Language and platform

Language Python 3.10.12
Platform : Lenovo T570
CPU : Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz (x86_64)
RAM : 2133 MHz - 8GB

Measure justification

Using VJoule and 1000000 runs on two samples (a good one and a bad one), here are the results :

Processing rule EC2 - language python
RUNNING vjoule
TESTING good CASE

time    1s697ms87µs
PDU     0.00 J
CPU     13.48 J
RAM     0.96 J
GPU     0.24 J
----------------------
RUNNING vjoule
TESTING bad CASE

time    1s557ms165µs
PDU     0.00 J
CPU     12.59 J
RAM     0.74 J
GPU     0.15 J
----------------------

Validation

The measurement performed invalidates the rule for the pyhton language.

The percentage of certainty of this validation 70%, the results seem to vary from one run to the other, and in more than 50% of the runs the bad case performs better (less execution time, less CPU power, less RAM power, less GPU power) :
