An information processing method includes: accepting a request for execution of a new task; identifying at least either one of a processing time required for the new task and a bus bandwidth required for processing the new task; making at least either one of comparisons between a total required processing time, which is a sum of processing times required for the new task and a reserved task reserved on a scheduler for indicating a procedure pertaining to a plurality of tasks, and a processing time available in an apparatus that executes those tasks, and between a total required bus bandwidth, which is a sum of bus bandwidths required for processing the reserved task and the new task, and a bus bandwidth available in the apparatus that executes those tasks; determining whether the new task is executable or not, based on the result of comparison(s); making a reservation for the new task on the scheduler if the new task is determined to be executable; and processing the tasks including the new task which is determined to be executable based on the scheduler, wherein the determining of whether the new task is executable or not includes acquiring priority information on the new task, and whether the new task is executable or not is determined based on the priority information acquired.
