potsdam.de In this position paper we propose to extend an existing delegation-based machine model with concurrency primi-tives. The original machine model which is built on the con-cepts of objects, messages, and delegation, provides support for languages enabling multi-dimensional separation of con-cerns (MDSOC). We propose to extend this model with an actor-based concurrency model, allowing for both true par-allelism as well as lightweight concurrency primitives such as coroutines. In order to demonstrate its expressiveness, we informally describe how three high-level languages sup-porting different concurrency models can be mapped onto our extended machine model. We also provide an outlook on the extended model’s potential to support concurrency-related MDSOC features. 1
