| 摘要: |
| SVM系统或称DSM系统是在基于分布存储器的多处理机上,实现物理上分布但逻辑上共享的存储系统.它集共享存储器易于编程和分布存储器可扩充性好于一体,为MPP计算机的使用带来了方便.本文首先介绍了SVM系统的数据一致性问题及其解决办法,然后提出了一种新的固定分布管理算法NFDMA,并对此算法作了分析,最后与李凯的固定分布管理算法作了比较. |

| Abstract: |
| A shared virtual memory(SVM) system can provide a virtual address space shared by all processors in a loosely-coupled distributed memory multicomputer. It combines the salability of network based architectures with the convenience of shared memory programming. This paper, firstly discusses some issues for maintaining data consistency in SVM system, then proposes a new fixed distributed manager algorithm. Finally, this paper gives a analysis of NFDMA and compares to Li s scheme. |
