xpk 1.10.0

xpk helps Cloud developers to orchestrate training jobs on accelerators on GKE.

Overview

XPK (Accelerated Processing Kit, pronounced x-p-k) is a command line interface that simplifies cluster creation and workload execution on Google Kubernetes Engine (GKE). XPK generates preconfigured, training-optimized clusters and allows easy workload scheduling without any Kubernetes expertise.

XPK is recommended for quick creation of GKE clusters for proofs of concepts and testing.

XPK decouples provisioning capacity from running jobs. There are two structures: clusters (provisioned VMs) and workloads (training jobs). Clusters represent the physical resources you have available. Workloads represent training jobs -- at any time some of these will be completed, others will be running and some will be queued, waiting for cluster resources to become available.

The ideal workflow starts by provisioning the clusters for all of the ML hardware you have reserved. Then, without re-provisioning, submit jobs as needed. By eliminating the need for re-provisioning between jobs, using Docker containers with pre-installed dependencies and cross-ahead of time compilation, these queued jobs run with minimal start times. Further, because workloads return the hardware back to the shared pool when they complete, developers can achieve better use of finite hardware resources. And automated tests can run overnight while resources tend to be underutilized.

XPK supports a variety of hardware accelerators.
