2021-06-02	simulator: Add uniform interface for resource metrics	Fabian Mastenbroek
	This change adds a new interface to the resources library for accessing metrics of resources such as work, demand and overcommitted work. With this change, we do not need an implementation specific listener interface in SimResourceSwitchMaxMin anymore. Another benefit of this approach is that updates will be scheduled more efficiently and progress will only be reported once the system has reached a steady-state for that timestamp.
2021-06-01	simulator: Centralize resource logic in SimResourceInterpreter	Fabian Mastenbroek
	This change introduces the SimResourceInterpreter which centralizes the logic for scheduling and interpreting the communication between resource consumer and provider. This approach offers better performance due to avoiding invalidating the state of the resource context when not necessary. Benchmarks show in the best case a 5x performance improvement and at worst a 2x improvement.
2021-05-18	chore: Address deprecations due to Kotlin 1.5	Fabian Mastenbroek
	This change addresses the deprecations that were caused by the migration to Kotlin 1.5.
2021-05-07	build: Use Gradle version catalog	Fabian Mastenbroek
	This change adds support for the Gradle version catalog feature in our build configuration. This allows us to have a single file, gradle/libs.versions.toml, which contains all the dependency versions used in this project.
2021-05-06	build: Use type-safe project accessors	Fabian Mastenbroek
	This change updates the build scripts to use type-safe project accessors when specifying build dependencies between modules.
2021-05-04	simulator: Update power draw on machine draw	Fabian Mastenbroek
	This change fixes an issue where the power draw of a machine is initially zero and does not update until the CPU usage is higher than zero, while the idle power is the machine is not actually zero.
2021-05-03	simulator: Introduce SimResourceScheduler	Fabian Mastenbroek
	This change introduces the SimResourceScheduler interface, which is a generic interface for scheduling the coordination and synchronization between resource providers and resource consumers. This interface replaces the need for users to manually specify the clock and coroutine context per resource provider.
2021-05-03	simulator: Fix compute benchmarks	Fabian Mastenbroek
	This change fixes an issue with the compute benchmarks where the workload was being re-used across iterations.
2021-05-03	simulator: Add generic approach for reporting resource events	Fabian Mastenbroek
	This change introduces a generic approach for reporting resource events to resource consumers. This way we reduce the boilerplate of the SimResourceConsumer interface.
2021-05-03	simulator: Simplify scheduling logic of resource aggregator	Fabian Mastenbroek
	This change simplifies the scheduling logic of the resource aggregator. Previously, after each scheduling cycle, each aggregated input was interrupted. With the new approach, the scheduler can decide which ones of the inputs to send a new command to.
2021-04-25	build: Migrate to flat project structure	Fabian Mastenbroek
	This change updates the project structure to become flattened. Previously, the simulator, frontend and API each lived into their own directory. With this change, all modules of the project live in the top-level directory of the repository. This should improve discoverability of modules of the project.
