Further developments of a novel, multi-processor approach to MRI simulations, open to the sequence and hardware development community, are presented. The underlying mechanisms provide the most general and yet computationally efficient solution of the Bloch equations by means of variable time-stepping numerical integration. The parallel software scales almost ideally and has been implemented to run on a variety of different hardware and operating system combinations. Symbolic mathematical evaluation provides huge flexibility in sequence design without additional programming. Parallel receive as well as transmit functionality promote the simulation of contemporary and relevant developments in the acquisition as well as excitation theory.
