PURPOSE: To avoid the concentration of acquisition requests to a single external memory and improve responsibility by providing plural external memories for acquisition of working information in order to disperse the acquisition request.
CONSTITUTION: For a calculation system, plural (d) units of external memories 23W25 for acquisition of working information are connected to a central processor 21 which calculates the input information via an input/output channel 22. The requested working information is dispersed on these external memories for acquisition. Thus the increment of time for acquisition of information which is due to concentration of acquisition requests can be avoided. To disperse the requested working information, the following systems are available, that is, the external memories are changed in the order of issue of acquisition requests of working information; the requests are dispersed every virtual memory space where the requesters have actions; the requests are dispersed every type of working information; and the requests are dispersed every type of processing of the requesters.
