Abstract
A hardware thread causes a SleepID register of a WAKEUP signal generation unit to store a SleepID that identifies the hardware thread when suspending a process due to waiting for a process by another CPU. The WAKEUP signal generation unit causes the WAKEUP data register of the WAKEUP signal generation unit to store a SleepID notified by a node when a process that the hardware thread waits ends. The WAKEUP signal generation unit outputs a WAKEUP signal that cancels the stop of the hardware thread to the hardware thread when the SleepIDs of the SleepID register and the WAKEUP data register agree with each other.
