摘要： A single virtual space management scheme suitable for a distributed system. The single virtual space for arranging programs and/or data among a plurality of computers forming the distributed system are divided into a plurality of regions called memory chapters, and a part of the single virtual space to be managed independently by each computer is requested from each computer in units of these memory chapters. Then, a server allocates one of the memory chapters to each computer in response to each request from each computer, while managing allocations of the memory chapters to the plurality of computers so as not to allocate each one of the memory chapters to more than one computers. Each memory chapter allocated to each computer is independently managed by further dividing each memory chapter into a plurality of sub-regions called memory sections, and carrying out an access protection in units of these memory sections at each computer.

摘要： According to an aspect of the present invention, in a virtual space unit area, a message is distributed among computers using a physical topology based on a physical network. This avoids delaying operations in a computer which are related to those in another computer on a virtual space and taking a roundabout route on the physical network for distribution. On the other hand, outside the virtual space unit area, a message is distributed among computers using a virtual topology based on a virtual space. Consequently, the computers forming the physical topology can be limited to those present in the virtual space unit area. It is thus possible to reduce the amount of communication required to measure physical network distances.

摘要翻译： 根据本发明的一个方面，在虚拟空间单元区域中，使用基于物理网络的物理拓扑在计算机之间分发消息。 这避免了计算机中与虚拟空间上的另一台计算机相关的延迟操作，并在物理网络上采取迂回路由进行分发。 另一方面，在虚拟空间单元区域之外，使用基于虚拟空间的虚拟拓扑在计算机之间分发消息。 因此，形成物理拓扑的计算机可以限于存在于虚拟空间单元区域中的计算机。 因此可以减少测量物理网络距离所需的通信量。

摘要： A write control method of exclusively controlling write requests from a plurality of user terminals to an identical structured document is disclosed. The identical structured document includes a plurality of elements each containing document content. A monitor field is set in units of the elements within the identical structured document. Upon accepting one write request from one user terminal, it is determined if the one write request is directed to the document content under monitoring by referral to the monitor field. Then, the one write request is handled to reject overwriting of the document content despite the one write request if the document content has been rewritten by another write request from another user terminal in advance.
