摘　　要：为了提高在线监测系统程序DESCAR模块在燃耗区数目较大时燃耗计算求解的计算效率,本文使用开放式多处理(OpenMP)和信息传递接口(MPI)并行技术,对DESCAR模块进行优化重构,以提高在线监测系统程序的计算效率。验证结果表明,优化重构后的DESCAR模块在保证计算结果正确性的同时,可以有效地提高在线监测系统程序的计算速度,加速效果显著,满足在线监测系统实时性的要求。In order to improve the calculation efficiency of the DESCAR module of the online monitoring system program when the number of depletion zones is large,the DESCAR module is optimized and reconstructed by using the parallel technology of Open Multi-processing(OpenMP)and Message Passing Interface(MPI)to improve the calculation efficiency of the online monitoring system program.The verification results show that the optimized and reconstructed DESCAR module can effectively improve the calculation speed of the online monitoring system program while ensuring the correctness of the calculation results,and the acceleration effect is remarkable,which meets the requirements of the real-time online monitoring system.
