Workspace synchronization waits与同步访问工作空间的进程相关的统计信息。 对象中的每个计数器均包含以下实例: 项说明 平均等待时间(ms)所选类型等待的平均等待时间。 每秒的累积等待时间(ms)所选类型等待的每秒累积等待时间。 正在进行的等待数当前正在等待的以下类型的进程数。 每秒启动的等待数每秒启动的
Contribution description Adds Linux-kernel-like wait queue for mutex-less condition signaling. Motivation Copy-paste from core/include/wait_queue.h: Wait queues enable lock-free, IRQ-safe condition...

Workspace synchronization waits Statistics relevant to processes synchronizing access to workspace. Each counter in the object contains the following instances: Expand table ItemDescription Average wait time (ms) Average time for the selected type of wait. Cumulative wait time (ms) per second Aggregate...
PG_THREAD_WAIT_STATUS allows you to test the block waiting status about the backend thread and auxiliary thread of the current instance.The waiting statuses in the wait_s
使用ZooKeeper的应用程序通常是利用同步原语(synchronization primitives)去实现它们自己的定制化需求,就像上面说的那样。这里,我们将展示如何用ZooKeeper实现锁,以表明它可以实现各种各样的通用同步原语。 最简单的锁实现使用“锁文件”。该锁由znode表示。为了获取锁,客户端尝试创建带有临时标志的指定znode。如果创建成功,...

Note that even in the older xnu version, THREAD_RESTART was still a valid defined value for wait_result_t. In fact, you can see that it is returned in wait_queue_assert_wait64 of osfmk/kern/wait_queue.c when the queue becomes invalid. The difference is that in this older kernel vers...
wait data sync queue Waiting for putting the row-store data pages into the synchronization queue. flush data: [nodename](plevel), [phase] Waiting for sending data to the plevel thread of the node specified by nodename. If phase is included, the possible phase is wait quota, indicating th...
Methods, systems, and mediums are described for scheduling data parallel tasks onto multiple thread execution units of processing system. Embodiments of a lock-free queue structure
