echo

Lost? Try running:

./runecho

When prompted,

• you are not on the BRC
• you do not have a jobs.json
• you want to run a script: scripts/single
• yes it should have made and returned the corrent jobs.json file
• run one job for job id = 0

Setup

Please install a virtual env manager, Anaconda is suggested with Python 3. Create a new environment and set up there!

> conda create -n echo_env python=3.6
> source activate echo_env
> pip install --user --requirement requirements.txt
> ./runecho

(in progress) A Dockerfile is also supplied. With the current Dockerfile, you can run jupyter notebook. Please edit it to fit your usage.

> docker build . -t ECHO
> docker run -it -p 8888:8888 ECHO /bin/bash -c "jupyter notebook --notebook-dir=/opt/notebooks --ip='*' --port=8888 --no-browser --allow-root"

Go to localhost:8888 and copy and paste the token over.

Don't forget to shutdown your containers.

> docker ps -a 
> docker rm [NAME]

Here's a useful command to rm all containers that are Exited (usually because of an error...), if you, like me are bad with Docker: docker rm $(docker ps -a | grep Exited | awk '{print $1}')

Terminology

protocol - the information protocol (i.e. gradient_passing,loss_passing,shared_preamble,private_preamble)

models - the model used to learn with (classic, neural, poly)

mod_order - QPSK,8PSK,QAM16 for 2, 3, or 4 bits per symbol

experiment - protocol + mod_order + agent model(s) Examples: experiments/gradient_passing/QPSK_neural_and_classic/ or experiments/shared_preamble/QPSK_neural_vs_clone/

trial - an instantiation of a single experiment via sampling and generating new seeds

job - same as trial but agnostic to the experiment because you can have trials of multiple experiments in one jobs.json file

Code Overview

./experiments/[protocol]/model_params.libsonnet stores the default model parameters for running an experiment under that protocol

./experiments/create_experiment.py is used to create an experiment with default settings or command-line specified settings. (See examples of usage in ./scripts/single and ./scripts/singlecustom.)

./experiments/make_jobs.py is used to create a jobs.json file containing the parameters to run multiple trials (sampling or generating seeds) for a single experiment. If you supply a file with multiple experiments (one per line), a single jobs.json will be made containing jobs for all of the experiments listed. (See examples of usage in ./scripts/single, ./scripts/singlecustom, ./utils/preprocess_experiments.py.)

./utils/preprocess_experiments.py creates and makes jobs for ALL of the default experiments. Or for a specific protocol. (See examples of usage in ./scripts/singleprotocol and ./scripts/all.)

./run_experiment.py is used to run experiments from a jobs.json file.

./plot_experiment.py is used to plot the results of a single job output.

Useful commands

./utils/clean : cleans out results, experiments and temporary files.

./utils/clrbrc : cleans out outputs from running on brc

./scripts/single : see the file. creates 1 experiment using default settings, makes the jobs, and then runs the first job

./scripts/singlecustom : see the file. creates 1 experiment using custom params in the custom_params folder, makes the jobs, and then runs the first job

./scripts/singleprotocol: see the file, creates the default experiments for a single protocol, makes jobs into a single jobs.json file, runs the first job.

./scripts/all: see the file, creates the default experiments for all protocols, makes jobs into a single jobs.json file, runs the first job.

./runecho: command-line helper for running experiments.

Running on BRC

./runecho: Use this tool to help you. It knows what to do. ./utils/clrbrc: Use this tool to clean up after you've finished up running to clean up intermediate files

Useful commands:

• squeue -u caryntran: Jobs on the queue / being run
• scancel [job-id]: Cancel a job
• sinfo -p savio2: See nodes available and being used
• wwall -j [job-id]: See the utilization of the nodes

Prerequisites

1. Make GCloud Account
2. Install cloud sdk, docker
3. Make a project + enable billing
4. Make a bucket
5. Enable APIs: AI Platform ("Cloud Machine Learning Engine"), Compute Engine, and Google Container Registry API

Setup

Set these environment variables to make your life easy. Replace bracketed values with UNIQUE identifiers. These must correspond to the project_id and bucket_name you created on GCloud console.

export PROJECT_ID=[torch-echo]
export BUCKET_NAME=[sahai_echo]

These can be whatever you want:

export BASE_NAME=[echo_tuning]
export IMAGE_REPO_NAME=$BASE_NAME_pytorch_container
export IMAGE_TAG=$BASE_NAME_pytorch

export NOW=$(date +%Y%m%d_%H%M%S)
export JOB_NAME=$BASE_NAME_container_job_${NOW}
export MODEL_DIR=$BASE_NAME_pytorch_model_${NOW}
export JOB_DIR=gs://$BUCKET_NAME/$MODEL_DIR
export REGION=us-west1
export IMAGE_URI=gcr.io/$PROJECT_ID/$IMAGE_REPO_NAME:$IMAGE_TAG

Prepare the container

Build the Dockerfile Test it locally Push it onto Google Cloud

docker build -f Dockerfile -t $IMAGE_URI ./
docker run $IMAGE_URI --total-batches 10 --log-interval 2 
docker push $IMAGE_URI

Submit job

Run on Google Cloud

gcloud beta ai-platform jobs submit training $JOB_NAME \
  --job-dir=$JOB_DIR \
  --region=$REGION \
  --master-image-uri $IMAGE_URI \
  --config=config.yaml \
  --scale-tier BASIC
