numactl

In modern computing, optimizing performance is not just about upgrading hardware; it's also about intelligently using available resources. One such technique involves binding specific processes to designated CPU cores to enhance performance, particularly on multi-core systems. The Linux utility numactl effectively achieves this by manipulating NUMA (Non-Uniform Memory Access) policies. Here, we'll explore how to use numactl to bind a script to specific CPU cores. Q1: What is numactl? numactl is a command-line utility in Linux that allows you to run a program with a specified NUMA scheduling or memory placement policy.
