py rapl

py-rapl：一個非常簡單的函式庫，用於透過 powercap/sysfs 介面對 RAPL 計數器進行採樣

介紹

py-rapl是一個非常簡單的函式庫，支援對 RAPL 或運行平均功率限制能量計數器進行取樣，大多數（如果不是全部）現代 Intel CPU 都提供該計數器。

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"))
