Abstract
A data processing system includes an interrupt controller that counts, as an interrupt processing execution count, executions of interrupt processing by threads executed by data processing devices; and a processor that is configured to select one scheduling method from among a plurality of scheduling methods, based on the interrupt processing execution count.
Claims2
A scheduling method of assigning a plurality of threads to a plurality of data processing devices that include a first data processing device, the scheduling method comprising:
- assigning to a plurality of second data processing devices, first threads that are among the plurality of threads and subjected to interrupt processing at a first frequency;
- and
- assigning second threads that are among the plurality of threads and subjected to interrupt processing at a second frequency that is lower than the first frequency, to data processing devices among the data processing devices and to which the first threads are assigned that belong to a process to which the second threads belong.
