Abstract

PURPOSE:To evenly disperse the I/O load of a secondary memory file in an I/O system by calculating and registering the busy rate of each auxiliary memory at each fixed interval time. CONSTITUTION:The real memory address of a page to be paged out is supplied to a page-out channel program production means 8. Thus an auxiliary memory that is not kept under a busy state (under I/O processing and had the minimum busy rate at the previous interval time is obtained out of a table 2 via an optimum secondary file name acquiring means 5 among those auxiliary memories containing the secondary files. Then the pages are allocated. As a result, the I/O loads of the secondary memory files are evenly dispersed so that the high- speed and low-speed auxiliary memories if mixed up can be effectively used respectively.
