Towards Runtime Adaptation of Actor Systems [article]

Ian Cassar
2017 arXiv   pre-print
We implement the identified adaptations as an extension of an existing Runtime Verification tool for actor-systems, thereby creating a RA framework for monitoring and mitigating actor systems.  ...  We thus identify a number of generic adaptations that can be applied to any actor system, regardless of its design and the code that it executes.  ...  Each objective contributes in its own way towards developing a more refined Runtime Adaptation framework for actor systems.  ...
