PURPOSE:To improve a processing capability by accumulating the number of input/output (I/O) processing for each task and allocating an optimum processor when the task concerned is activated next time according to the total number of data I/O processing and its number of times. CONSTITUTION:A counter 9 is connected to the BUS3 of a CPU1, which is a multi-counter for the product of the total number of tasks and systems. A counter 49 is also connected to the local BUS43 of an I/O channel 41. The I/O device which is used the most by the counter concerned is determined to the counter 9. The counter 49 counts the number of tasks for the I/O device concerned, and the number of tasks for the I/O channel which includes the counter having the maximum value is sent to the counter 9 to add the number of tasks for determining the I/O channel to the task concerned. |
