Concurrency by modularity: design patterns, a case in point

General purpose object-oriented programs typically aren’t embarrassingly parallel. For these applications, finding enough concurrency remains a challenge in program design. To address this challenge, in the P¯a¯nini project we are looking at reconciling concurrent program design goals with modular program design goals. The main idea is that if programmers improve the modularity of their programs they should get concurrency for free. In this work we describe one of our directions to reconcile these two goals by enhancing Gang-of-Four (GOF) object-oriented design patterns. GOF patterns are commonly used to improve the modularity of object-oriented software. These patterns describe strategies to decouple components in design space and specify how these components should interact. Our hypothesis is that if these patterns are enhanced to also decouple components in execution space applying them will concomitantly improve the design and potentially available concurrency in software sys...
