Description

Data call optimization method and system for simulation platform

Technical Field

The present application relates to the field of data calling, and in particular to a data calling optimization method and system for a simulation platform.

Background technique

The simulation platform generally contains several subsystems, and the intermediate data in the simulation process can be stored in the storage space of any subsystem. Before a simulation calculation of the system starts (generally referring to the start of solving a certain equation), the required data needs to be called from the storage space to the cache space required by the main computing module. Since the amount of data required for solving is large and the cache space of the main computing module is relatively limited, the order in which the data is called and how to open up or release the cache space of the main computing module are the data call optimization techniques of the simulation system.

Under the existing technical solution, the order of data calling is usually determined according to the calculation time sequence in the main calculation module. That is, the data used by the equation first is called out from the storage space of the subsystem and temporarily stored in the cache space required by the main calculation module. After the data is used, the corresponding cache space is released. Although the order of calling data is relatively clear, each call operation consumes additional system time, which increases the total time of solving the equation and reduces the efficiency of the simulation.
