ABSTRACT:
A scheme for realizing a high speed data transfer between memory spaces shared among computers in a distributed computer system, without requiring a complicated and inefficient communication protocol processing at the computer side. One region which is at least a part of a virtual memory space or a real memory space managed by one computer and another region which is at least a part of a virtual memory space or a real memory space managed by another computer are shared between these two computers, and a dedicated virtual connection is set up between these two shared regions. Then, a data transfer between these two shared regions is carried out by using the dedicated virtual connection. A virtual connection identifier of the dedicated virtual connection is registered into a corresponding page table entry in the page table, so that this virtual connection identifier can be obtained at a time of the data transfer by referring to the page table alone.
