PROBLEM TO BE SOLVED: To provide means for assuring a performance as a system in cloud computing.SOLUTION: A program is clock-driven by means of a Timer interrupt, Timer Signal(POSIX/UNIX/Linux), a Timer Event (Windows), or the like that periodically drives the program. When the program is driven by a timer, a determined process is executed and afterward it is inactivated until the program is driven by the timer. Therefore, an execution step number per hour becomes the same in both of a high speed machine and a low speed machine. Accordingly, a performance is the same not depending on the hardware. |
