Distributed Shared Repository: A Unified Approach to Distribution and Persistency
نویسندگان
چکیده
This paper proposes an information management system providing distribution and persistency. By separating context from virtual address space, our system has a uni ed approach for both distribution and persistency. The former is achieved by moving contexts between sites and the latter by moving contexts between virtual address space and persistent storage. Contexts include any information including data, program, and even the state of execution of a program. Contexts are stored persistently in a logical space termed the distributed shared repository (DSR for short). This paper proposes a programming model for DSR. Using the model, persistency, ne-grain mobility of information, and the passing of various distributed parameters can be obtained. The implementation and experimental performance of the system are also presented.

Distributed Shared Memory (DSM) is an architectural approach that allows processors to support a single shared address space that is implemented with physically distributed memory. The consistency model of a DSM system specifies the ordering constraints on concurrent memory accesses by multiple processors. Lots of Consistency Model are defined by a wide variety of source including architecture ...
