How To Install libsys-cpuaffinity-perl on Debian 9
Introduction
In this tutorial we learn how to install libsys-cpuaffinity-perl on Debian 9.
What is libsys-cpuaffinity-perl
libsys-cpuaffinity-perl is:
The details of getting and setting process CPU affinities varies greatly from system to system. Even among the different flavors of Unix there is very little in the way of a common interface to CPU affinities. The existing tools and libraries for setting CPU affinities are not very standardized, so that a technique for setting CPU affinities on one system may not work on another system with the same architecture.
Sys::CpuAffinity seeks to do one thing and do it well: manipulate CPU affinities through a common interface on as many systems as possible, by any means necessary.
The module is composed of several subroutines, each one implementing a different technique to perform a CPU affinity operation. A technique might try to import a Perl module, run an external program that might be installed on your system, or invoke some C code to access your system libraries. Usually, a technique is applicable to only a single or small group of operating systems, and on any particular system, the vast majority of techniques would fail. Regardless of your particular system and configuration, it is hoped that at least one of the techniques will work and you will be able to get and set the CPU affinities of your processes.
