How To Install sleef on Fedora 34

sleef is Vectorized math library Vectorized math library

Introduction

In this tutorial we learn how to install sleef on Fedora 34.

What is `sleef`

SLEEF stands for SIMD Library for Evaluating Elementary Functions. It implements vectorized versions of all C99 real floating point math functions. It can utilize SIMD instructions that are available on modern processors. SLEEF is designed to efficiently perform computation with SIMD instructions by reducing the use of conditional branches and scatter/gather memory access. The library contains implementations of all C99 real FP math functions in double precision and single precision. Different accuracy of the results can be chosen for a subset of the elementary functions; for this subset there are versions with up to 1 ULP error (which is the maximum error, not the average) and even faster versions with a few ULPs of error. For non-finite inputs and outputs, the functions return correct results as specified in the C99 standard. sleef 3.5.1 3.fc34 x86_64 852 k sleef-3.5.1-3.fc34.src.rpm fedora Vectorized math library https Boost SLEEF stands for SIMD Library for Evaluating Elementary Functions.

We can use yum or dnf to install sleef on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install sleef.

Install sleef on Fedora 34 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

After updating yum database, We can install sleef using dnf by running the following command:

sudo dnf -y install sleef

Install sleef on Fedora 34 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

After updating yum database, We can install sleef using yum by running the following command:

sudo yum -y install sleef

How To Uninstall sleef on Fedora 34

To uninstall only the sleef package we can use the following command:

sudo dnf remove sleef
