About the course: This course teaches various aspects of computer-aided modelling for performance evaluation of (stochastic) dynamic systems. The emphasis is on stochastic modelling of computer systems and communication networks; however other dynamic systems such as manufacturing systems will also be considered. The central concept of the course will be that a model, as well as being an abstract representation of a system, is a tool which we can exploit to derive information about the system. The more detail we invest in the model, the more sophisticated the information we can extract from it. As the course progresses the models will become increasingly detailed; the corresponding solution techniques will similarly become more complex, relying on increasing levels of computer assistance and visualisation.
Lecture notes: The course lecture notes are by Jane Hillston.
Software and models
Over the course we will encounter a number of different approaches to constructing performance models and software tools to support their use. Example models will be made available here and students are encouraged to use the examples to gain a deeper understanding of both the modelling styles and the software tools.
There is a short movie here which may help you with installing the PEPA Plug-in for Eclipse. You will find the plug-in and further instructions at http://www.dcs.ed.ac.uk/pepa/tools/plugin/download.html.
Coursework:
PEPA
There will be two pieces of assessed coursework.
Practical 1 (2011) (Issued on 7th October, due 3rd November 2011, returned 11th November 2011)
Individual written feedback has been given and a specimen solution was handed out in lecture.
Those who were not in the lecture to collect their marked work should collect it from the ITO.
The second practical is now available:
Practical 2 (2011) (Issued on 8th November, due on 8th December 2011.
For the second question you may find it helpful to download the fragment of a PEPA model in the file practical2-ACPI.pepa.
There are no tutorials for this course but individual assistance is available: mail me and make an appointment.
Individual feedback and a specimen solution will be provided.
There is no textbook for this course but extensive notes will be given.
If you want further information on the topics covered you may consider the books in the course booklist.
