Description

The course will cover the UNIX/Linux environment and shell programming. It will also cover computer operating systems and examine the interaction of concurrent processes using C code developed on a Linux system. In particular, the course will focus on the interaction of concurrent processes: means of realising concurrency, and the use of modern interaction primitives, e.g. semaphores, message passing.

Learning Outcomes

1. Work in a UNIX environment and write shell scripts and C programs.
2. Develop code to implement key real-time optimisation techniques.
3. Apply the principles associated with process management and inter-process communications.
4. Demonstrate an understanding of the hardware architecture of modern computer platforms.
