The present disclosure provides systems and methods for domain decomposition in parallel numerical computer modelling that remove the need for large-scale synchronization, decouple the regions within a simulation, and reduces wait times, increasing linear scalability and thus suitability for large-scale cloud deployment. Presently disclosed systems and methods include asynchronous message passing which decouples the computational units within the system and introduces an elasticity that allows wait time to be largely eliminated. Applications include domains in which computations are not easily parallelized and/or large-scale numerical simulations used with a large cluster or cloud computing facility.
