摘　　要：针对分布仿真系统中的内存分配问题,提出了一种基于VMIC的内存分配算法,利用向量和映射相结合的方式对VMIC板卡的内存空间进行动态分配和释放。试验表明,该算法能够准确地为仿真数据分配和释放空间,处理内存分配和释放过程中出现的异常,且能够及时合并空闲空间以减少内存碎片,从而满足分布仿真系统对大量数据的存取需求。According to the memory allocation problem in distributed simulation system , a dynamic memory allocation algo-rithm is proposed based on VMIC , which allocates and frees the memory space dynamically by vector and map .The test indicates that the algorithm is able to allocate memory and free memory for simulation data accurately , deal with the exceptions during memory allocation and release , and combine free memory together timely to reduce memory fragments as well , thus satisfying the access re-quirements of huge data in distributed simulation system .
