Claim Text:
1. A scheduler causing a specific core in a multi-core processor to execute a process comprising: first detecting, by the specific core, from a group of processes constituting a program to be executed, a group of unset scheduling processes whose group of subsequent processes is common; second detecting, by the specific core, for each of the unset scheduling processes of the detected group of unset scheduling processes and from a group of preceding processes for the unset scheduling processes, a preceding process belonging to a group to which the unset scheduling processes of the detected group of unset scheduling processes belong, the group to which the unset scheduling process belongs being among groups formed by grouping processes that share same or related data to be accessed; allocating, by the specific core, each of the unset scheduling processes of the detected group of unset scheduling processes respectively to a core in the multi-core processor and to which the detected preceding process is allocated; calculating, by the specific core, for each of the unset scheduling processes of the detected group of unset scheduling processes, elapsed time of an execution time period of each of the unset scheduling processes of the detected group of unset scheduling processes from an execution ending time at which the group of preceding processes for the unset scheduling processes of the detected group of unset scheduling processes completely ends; and setting, by the specific core, for each of the allocated unset scheduling processes, an execution starting time of each of the allocated unset scheduling process at an allocation destination core such that an execution of a respective unset scheduling process is to be completed at a most recent calculated elapsed time; wherein the allocating includes allocating an interrupt process consequent to the program to be executed and a second program is allocated, to a core for which no preceding process belonging to the group to which a respective unset scheduling process of the detected group of unset scheduling processes belongs is detected at the second detecting.
