Multiprocessing is the use of two or more processes that usually execute in parallel on multiple cores. Objects that implement the Parallel interface can take advantage of multicore systems by executing parts or all of their algorithm in parallel. Parallelizable objects can utilize various parallel processing Backends under the hood which are set using the setBackend() method.

Note: Most parallel learners are configured to use a Serial backend by default.

Set Backend#

To set the backend processing engine:

public setBackend(Backend $backend) : void


use Rubix\ML\Backends\Amp;

$estimator->setBackend(new Amp(16));
