Overview
This unit will cover the following topics:
(1) The origins and nature of concurrency: inherently concurrent systems and potentially concurrent systems.
(2) Processes: basic concepts, mechanisms for creating concurrent activities.
(3) The need for interprocess communication and synchronisation: shared memory-based communication and synchronisation; critical sections, atomic actions, mutual exclusion, condition synchronisation, semaphores, monitors.
(4) Message passing: asynchronous message passing, synchronous message passing (CSP/Occam model), remote invocation (Ada model).
(5) Problems with concurrent systems: deadlock, livelock, starvation, permanent blocking, liveness and safety.
(6) Implementation of concurrent systems: introduction to operating systems, concurrency and operating systems; overall structure and functions of an operating system.
(7) Process management: process state, process descriptors, context switching, process scheduling.
Implementation of interprocess communication and synchronisation.
(8) Memory management: Memory hierarchy, process address space, virtual memory, segments, pages, address translation.
(9) File management: directory structures, file system interface, file system implementation considerations.
(10) Device management: device interfaces and data rates, polling, interrupts and exceptions, interrupt handling, priorities, vectors, memory-mapped I/O.
