The basics of OS memory management

In this section, we will go into the fundamentals of memory management in modern OSes. Those already familiar with this topic can skim through this section quickly as a refresher.

Memory is among the most fundamental and critical resources available to a running program (process). Memory management deals with the allocation, use, manipulation, ownership transfer, and eventual release of memory used by a process. Without memory management, executing a program is not possible. Memory management is performed by a combination of components, such as the kernel, program instructions, memory allocators, and garbage collectors, but the exact mechanism varies across programming languages and OSes.

In this section, we will look at the memory management lifecycle and then learn the details of how memory is laid out for a process by the operating system.

The memory management lifecycle

In this section, we will cover the different activities associated...

Hands-On Concurrency with Rust

Hands-On Concurrency with Rust

Writing safe and correct parallel programs is tough. Reasoning about concurrent memory modification is tough; efficiently exploiting the modern computing environment (with its multi-layered caches and deep execution pipelines) is also tough. Most systems programming languages add a further complication: unsafe memory access. The burden on you, the programmer, lies across two domains: understanding the modern machine and understanding your language's pain-points. Rust, with its safe memory model and strong type system, eases this last burden without sacrificing performance. This book will teach you to reason about program performance on modern machines and build fast, memory-safe, and concurrent software in Rust.
