Introduction
In this tutorial we learn how to install blosc on CentOS 8.
What is blosc
Blosc is a compression library designed to transmit data to the processor cache faster than the traditional non-compressed memory fetch. Compression ratios are not very high, but the decompression is very fast. Blosc is meant not only to reduce the size of large datasets on-disk or in-memory, but also to accelerate memory-bound computations.
We can use yum or dnf to install blosc on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install blosc.
Install blosc on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
