Concurrency is not a new idea…. Concurrency was first developed by the ancient Babylonians.. They thought about stuff, walked, and chewed gum … all at the same time.. 1. 7.1 System Model. In order to talk about deadlocks in a system, it’s helpful to have a model of the system. A . system consists of a set of resources. The resources can be grouped into types. Processes compete to have (unique) access to instances of the types. DEADLOCKS. To be discussed…. Definition of deadlock. Example of deadlock. Resource allocation graph.
