How to Install Spack on Arch Linux

Spack is an open-source package manager designed for high-performance computing (HPC). It simplifies the installation and management of scientific software on HPC systems. In this tutorial, we will show you how to install Spack on Arch Linux.

Prerequisites

Before you start, make sure you have the following requirements:

  • A running installation of Arch Linux
  • A non-root user with sudo privileges
  • Basic knowledge of the Linux command line

Step 1: Update system packages
