ATLAS (Automatically Tuned Linear Algebra Software)

ATLAS is an amazing open-source software that's totally free! It's all about providing a collection of super-optimized Linear Algebra kernels, and it's designed for different cache-based architectures. You’ll find that it’s implemented in both C and Fortran, making it pretty versatile for developers.

What Makes ATLAS Special?

This software gives you Fortran77 and ANSI C interfaces, covering the entire BLAS API. Plus, it even touches on some parts of the LAPACK (Linear Algebra Package) API. So if you're into linear algebra stuff, this tool is definitely worth checking out!

The Goal of ATLAS

The main goal behind ATLAS is to help users apply some nifty techniques for better performance across different systems. It includes efficient implementations of the BLAS (Basic Linear Algebra Subprograms) and lots of routines from LAPACK too.

Getting Started with ATLAS

If you want to try it out, you can only download ATLAS as a universal sources archive (tarball). This means you get to optimize and compile it specifically for your hardware setup—whether that’s 32-bit or 64-bit. It's all up to you!

How to Download

You need to grab the latest stable release from its official website. Once downloaded, save the package on your computer and extract the contents using your favorite archive manager.

Installation Steps

Next up, open a terminal emulator. In the Linux Terminal, use the ‘cd’ command to go to where you extracted those files. Create a new folder called ‘MyObj’ with the ‘mkdir’ command, then type in ‘./../configure’ to set everything up. You’ll find various executables and a Makefile waiting for you in that directory!
