lenskit.logging.resource

Measure resource consumption.

Functions

cur_memory()	Get the current memory use for this process
max_memory()	Get the maximum memory use for this process
reset_linux_hwm()

Classes

ResourceMeasurement(wall_time, perf_time, ...)

Single measurement of resources.

class lenskit.logging.resource.ResourceMeasurement(wall_time, perf_time, user_time, system_time, max_rss=None, max_gpu=None)

Bases: object

Single measurement of resources. Two measurements can be subtracted to compute the time resources consumed in an interval (memory resources are left unchanged).

Stability:

Internal (see Stability Levels).

Parameters:

• wall_time (float)

• perf_time (float)

• user_time (float)

• system_time (float)

• max_rss (int | None)

• max_gpu (int | None)

max_rss: int | None = None

Maximum RSS usage (in bytes).

classmethod current()

Get the current resource measurements.

property cpu_time: float

Total CPU time (user + system).

lenskit.logging.resource.max_memory()

Get the maximum memory use for this process

lenskit.logging.resource.cur_memory()

Get the current memory use for this process
