A Common Framework for Inter-Process Communication on a Cluster

摘要

Many implementations of distributed shared memories (DSMs) have been developed to date. All of the implementations have taken into consideration, the performance issues of DSM systems more than other issues like the portability of programs and API. DSM systems have APIs that fit a specific system and require a programmer's adaptation to that specific API. A migration between systems might require a significant revision of a program. Moreover, programmers who write programs for SMPs need to rewrite large portions of their programs in order to scale up their programs from SMP to a cluster of computers. We are presenting a concept for a distributed system, in which an API for any IPC mechanism will be identical, or very close to the SMP's conventional API. This concept can accustom programmers to a distributed system with ease, as well as improving the migration of existing SMP programs to distributed systems.
