Purpose: In this tutorial you will learn how to download and quick compile exciting.

---

1. Installation

First, you should choose the directory where you want to unpack the current release, exciting nitrogen. All examples in this tutorial assume that the source code of exciting is unpacked to /home/tutorials. From now on the symbol $ will indicate the shell prompt.

$ mkdir /home/tutorials 
$ cd /home/tutorials

Download the current release, exciting nitrogen here, and unpack it.

$ tar xvf exciting.nitrogen.tar.gz

Before proceeding further, be sure that relevant environment variables are already defined as specified in How to set environment variables for tutorials scripts. If you choose a different location than /home/tutorials, replace /home/tutorials in your ~/.bashrc file with an appropriate path as indicated in How to set environment variables for tutorials scripts.

Then, move inside the exciting directory and compile the code!

$ cd exciting
$ make

The compilation script allows you to choose a compiler and other preferences. For the purpose of using exciting within this and the other tutorials, choose 9 (ifort) and no k-point parallelization support. Pay attention that the (yes/No) choice implies typing a full word and not just the first letter.

perl ./setup.pl
