java 中的线程优先级的范围是1～10，默认的优先级是5。“高优先级线程”会优先于“低优先级线程”执行。 java 中有两种线程：用户线程和守护线程。可以通过isDaemon()方法来区别它们：如果返回false，则说明该线程是“用户线程”；否则就是“守护线程”。用户线程一般是用户执行用户级任务，而

Delivery Threads (ThreadMode) EventBus可以为您处理线程：事件(events)可以在不同于发布线程(the posting thread)的线程中发布(be posted)。一个常见的用例是处理UI更改。在Android中，UI更改必须在UI(主)线程中完成。另一方面，网络或任何耗时的任务都不能在主线程上运行。EventB

TensorFlow的Session对象是支持多线程的，可以在同一个会话（Session）中创建多个线程，并行执行。在Session中的所有线程都必须能被同步终止，异常必须能被正确捕获并报告，会话终止的时候， 队列必须能被正确地关闭。 TensorFlow提供了两个类来实现对Session中多线程的管理：tf.Coordinator和 tf.
import tensorflow as tfq = tf.FIFOQueue(2, "int32")init = q.enqueue_many(([0, 10],))x = q.dequeue()y = x + 1q_inc = q.enqueue([y])with tf.Session() as sess: init.run() for _ in range(5): v, _ = sess.run([x, q_inc]) print(v)

Python3.2中引入的concurrent非常的好用，只用几行代码就可以编写出线程池/进程池，并且计算型任务效率和mutiprocessing.pool提供的poll和ThreadPoll相比不分伯仲，而且在IO型任务由于引入了Future的概念效率要高数倍。 而threading的话还要自己维护相关的队列防止死锁，代码的可读性也会
