Memory Management in Linux

This work describes the memory manager subsystem of the linux kernel. The first part gives a brief account of operating systems architecture and memory management theory - of virtual memory management, page tables, page replacement algorithms and kernel allocators in particular. The second part discusses the actual implementation of these principles in a modern kernel - in linux. Finally, a series of tests stressing the memory subsystem is conducted to determine the memory manager's real behaviour. Limitations of the current linux kernel memory management and some of their proposed solutions are also discussed
