This paper presents the design of a copying garbage collector for persistent distributed shared objects in a loosely coupled network with weakly consistent dis- tributed shared memory (DSM). The main goal of the design for this garbage collec- tor is to minimize the communication overhead due to collection between nodes of the system, and to avoid any interference with the DSM memory consistency protocol. Our design is based on the observation that, in a weakly consistent DSM system, the memory consis- tency requirements of the garbage collector are less strict than those of the applications. Thus, the garbage collector reclaims objects independently of other copies of the same objects without interfering with the DSM consistency protocol. Furthermore, our design does not require reliable communication sup- port, and is capable of reclaiming distributed cycles of dead objects.
