With the expanding simulation scale of complex engineering systems, requirements of modelingand simulation accuracy continue to increase, which highly demand on simulation systems and simulationrun support environment. In such a case,this paper first proposed the architecture of high efficiency simula-tion cloud,which is supported by high performance simulation computer,and propose the key technologiesof high efficiency simulation cloud. Secondly, the paper is in depth research on key technologies, such asmulti-tenant for simulation system, high performance RTI for complex system, and fault tolerance in theprocess of the simulation run which run on the high efficiency simulation cloud environment. Finally, thispaper gives the corresponding research and solutions. By this method not only can we solve problems thatalready exist, such as collaborative interoperability, simulation model reuse issue in the process oflarge-scale,complex systems engineering modeling and simulation,but also ensure reliability and efficiencywhen the simulation runs.
