초록

본 논문에서는 적은 비용으로 효율적인 패킷 스위칭 상호연결 네트워크를 구성할수 있는 새로운 부류의 MIN (Multistage Interconnection Network)인 SCMIN(ShortCut MIN)을 제안한다. SCMIN은 기존 MIN에서의 스위칭 소자 갯수 보다 매우 적은 수인 2.5N-4 개의 스위칭 소자만을 사용할지라도 FAC(Full Access Capability)를 만족하고, 또한 프로세서-메모리 쌍에 대해 다수개의 중복 경로를 제공할 수 있게 된다. SCMIN은 통신이 빈번하게 발생되는 프로세서 메모리 클리스터에 보다 짧은 경로를 제공하고, 또한 이들에 대한 대체 경로를 제공하여 지역화된 통신 형태의 응용 분야에 적합하도록 설계되었다. 따라서 SCMIN은 공유 메모리 다중 프로세서 시스템에서 지역화된 통신 형태를 갖는 병렬 응용 분야에 적합한 MIN으로 활용될 수 있을 것이다.

In this paper, we propose a new class of MIN (Multistage Interconnection Network) called SCMIN(ShortCut MIN) which can form a cheap and efficient packet switching interconnection network. SCMIN satisfies full access capability(FAC) and has multiple redundant paths between processor-memory pairs even though SCMIN is constructed with 2.5N-4 SEs which is far fewer SEs than that of MINs. SCMIN can be constructed suitable for localized communication by providing the shortcut path and multiple paths inside the processor-memory cluster which has frequent data communications. Therefore, SCMIN can be used as an attractive interconnection network for parallel applications with a localized communication pattern in shared-memory multiprocessor systems.
