ASSIGNING SPECULATIVE PROCESSES TO PLURALITY OF CPUS BASED ON CALCULATED MAXIMUM NUMBER OF SPECULATIVE PROCESSES CAPABLE OF BEING ASSIGNED AND OTHER PROCESSES ASSIGNED TO EACH CPU

A scheduling method is executed by a given CPU among multiple CPUs. The scheduling method includes subtracting for each of the CPUs, a number of processes assigned to the CPU from a maximum number of speculative processes that can be assigned to each of the CPUs; summing results yielded at the subtracting to yield a total number of speculative processes; and assigning to the CPUs, speculative processes of a number is less than or equal to the total number of speculative processes.
