초록

가격대비 성능이 좋은 저가의 상업용 SMP가 클러스터 시스템의 노드로 많이 사용되고 있다. 본 논문에서는 이러한 SMP 클러스터 상에서 KDSM을 확장해 소프트웨어 분산공유메모리를 구현하고 성능을 평가하였다. 본 논문의 SDSM 시스템은 HLRC 메모리 모델을 제공한다. 또한 같은 SMP 노드내에서 실행되는 프로세스 간에는 메모리 공유를 통해 페이지 획득 및 메시지 전달을 줄여 성능을 향상시켰다. 100Mbps Fast Ethernet으로 연결된 8노드의 2-way 펜티엄-III SMP 클러스터 상에서 구현되었고 통신계층은 TCP/IP를 사용한다. 8개의 응용프로그램을 실행시켜 얻은 성능 평가에서는 기존의 단일프로세스 프로토콜과 비교해 최대 33%의 성능 향상과 13%-52%의 페이지 획득 감소가 나타났다.

Low-cost commodity SMP(Symmetric Multiprocessor) is widely used as a node of cluster system. In this paper, we implement and evaluate the performance of SDSM system for SMP clusters. Our SDSM system provides HLRC(Home-based Lazy Release Consistency) memory consistency model. Our protocol utilize shared memory within same SMP node, so that page fetch and message passing through network can be reduced. It is implemented on 8 node of 2-way Pentium-III SMP interconnected with 100Mbps Fast Ethernet, and uses TCP/IP for transport/network layer protocol. The experiment with eight applications shows that our SMP protocol achieves maximum 33% speedup improvement and 13%-52% reduction of page fetch compared with uniprocessor protocol.
