Problems solved by technology

[0003] In the traditional implementation method, high-performance computers are usually used to design serial algorithms to realize the operation and scheduling of each software system. In this method, higher requirements are put forward for the operation speed and reliability of the computer located at the central node. At the same time, in order to achieve This requirement requires high cost and difficult design, which is not conducive to later optimization

Because different specifications of hardware are often used in flight simulation systems, such as onboard computers (flight control computer, flight management computer), etc., the resulting heterogeneity is not conducive to the design of serial computing systems. Long, so the serial system is not conducive to the upgrade and expansion of the partial system

In the traditional serial computing system, the failure of a single system will cause abnormal operation of the whole system, resulting in fault propagation, and it is not easy to design fault shielding, fault tolerance and redundancy
