Investigating software design pattern behavior in multiprocessor systems: A case study on observer

With the emergence of multicore processors, parallel software is beginning to be used in the domain of application software in addition to high performance computing software. The use of parallel processing hardware with current software engineering techniques and principles, like object oriented programming, will surely produce new challenges in area and change the way we look at quality criterions. In this work, experiments on bringing a software design pattern to a parallel environment are explained regarding different aspects of parallelization like data consistency, scalability and workload distribution. All the experiments are performed by keeping the parallelization at object level in order to reason about discussions that can be made on object oriented software design for multicore systems. Discussions include adaptation of current software to multicore platforms, important points when designing software for multicore systems and possible research on quality criterions of parallel software. As a result of our initial studies we have seen that it is promising to conduct research on object-level parallelism in multicore systems.
