Concurrency allows theimprovement of software performance by exploiting available processor cores. However, possibleperformance gained by concurrency can be limited by software bottlenecks or inherently sequentialparts of the application. Performance prediction methods help software architects to nd softwarebottlenecks in multiprocessing environments during the design phase. Unfortunately, in highlyconcurrent systems, current prediction methods result in errors up to several orders of magnitude.They neglect important in uences of the operating system schedulers and middleware leading toerroneous predictions. Therefore, this thesis addresses the challenge of performance predictionin symmetric multiprocessing environments. It proposes a performance modelling framework foroperating system schedulers such as implemented in Windows or Linux.
