DESIGN AND IMPLEMENTATION OF MOONY - A FAULT-TOLERANT DISTRIBUTED SHARED-MEMORY SYSTEM

Abstract

Shared memory is a natural high level programming paradigm in particular in distributed computing environments. In this paper, we describe the design and implementation of a fault-tolerant distributed shared memory system (FTDSM) called Moony,which provides shaved memory abstraction and guarantees continuous services even in the presence of site crashes. Moony is implemented at application level with a set of daemon sewers and provides services to users via Moony library function calls. The first prototype is portable to all Unix machines that support BSD socket and System V IPC. The preliminary results demonstrate that FTDSM is viable and, that Moony is portable over a wide variety of distributed environments.
