The use of parallelism enhances the performance of a software system. However, its excessive use can degrade the system performance. In this report we propose a parallelism viewpoint to optimize the use of parallelism by eliminating unnecessarily used parallelism in legacy systems. The parallelism viewpoint describes parallelism of the system in order to analyze multiple overheads associated wi...

[ABSTRACT] Logic programs provide many opportunities for parallel execution. Among different forms of parallelism found in logic programs, AND-parallelism and OR-parallelism have shown to be most effective in speeding up the execution of logic programs. Research in the exploitation of AND-parallelism, OR-parallelism alone and combined AND/OR-parallelism has led to the proposals and implementati...
