WebDefault schedule • Note that the default schedule for loops with no schedule clause is implementation defined. • Doesn’t have to be STATIC. • In practice, in all implementations I know of, it is. • Nevertheless you should not rely on this! • Also note that SCHEDULE(STATIC) does not completely specify the distribution of loop iterations. Web在第二种情况下，瓶颈是对drand48()的调用，隐藏在对real_rand()的调用中的某处，以及求和。drand48使用在所有线程之间共享的全局状态。在单线程应用程序中，状态通常保存在L1数据缓存中，因此drand48速度非常快。在您的示例中，当一个线程更新状态时，此更改将传播到其他核心并使其缓存无效。
