Chronomodel can be very demanding on system resources depending on your models. If you create hundreds of objets and launch calculations with millions of iterations, your Random Access Memory will have to be large enough. Your CPU speed controls the calculation time but won't prevent Chronomodel from running correctly.
We don't provide a "minimal" system requirement since simple models will run on almost all configurations.
The application can be built for Mac OS X (10.7 and more), Windows (XP, Vista, 7, 8) and Linux (tested on Ubuntu).
