Programmatic Cluster Scaling
============================

.. _ref-autoscaler-sdk-request-resources:

ray.autoscaler.sdk.request_resources
------------------------------------

Within a Ray program, you can command the autoscaler to scale the cluster up to a desired size with ``request_resources()`` call. The cluster will immediately attempt to scale to accommodate the requested resources, bypassing normal upscaling speed constraints.
