摘要

PROBLEM TO BE SOLVED: To suppress increase of traffic on a shared bus used for management of cache consistency and also to suppress delay of memory access about a distributed shared memory type computer having a constitution including plural nodes connected together via the mutual connection means. SOLUTION: Each of nodes has plural cache consistency management means and a consistency management selection means which selects a cache consistency management means according to the type of memory access.
