PROBLEM TO BE SOLVED: To provide an information processor, an information processing system, a control method of the information processor and a control program of the information processor capable of optimizing the split ratio of a sector in a shared cache memory for plural jobs.SOLUTION: The information processor includes: a shared cache memory having a sector function which is split according to the degree of reuse of data; and a control unit that changes the split ratio of the sector in the shared cache memory. The control unit calculates the split ratio of the sector based on the size of the data to be accessed by the first and second jobs, the data access amount having access frequency, and the capacity of the shared cache memory responding to an instruction by the program of the second job during executing the first job and the second job to change the split ratio to the calculated split ratio of the sector. |
