ec2-cluster 0.2.0a4

A tool for launching and running commands on a cluster of EC2 instances

ec2-cluster

Simple library and CLI to manage and work with clusters of EC2 instances. Multi-purpose, but created to make distributed deep learning infrastructure easier.

ec2-cluster is designed for simple distributed tasks where Kubernetes is overkill or where fast cluster spin up/down is crucial. Example use cases are running distributed deep learning on an expensive cluster or running distributed load testing from many EC2 instances.

Goals

• Provide the minimal set of features to run distributed deep learning training jobs on EC2 instances.
• Provide libraries, not a framework or platform.
• Make cluster environments reproducible to allow for parallelization of experiments
• Make cluster launches fast
• Be resilient to EC2 capacity limitations
• Encourage ephemeral infrastructure design
• Focus on iterative, not disruptive, improvements on the common methodology of manually launching EC2 instances, ssh-ing to them, configuring environments by hand and running scripts

Overview

ec2-cluster can be consumed in two ways:

• A CLI for launching, describing and deleting clusters.
• A python library for scripting.

This library has three main components:L

• infra: creating cluster infrastructure
• orch: orchestrating simple runtime cluster configuration (e.g. generate a hostfile with runtime IPs)
• control: running commands on the cluster
