Title:
THREAD SYNCHRONIZATION DEVICE, THREAD SYNCHRONIZATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/111611
Kind Code:
A1
Abstract:
Execution speed of a thread is dynamically restored, while effects on the processing precision of a system as a whole is suppressed. This thread synchronization device (10) divides time-sequence data into a plurality of sets and synchronizes N threads (1-1, …, 1-N) for parallel processing. An environmental variable that will result in a trade-off between processing precision and execution speed is set individually for each of the threads (1-1, …, 1-N). An execution speed calculation unit (2) calculates an execution speed for each thread. An environmental variable update unit (3) updates the environmental variable in accordance with the execution speed of the thread.
