# This is a basic workflow to help you get started with Actions

name: Build

# Controls when the action will run. Triggers the workflow on push or pull request
# events but only for the master branch
on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
  # This workflow contains a single job called "build"
  build:
    # The type of runner that the job will run on
    runs-on: ubuntu-latest

    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:
    # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it

    # We don't want to build openmpi each time this workflow is
    # run. Setup caching of OpenMPI after it is built and installed.
    # See "Caching dependencies to speed up workflows" on the GH
    # actions docs.
