Distributing storage sharing management method

The present invention relates to the system structure of the computer, distributed computer system, parallel processing and computer operation system and specially relates to distributing storage administration of multiple computers system working on MIMD means. Basing on the hardware of the parallel computer system formed by bus bridging, the present invention adopts the new storage administration called memory shared window which is different to both overall situation shared memory and the ordinary DSM storage administration. The coupling degree of multi-computer system can be regulated through the method by setting alpha and beta parameters to improve the entirety performance of the system.
