Abstract
In a distributed-memory multiprocessor system in which a plurality of processors have their respective memories, some of the processors are placed in redundant execution of writing into a virtual storage space. At redundant execution, each processor makes a determination of whether or not it is to perform the writing. As a consequence, only a single processor is allowed to write data into the virtual storage space, which solves the data transfer overhead problem. If a processor that has a memory with an area to be written into performs the writing, then the speed of processing will be further increased.
