wait_barrierT_wait_barrierWaitBarrierWaitBarrierwait_barrier — Wait on the release of a barrier synchronization object.

wait_barrier( : : BarrierHandle : )

wait_barrierwait_barrierWaitBarrierWaitBarrierWaitBarrierwait_barrier blocks the thread at a barrier object given by BarrierHandleBarrierHandleBarrierHandleBarrierHandlebarrierHandlebarrier_handle until a specified number of threads have called the same barrier object. This number is specified by parameter TeamSizeTeamSizeTeamSizeTeamSizeteamSizeteam_size during the creation of the barrier object by create_barriercreate_barrierCreateBarrierCreateBarrierCreateBarriercreate_barrier.

Multithreading type: independent (runs in parallel even with exclusive operators).
多线程作用域:全局(可以从任何线程调用)。
未经并行化处理。
