mlockall

In high-performance computing environments or in scenarios where real-time processing is crucial, any delay—even milliseconds—can be costly. Linux provides mechanisms for fine-tuning how memory is managed, and one of these mechanisms involves ensuring that specific processes do not swap their memory to disk. Here's a detailed look at how this can be achieved using mlockall via a Linux bash script. Q: Can you explain what mlockall is and why it might be used in a script? A: mlockall is a system call in Linux that allows a process to lock all of its current and future memory pages so that they cannot be swapped to disk.
