A design and modeling methodology for performance evaluation in real-time, distributed software systems

The authors present a new design methodology which constructs software systems to meet performance objectives. The goal is to integrate performance engineering into software engineering. The process begins early in the software lifecycle and uses performance models to identify satisfactory designs and to eliminate those that are likely to have unacceptable performance, before developers invest significant time in implementation. The process includes the performance analysis and special parallel software design phases (i.e., restructuring, partitioning, and allocation) as an integral part of the software design process
