py rapl

py-rapl：一个非常简单的库，用于通过 powercap/sysfs 接口对 RAPL 计数器进行采样

介绍

py-rapl是一个非常简单的库，支持对 RAPL 或运行平均功率限制能量计数器进行采样，大多数（如果不是全部）现代 Intel CPU 都提供该计数器。

用法

 import rapl

s1 = rapl.RAPLMonitor.sample()
# Some work that you want to measure.
s2 = rapl.RAPLMonitor.sample()

# Take the difference of the samples
diff = s2 - s1

# Print the difference in microjoules
print(diff.energy("package-0", "core", rapl.UJOULES))

# Print the average power
print(diff.average_power("package-0", "core"))
