mendevi.g5kpower.g5kpower

mendevi.g5kpower.g5kpower(hostname: str, start: Real, duration: Real, *, login: str | None = None, password: str | None = None) → dict[str][source]

Do a request to get the grid5000 consumption.

Parameters

hostnamestr: The hostname containing the node name and the site. It can be get with platform.node().
startfloat: The starting timestamp, it can be get by time.time().
durationfloat: The job duration in seconds.
login, pswstr: Username an password for grid5000 api.

Returns

Consumption: dict[str]

‘dt’: The time difference between 2 consecutive power measurements (in s).
‘energy’: The total energy consumption (in J).
‘power’: The average power, energy divided by the duration (in w).
‘powers’: The power measured between 2 consecutive points (in w).

Raises

ValueError: If the request failed.

Examples

>>> import platform, time
>>> from mendevi.g5kpower import g5kpower
>>> g5kpower(platform.node(), time.time()-10.0, 10.0)
>>>

Notes

Tested with oarsub -I -p paradoxe -t deploy -t monitor=’wattmetre_power_watt’.
Power and time measurements are differental to increase the compressibility of the database containing this result.
Energy is estimated from the trapezoidal integral of instantaneous powers.
