未检测到任何事件! Ubuntu 22.04 上的 PAPI 7.1.0

问题描述 投票:0回答:1

我正在尝试使用 PAPI 检查大学作业的处理器事件,但使用时没有显示任何 PAPI 预设事件

papi_avail -a

在我安装了 libopenmpi-dev、papi-tools 和 PAPI 7.1.0 后,

papi_avail -a
的输出是:

Available PAPI preset and user defined events plus hardware information.

No events detected!  Check papi_component_avail to find out why.

在此之后我使用了

papi_component_avail
,输出是:

                                Native: 0, Preset: 0, Counters: 0

那么我需要做什么才能让 papi 检测到处理器事件呢? 感谢您的帮助!

你尝试过吗

papi_native_avail
?这应该显示 165 个不同的本机事件。
papi_avail
仅显示预设事件(可能是原生事件或源自原生事件)。

您的 PAPI 版本似乎在系统上配置了 0 个预设事件。但是,您可以根据本机事件计算性能指标(例如 FLOP 或 L1/L2/L3 数据缓存未命中)。
