Introduction of migratable task on function-distributed multiprocessor environment

摘要

When a real-time system is implemented on a function-distributed multiprocessor, the method classifies tasks into task class and improves the response of system has been suggested. As a means to increase the system throughput introduction of task class which tasks can migrate between processor has been discussed. This class allocates a task on the processor dynamically and needs new operation to manage. In this study, the concrete operation which needed on introduction of this task class was discussed, and implementation of system to real environment was carried out. Also, the system performance was verified on the side of a management overhead, and a method which improves overhead based on the verified result has been discussed.
