How To Install zfp on CentOS 7
Introduction
In this tutorial we learn how to install zfp on CentOS 7.
What is zfp
This is zfp, an open source C/C++ library for compressed numerical arrays that support high throughput read and write random access. zfp was written by Peter Lindstrom at Lawrence Livermore National Laboratory, and is loosely based on the algorithm described in the following paper Peter Lindstrom “Fixed-Rate Compressed Floating-Point Arrays” IEEE Transactions on Visualization and Computer Graphics, 20(12) doi zfp was originally designed for floating-point data only, but has been extended to also support integer data, and could for instance be used to compress images and quantized volumetric data. To achieve high compression ratios, zfp uses lossy but optionally error-bounded compression. Although bit-for-bit lossless compression of floating-point data is not always possible, zfp is usually accurate to within machine epsilon in near-lossless mode. zfp works best for 2D and 3D arrays that exhibit spatial coherence, such as smooth fields from physics simulations, images, regularly sampled terrain surfaces, etc. Although zfp also provides a 1D array class that can be used for 1D signals such as audio, or even unstructured floating-point streams, the compression scheme has not been well optimized for this use case, and rate and quality may not be competitive with floating-point compressors designed specifically for 1D streams.
We can use yum or dnf to install zfp on CentOS 7. In this tutorial we discuss both methods but you only need to choose one of method to install zfp.
Install zfp on CentOS 7 Using yum
Update yum database with yum using the following command.
sudo yum makecache
After updating yum database, We can install zfp using yum by running the following command:
sudo yum -y install zfp
Install zfp on CentOS 7 Using dnf
If you don’t have dnf installed you can install DNF on CentOS 7 first.
Update yum database with dnf using the following command.
sudo dnf makecache
After updating yum database, We can install zfp using dnf by running the following command:
sudo dnf -y install zfp
How To Uninstall zfp on CentOS 7
To uninstall only the zfp package we can use the following command:
sudo dnf remove zfp
