The Stochastic Pi Machine (SPiM) is a programming language for designing and simulating computer models of biological processes. The language is based on a mathematical formalism known as the pi-calculus, and the simulation algorithm is based on standard kinetic theory of physical chemistry. The language features a simple graphical notation for modelling a range of biological systems, and can be used to model large systems incrementally, by directly composing simpler models of subsystems

    • Luca Cardelli worked on the formal specification of SPiM, the design of the SPiM language, and on extensive testing and debugging.
    • Rich Williams developed the Network 3D software for visualising simulations in 3D.
    • Stefan Leye assisted with debugging the SPiM scheduling algorithm.
    • James Margetson and Luca Cardelli developed the SPiM GUI.
    • Pascal Zimmer assisted with debugging the OCaml bytecode distribution.
    • The BioSpi project was the main inspiration for SPiM, and many of the SPiM chemical examples are adaptations of earlier BioSpi models.
    • The core SPiM language was developed in F#.
