Abstract : This paper describes the implementation of the page management in Mome, a user-level distributed shared memory (DSM). Mome provides a shared segment space to parallel programs running on distributed memory computers or clusters. Individual processes can request for mappings between their local address space and Mome segments. The DSM handles the consistency of mapped memory regions at the page-level. A node can freely select the consistency model which is applied to its own view of a page among two models: the classical strong consistency model and a simple and very basic weak model. Under the weak model, each process of the parallel application must send a consistency request to the DSM each time its view of the shared data needs to integrate modifications from other nodes. Mome targets the execution of programs from the high performance community using an SPMD computation model and the coupling of these simulation codes using an MIMD model.
