mutatisIV / BINGO-Hackaton

Instructions to construct a docker image with a lot of tools for modern observational cosmology and a set of lectures.

BINGO Hackaton

This is intended to be a course on cosmological code for modern observational cosmology aiming graduate students.

You will fild here hands on lessons and detailed instruction to build your own system with docker.

This system provides:

• camb
• class
• CosmoMC
• MontePython
• Cosmosis
• Cobaya
• CosmoHammer

You should start learning here. You may run the python part of the course in binder:

I am in a hurry:

git clone https://github.com/lbarosi/BINGO-Hackaton.git
cd BINGO-Hackaton
make build
make run  

Open your browser and navigate to http://localhost:8888

WARNING: building the docker image the first time may take almost 1 hour!

Starting to Work

Cloning the repo

git clone https://github.com/lbarosi/BINGO-Hackaton.git
cd BINGO-Hackaton
git checkout

Making the container

cd bingo-Hackaton
docker build -t lbarosi/cosmos:complete -f Dockerfile-cosmos .

or

make build

real 45m22,561ss

Running the container and further installs

docker run --rm --mount type=bind,source=$(SOURCE),target=$(TARGET) $(IMAGE):$(TAG)

or

make run-jupyter TAG=complete

Checking What we have so far

1. Docker IMAGE
2. Linux UBUNTU system
3. Gnu compilers
4. Python3 and Python2 installed
5. Conda manager
6. Jupyter Notebook
