Queues

Sequential, contracted, concurrent and distributed queue implementations. All concepts introduced in those examples are considered prior knowledge and are presented here as a refresher before we enter the realm of real-time programming.

Distributed Atomic Actions

Bundling a number of sequential operations into a concurrent entity which is executed under real-time constraints and succeeds or fails according to the rules of atomic actions (either succeeds in full or not at all).

The chosen example simulates the concurrent movement of three flight control surfaces (all with their own specific timing constraints) and the overall monitoring of a successful maneuver. If any surface fails to move in synchrony then all surfaces are informed and move to their fail-safe positions.

Swarm

This is an OpenGL based, 3d graphics simulator for concurrent and real-time experimentation of planning, coordination, synchronization and scheduling.
