基于共享内存加速逆设计进程间通信

Based on the inverse design experimental platform of micro-nano photonic devices, the time-consuming analysis of parameter transfer between the optimization algorithm and the electromagnetic field solver is carried out, and the inter-process "mixture" communication method based on shared memory is designed. Compared with the HDF5 file method before optimization, the "mixture" communication method reduces the parameter transfer time, and the parameter transfer time in this optimization mode remains stable when multiple simulation tasks are started at the same time. This optimization method can reduce the total time consumption of single-task simulation by 19.48%, and reduce the time consumption by 33.435%, 61.849%, and 45.744% when the number of tasks is started at the same time when the number of tasks is 2, 3, and 4 respectively.
