2022-11-13refactor: Replace use of CoroutineContext by DispatcherFabian Mastenbroek
This change replaces the use of `CoroutineContext` for passing the `SimulationDispatcher` across the different modules of OpenDC by the lightweight `Dispatcher` interface of the OpenDC common module.
2022-11-13refactor(sim/core): Re-implement SimulationScheduler as DispatcherFabian Mastenbroek
This change updates the `SimulationScheduler` class to implement the `Dispatcher` interface from the OpenDC Common module, so that OpenDC modules only need to depend on the common module for dispatching future task (possibly in simulation).
2022-10-21refactor(sim/flow): Remove old flow simulatorFabian Mastenbroek
This change removes the old version of the flow simulator from the OpenDC repository. The old version has been replaced by the new flow2 framework which is able to simulate flows more efficiently.
2022-10-21feat(sim/flow): Support flow transformationsFabian Mastenbroek
This change adds a new component, FlowTransform, which is able to transform the flow from one component to another, based on some inversible transformation. Such as component is useful when converting between different units of flow between different components.
2022-10-21perf(sim/flow): Add support for multi-flow stagesFabian Mastenbroek
This change adds support for creating nodes in a flow graph that support multiple inputs and outputs directly, instead of our current approach where we need to re-implement the `FlowConsumerContext` interface in order to support multiple inputs or outputs.
2022-10-06style: Eliminate use of wildcard importsFabian Mastenbroek
This change updates the repository to remove the use of wildcard imports everywhere. Wildcard imports are not allowed by default by Ktlint as well as Google's Java style guide.
2022-10-05refactor(sim/core): Rename runBlockingSimulation to runSimulationFabian Mastenbroek
This change renames the method `runBlockingSimulation` to `runSimulation` to put more emphasis on the simulation part of the method. The blocking part is not that important, but this behavior is still described in the method documentation.
2022-10-05refactor(sim/core): Use SimulationScheduler in coroutine dispatcherFabian Mastenbroek
This change updates the implementation of `SimulationDispatcher` to use a (possibly user-provided) `SimulationScheduler` for managing the execution of the simulation and future tasks.
2021-10-05perf(experiments): Add benchmark for Capelin experimentFabian Mastenbroek
2021-10-03feat(simulator): Expose CPU time counters directly on hypervisorFabian Mastenbroek
This change adds a new interface to the SimHypervisor interface that exposes the CPU time counters directly. These are derived from the flow counters and will be used by SimHost to expose them via telemetry.
2021-10-03refactor(simulator): Migrate to flow-based simulationFabian Mastenbroek
This change renames the `opendc-simulator-resources` module into the `opendc-simulator-flow` module to indicate that the core simulation model of OpenDC is based around modelling and simulating flows. Previously, the distinction between resource consumer and provider, and input and output caused some confusion. By switching to a flow-based model, this distinction is now clear (as in, the water flows from source to consumer/sink).
