pylops.utils.scalability_test

pylops.utils.scalability_test(Op, x, workers=[1, 2, 4], forward=True)

Scalability test.

Small auxiliary routine to test the performance of operators using multiprocessing. This helps identifying the maximum number of workers beyond which no performance gain is observed.

Parameters

Oppylops.LinearOperator

Operator to test. It must allow for multiprocessing.

xnumpy.ndarray, optional

Input vector.

workerslist, optional

Number of workers to test out.

forwardbool, optional

Apply forward (True) or adjoint (False)

Returns

compute_timeslist

Compute times as function of workers

speeduplist

Speedup as function of workers
