srl-roles: code for deploying experiments

These are all the systems that the SRL uses in our experiments.

Install

On all nodes:

Setup passwordless SSH and sudo
Install Docker

Quickstart

Start an experiment master:
```
./emaster.sh
```

Pick an experiment and configure it:

[EXPERIMENT_MASTER] cd roles/ceph/test
[EXPERIMENT_MASTER] cp hosts.template hosts

Run the job:

[EXPERIMENT_MASTER] ansible-playbook experiment.yml

Description

This repository has the infrastructure (code, scripts, etc.) for running experiments and graphing results. It deploys, measures, and tears down different systems. Experiments are standalone; they require no extra software or setup.

Motivation

Reproducibility: exchanging code and starting the systems for another person
Tuning and Benchmarking: running jobs overnight and fully utilizing the cluster
Performance Bug Fixes: automatically test multiple code revisions
Isolation: system libraries do not interfere with each other
