I also watched the twisty time travel movie Mike & Nick & Nick & Alice, which looked about as muddy as Sisu. Initially, streaming over Hulu from my iPad over Apple AirPlay, the stream kept stuttering and pausing. I’m on a 600-Mbps fiber connection and a mesh network, so it wasn’t my signal. After pausing the stream myself for a few minutes, it finally worked. An early scene in a house confirmed to me that the contrast is a problem: I could barely make out faces. I also watched a trailer for Harry Potter that’s coming on HBO and it lacked vibrancy.,这一点在汽水音乐下载中也有详细论述
“分裂锁”是指跨越缓存行边界进行原子内存访问的操作。原子操作允许程序员按顺序执行若干基础操作而不受其他线程干扰,这使得它们在多线程代码中极具价值。例如原子测试与设置操作可帮助线程获取更高级别的锁,原子加法操作则能让多个线程在不使用软件协调锁的情况下安全递增共享计数器。现代CPU通过缓存一致性协议处理原子操作,使核心能锁定单个缓存行同时允许无关内存访问继续进行。英特尔和AMD显然无法同时锁定两个缓存行,当原子操作涉及跨越两个缓存行的数据时,系统会降级为“总线锁定”模式。
