EMU: Software Services Development Group emulation project

Project Description

Emu is a simulation software designed to show the architecture and operational mechanics of supercomputers used in Oak Ridge National Laboratory.

How to install and setup Frontend and Backend

  1. Download local copy of source code from https://github.com/olcf/ssd_emu using git clone [email protected]:olcf/ssd_emu.git

Backend

  1. Install ruby with rbenv (Fedora)
    • Install rbenv dependency from Fedora rbenv
    • When installing rbenv from fedora official repository, it won't have 3.2.2 which is why we need to re install rbenv manually.
    • Clone ruby-build by git clone https://github.com/rbenv/ruby-build.git
    • Run following command to install ruby-build
    •   cd ruby-build
  chmod u+x ./install.sh
  ./install.sh
  rbenv install 3.2.2
    • Check the version by running rbenv --version
  2. Setup postgresql
    • Install postgres following instruction at fedora-postgresql docs.
    • Install postgresql-devel package by sudo dnf install postgresql-devel (bundle installer won't work without this package)
    • Make sure you provide all the privileges to current user.
  3. Install ruby dependencies using Bundler
    • cd ssd_emu/rails-server
    • rbenv local 3.2.2
    • bundle install
  4. Install and setup docker if you haven't already
    • Install docker following the setup from Docker Docs
    • Create a user by sudo usermod -aG docker $USER
    • newgrp docker
    • Restart docker to apply changes systemctl restart docker
  5. Setup databases
    • Create database using bin/rails db:create
    • Load database seed using bin/rails db:seed
    • Migrate database bin/rails db:migrate
  6. Launch server
    • bin/rails server

Frontend

  1. Install Node.js and node modules required for this project.
    • Install node js using sudo dnf install nodejs for Fedora (Our project uses node with version of v22.11.0)
    • Confirm Node.js installation by node --version which outputs something like v22.11.0.
  2. Install node modules
    • cd ssd_emu/vue-client
    • Install node modules by running npm i.
  3. Run the project
