Abstract
An information processing apparatus having at least one processor and a main storage, accessed by the processor, and capable of providing a plurality of logical information processing apparatus by logically partitioning the information processing apparatus. The information processing apparatus includes a main storage partitioned into a plurality of memory areas, each of the memory areas corresponding to one of the plurality of logical information processing apparatus. The information processing apparatus further includes a first storage unit for storing identification information for each of the memory areas identifying the logical information processing apparatus allocated to each memory and a read unit for reading the identification information from the first storage unit when the main storage is to be accessed by one of the plurality of logical information processing apparatus. Each of the plurality of logical information processing apparatus possesses a unique identification information. The information processing apparatus further includes a comparison unit for comparing the identification information read by the read unit with the identification information of the one logical…
