (width-1) models where each one of the atomic components triggers the entire first set of (width-1) atomic models.
Our goals
- Keep track of the performance characteristics of our simulator, Cadmium.
- Easily compare performance characteristics against other well-known simulators.
