초록

본 논문에서는 KDSM(KAIST Distributed Shared Memory) 시스템의 설계 및 구현에 관해서 설명한다. KDSM은 Linux 2.2.13 상에서 실행되는 사용자 수준 라이브러리로 구현되었고, TCP/IP를 기반 통신 구조로 사용한다. KDSM은 페이지 기반 무효화 프로토콜(page-based invalidation protocol)과 다중 쓰기 프로토콜(multiple writer protocol)을 기반으로 하고, HLRC(Home-barred Lazy Release Consistency) 메모리 일관성 모델을 사용한다. KDSM의 성능을 측정하기 위해서 4개의 과학계산용 응용 프로그램을 실행하여 JIAJIA와 성능 비교를 하였다. 그 결과, 2개의 응용은 같은 결과를 냈고, 나머지 2개는 KDSM의 성능이 우수하였다.

In this paper, we give a detailed description of KDSM(KAIST Distributed Shared Memory) system. KDSM is implemented as a user-level library running on Linux 2.2.13, and TCP/IP is used for communication. KDSM uses page-based invalidation protocol, multiple-writer protocol, and supports HLRC(Home-based Lazy Release Consistency) memory consistency model. To evaluate performance of KDSM, we executed 4 scientific applications and compared the result to JLAJLA. The results showed that performance of KDSM almost equal to JIAJIA for 2 applications and performance of KDSM is better than JIAJIA for 2 applications.
