抄録

Fluid scheduling is an optimal real-time scheduling applicable to multiprocessor systems and is a scheduling model so that every real-time task is executed at a constant speed from release time to deadline. It is necessary for fluid scheduling to control the execution speed of each task. But, since the execution speed of the task is invariable in a conventional general purpose processor. Therefore, fluid scheduling is conventionally achieved by repeatedly executing and stopping tasks. However, this method incurs significant overheads due to frequent task switching. On the other hand, fluid scheduling without overhead by using an IPC control scheme has been proposed. The IPC control scheme controls the execution speed of each thread in an SMT processor. We propose a new IPC control scheme to extract thread-level parallelism and improve throughput effectively, also improving the schedulability of the fluid schedule. The evaluation results show that the proposed method improved the total throughput of the fluid schedule.
