  We present BoolSi, an open-source cross-platform command line tool for
distributed simulations of deterministic Boolean networks with synchronous
update. It uses MPI standard to support execution on computational clusters, as
well as parallel processing on a single computer. BoolSi can be used to model
the behavior of complex dynamic networks, such as gene regulatory networks. In
particular, it allows for identification and statistical analysis of network
attractors. We perform a case study of the activity of a cambium cell to
demonstrate the capabilities of the tool.
