srl-roles: code for deploying experiments

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

On all nodes:

1. Setup passwordless SSH and sudo
2. Install Docker

1. Start an experiment master:

   ./emaster.sh

2. Pick an experiment and configure it:

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

3. Run the job:

   [EXPERIMENT_MASTER] ansible-playbook experiment.yml

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.

• 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

See the docs directory for information on setting up experiments and for additional developer resources.
