PROBLEM TO BE SOLVED: To surely and effectively perform distributed processing among a plurality of information processors connected through a network. SOLUTION: Each of information processors 1, 2, 3 and 4 comprises a main processor 21 and sub-processors 23. When a sub-processor program according to a user's operation is executed in a sub-processor, the information processor 1 determines whether a necessary number of empty sub-processors are present within the own device or not, and ensures, in a case that they are present, the necessary number of sub-processors within the own device. When the necessary number of empty sub-processors are not present within the own device, the information processor 1 successively requests the other information processors 2, 3 and 4 to ensure sub-processors. When the necessary number of sub-processors cannot be ensured only by the empty processors within the whole network, a sub-processor which is executing a sub-processor program with low priority is ensured for executing the sub-processor program according to the user's operation.
