Title: Innovations by Satoki Shibayama
Introduction
Satoki Shibayama is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of computer systems and processing methods. With a total of 2 patents, his work focuses on enhancing CPU efficiency and job control systems.
Latest Patents
Shibayama's latest patents include a CPU usage time counting method and a job control system utilizing this CPU usage time. The CPU usage time counting method involves counting the actual usage time of each CPU in a distributed processing environment. This method first counts the CPU usage time for each job, then measures the processing wait time during memory access. By subtracting the processing wait time from the CPU usage time, the corrected CPU usage time is established, which is then used for job control and user charging.
Another significant patent is the parallel process execution method for multiprocessor computers. This method allocates CPU time to parallel processes at desired ratios. It sets a time allocation ratio to determine the execution time for a parallel program. The method ensures that parallel processes are assigned to multiple processors and executed simultaneously. When the elapsed time reaches the set allocation ratio, the execution of these processes is halted across all processors.
