The goal Teaching of the basic concepts of computer performance analysis and its application areas. Explanation of simplified models of computer system components (processors, memory, disks). Providing students with the ability to model and analyze computer systems and networks using stochastic methods and the mean value analysis (MVA) applied to open and closed queuing networks.
The outcome Students will be able to: select the appropriate modeling technique, depending on the characteristics of the computer component or system, set up an abstract model, specify the assumptions and approximations for the specific model, calculate performance indicators based on a set of given parameters, critically discuss the obtained numerical performance indicators, and interpret the results.
