👩‍🚀 📡 🔬 Continuous Integration for Scientific Applications

This repository contains a brief example of Continuous integration for scientific applications, using miniconda and Python3.

Overview

Continuous Integration (CI) helps to automate the testing and delivery of scientific software tools. A CI is just a workflow that runs automatically 🤖 as a result of a certain action taken in the source code (e.g. a push, pull-request, etc.).

This repository contains 3 different configuration files for Github Actions, Travis and Gitlab CI. These configuration files encode the actions to perform with the code on a given architecture, like installing the library from scratch in a Ubuntu machine.

🛠️ Setting up a CI workflow

GitHub actions

The Github actions configuration can be found at Python actions file. There is comprehensive documentation of what Github actions are and how to use them.

Travis CI

The Travis configuration file contains the configuration to call a CI workflow using Travis. See Travis tutorial.

GitLab CI ******* The `GitLabCI configuration file <.gitlab-ci.yml>`_ contains the configuration to call aCI** workflow using the Gitlab CI. A comprehensive documentation is available for the GitLab CI tool.

Azure pipelines

If you want to use Azure pipelines, have a look at Tania Allard's great tutorial.

🚀 Running on your own infrascture

Sometimes you want to have more control over the hardware infrascture, compilers, etc. when performing continuous integration. GitHub Actions and GitLab CI/CD allow you to set up your infrascture. The following links contains a guide to help you run a CI workflow on your own infrascture:

• GitLab CI/CD self-hosted runner
• GitHub Actions self-hosted runnner

🎮 Running the package examples

This package contains a toy example to estimate the value of π using the Monte Carlo method. To run the Monte Carlo calculator, you will need to have python install. We recommend you create a conda virtual environment by following the instructions below,

1. Get a copy of miniconda

2. Create a new environment by running the following command:

   conda create --name ci_for_science python=3.7 -y -q

3. Activate the environment:

   conda activate ci_for_science

Now to install this package,

4. Fork and clone this repo

5. install cython:

   pip install cython

6. install the library from the repo root folder:

   cd ci_for_science && pip install -e .

7. run the command line interface like:

compute_pi -n 1000

The previous command will estimate π using 1000 random points.
