Introduction
Analytical Models
This research activity deals with performance evaluation and optimization of computer systems with the help of analytical models. Today, evaluation is an essential part of the planning, development, tuning and comparison of computer systems as well as production systems. Depending on the goal, the hardware structure, the system software or user programs are the central point. Careful modelling is therefore the prerequisite for dependable judgements. Queueing networks or stochastic Petri networks are often used in the modelling of hardware structures and operating system strategies. Precedent graph models are more suitable for modelling (parallel) user programs. The respective models are the basis for analytical investigations. Using these, performance values like response time, utilization, throughput rate or speed-up can be calculated.Projects
