Abstract
A permission setting register stores therein information indicating whether or not access is to be permitted to each node, per segment of a shared memory. When an abnormality occurs in a node, a permission canceling unit sets, for a segment that the abnormal node has been using, information in the permission setting register, the information corresponding to the abnormal node, to not permit access. When there is an access request from a remote node to a shared memory segment, a checking unit determines, with hardware, whether or not the access is permitted, based on the permission setting register, an access token included in the access request, and a memory token register.
