toplev can generate collection scripts with --gen-script which can be run on other systems without pmu-tools (but with working Linux perf). The output can be imported with --import / --topology / --cpuinfo. Note the generation and input command line options need to match. It may also b...

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...
You can set the PATH to include the repository to run the tools from other directories: export PATH=/path/to/pmu-tools:$PATH What tool to use for what? You want to: understand CPU bottlenecks on the high-level: use toplev. display toplev output graphically: use tl-server or toplev --...

I tried the toplev from pmu-tools on the system and I get similar values where backend bound dominates. For frontend bound and bad speculation the formulas has 2 in both numerator and denominator. Any specific reason? As both of these get cancelled out. For MemoryLatency and MemoryR...
