How To Install libdivide-devel on Fedora 36
Introduction
In this tutorial we learn how to install libdivide-devel on Fedora 36.
What is libdivide-devel
This package contains a header-only C/C++ library for optimizing integer division. Integer division is one of the slowest instructions on most CPUs, e.g. on current x64 CPUs a 64-bit integer division has a latency of up to 90 clock cycles whereas a multiplication has a latency of only 3 clock cycles. libdivide allows you to replace expensive integer divsion instructions by a sequence of shift, add and multiply instructions that will calculate the integer division much faster. On current CPUs you can get a speedup of up to 10x for 64-bit integer division and a speedup of up to to 5x for 32-bit integer division when using libdivide. libdivide also supports SSE2, AVX2 and AVX512 vector division which provides an even larger speedup.
We can use yum or dnf to install libdivide-devel on Fedora 36. In this tutorial we discuss both methods but you only need to choose one of method to install libdivide-devel.
Install libdivide-devel on Fedora 36 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
After updating yum database, We can install libdivide-devel using dnf by running the following command:
sudo dnf -y install libdivide-devel
Install libdivide-devel on Fedora 36 Using yum
Update yum database with yum using the following command.
sudo yum makecache --refresh
After updating yum database, We can install libdivide-devel using yum by running the following command:
sudo yum -y install libdivide-devel
How To Uninstall libdivide-devel on Fedora 36
To uninstall only the libdivide-devel package we can use the following command:
sudo dnf remove libdivide-devel
