We describe a new parallel approach to the evaluation of phase space for Monte-Carlo event generation, implemented within the framework of the Whizard package. The program realizes a twofold self-adaptive multi-channel parameterization of phase space and makes use of the standard OpenMP and MPI protocols for parallelization. The modern MPI3 feature of asynchronous communication is an essential ingredient of the computing model. Parallel numerical evaluation applies both to phase-space integration and to event generation, thus covering computing-intensive parts of physics simulation for a realistic collider environment.
