LOAD DISTRIBUTION METHOD AND SYSTEM FOR DISTRIBUTED TJREADED TASL OPERATION IN NETWORK INFORMATION PROCESSING APPARATUSES WITH VIRTUAL SHARED MEMORY

In a load distribution method, the load in the entire distributed system is uniformly distributed. In a system in which a plurality of information processing apparatuses (nodes) are connected with a network, the degree of distribution of each distributed task is controlled by expanding or compressing the task. Load distribution is performed by expanding a distributed task operating in a heavily loaded node to a lightly loaded node, and compressing the distributed task from the heavily loaded node and transferring threads within the distributed task. Load distribution servers execute the load distribution method.
