摘　　要：在一体化仿真建模工具的性能优化时,内存分配优化方面提出内存池式分配方式,该分配方式特采用全局内存池基础实现并加上并行线程内存管理的方法来较好地匹配仿真工具的系统多临时对象和多动态分配内存的应用特点,性能测试表明,该内存池具有良好的空间特性和效率,比传统的操作系统直接分配内存节省约50.7%的分配时间。When optimizing the performance of the integrated simulation modeling tool,the memory pool allocation method is put forward in the aspect of memory allocation optimization.This allocation method is implemented on the basis of global memory pool and the method of parallel thread memory management is used to better match the application characteristics of multi-temporary objects and multi-dynamic memory allocation of the simulation tool.The performance test shows that the memory pool has good space characteristics and efficiency.It saves about 50.7%of the allocation time than the traditional operating system to allocate memory directly.
