Research on co-simulation task scheduling based on virtualization technology under cloud simulation

By introducing virtualization technology, cloud simulation platform can break tight coupling between soft simulation resources (OS, software, model, etc) and computing resources, shield the heterogeneity of underlying computing hardware, and flexibly divide computing resources, which makes the simulation task scheduling agile, transparent and efficient. Due to the characteristics of co-simulation: consistency and close coupling of time and space, one abstract description model of both co-simulation task and computing resources in cloud simulation is proposed, and then two task scheduling models based on different objectives and constraints are put forward, including models for green energy-saving and minimal time span respectively. Finally, the aforementioned scheduling models applied in one aircraft virtual prototype co-simulation are discussed in detail which proves their advantages, and also future work is presented.
