Live target experimentation

from lisa.tests.scheduler.eas_behaviour import EnergyModelWakeMigration

We want to create a TestBundle from a live target, so we can use the from_target alternative constructor:

bundle = EnergyModelWakeMigration.from_target(target)

We now have a Target instance. We're free to play around with its data, more specifically to execute some tests related to this data:





In [6]:



    


print(bundle.test_slack())



    


















    






PASSED: emwm_2 delayed activations=1.2 %, emwm_0 delayed activations=1.2 %, emwm_1 delayed activations=1.2 %, emwm_3 delayed activations=1.2 %










    






lisa/remove_testenv/lisa/perf_analysis.py:133: FutureWarning: read_table is deprecated, use read_csv instead.
  'Slack', 'CRun', 'CPeriod', 'WKPLatency'

Whenever possible, we want to expose test margins to the end user. Here, we can change the failure threshold, and for the sake of demonstration we'll set it way too low (and expect a failure)





In [7]:



    


print(bundle.test_slack(negative_slack_allowed_pct=1))



    


















    






FAILED: emwm_2 delayed activations=1.2 %, emwm_0 delayed activations=1.2 %, emwm_1 delayed activations=1.2 %, emwm_3 delayed activations=1.2 %

This test also produces a plot, let's run it and have a look





In [8]:



    


print(bundle.test_task_placement())



    


















    






PASSED: estimated energy=11747.642996651268 bogo-joules, energy threshold=12697.384476751002 bogo-joules

bundle.trace.df_all_events()



    











In [11]:



    


import os
from IPython.display import Image

image_path = os.path.join(bundle.res_dir, "expected_placement.png")
Image(image_path)

Offline replaying

Say someone executed some tests, and ran into some issues. They can create an archive of the results directory and send it your way, and you'll be able to reload it automagically. This also works if you are working on the test code itself, and don't want to re-execute the workload every single time you change the code.





In [13]:



    


# Let's just reuse what was generated in the previous run
archive_dir = bundle.res_dir



    











In [14]:



    


reloaded_bundle = EnergyModelWakeMigration.from_dir(archive_dir)



    











In [15]:



    


# Just to prove we're not cheating!
reloaded_bundle == bundle



    


















    
Out[15]:








False

print(reloaded_bundle.test_task_placement())
