  • Patent number: 10831547
    Abstract: An accelerator control apparatus includes: a task storage part which holds an executable task(s); a data scheduler which selects a task needing a relatively small input/output data amount on a memory included in an accelerator when the task is executed by the accelerator from the executable task(s) and instructs the accelerator to prepare for data I/O on the memory for the selected task; and a task scheduler which instructs the accelerator to execute the selected task and adds a task that becomes executable upon completion of the selected task to the task storage part, wherein the data scheduler continues, depending on a use status of the memory, selection of a next task from the executable task(s) held in the task storage part and preparation of data I/O for the next task selected.
