toplev 是 pmu-tools 中的一个工具,在 Intel CPU 的 Linux perf 基础上实现了 TMAM 方法。toplev 可以定位 CPU Bound 代码的瓶颈,不能识别其他(Not bound by CPU)代码的瓶颈。toplev 是一个计数工具,它使用 PMU 来计数事件。toplev 的一个典型使用场景是,用户已经根据一个标>准工具(例如 perf, sysprof, py...
Phasor Measurement Unit (PMU) was first introduced in 1980's by J.S. Thorp and A.G. Phadke at Virginia Tech. First commercial PMU was manufactured by Macrodyne in 1990s and since then many utilities such as New York Power Authority (NYPA), Bonnevilla Power Administration (BPA), Southern ...
