Recoverable distributed shared memory system with reduced stable logging

This paper presents a novel logging scheme for recoverable distributed shared memory systems. In the previous schemes, the stable logging is performed whenever a remote data value is accessed. However, in the proposed scheme, the data values are logged on the volatile storage of the writer process and only the access information between the dependent processes is logged stably. Also, to reduce the logging frequency, the access information is collectively logged either at the writer process or at the dependent processes. The performance of the proposed scheme is analyzed through extensive simulation study and the new logging scheme shows superior performance in various system environments.
