2024-10-29Updated all floats to Doubles (#257)Dante Niewenhuis
* Updated tests Changed all floats into doubles to have consistency over the whole framework Made a small update to the multiplexer to better push through supply and demand Fixed small typo Updated M3SA paths. fixed merge conflicts Removed unused components. Updated tests. Improved checkpointing model Improved model, started with SimPowerSource implemented FailureModels and Checkpointing First working version midway commit first update All simulation are now run with a single CPU and single MemoryUnit. multi CPUs are combined into one. This is for performance and explainability. * Updated test memory

2022-11-27refactor(compute/service): Do not split interface and implementationFabian Mastenbroek
This change inlines the implementation of the compute service into the `ComputeService` interface. We do not intend to provide multiple implementations of the service. In addition, this approach makes more sense for a Java implementation.
2022-11-27refactor(compute/api): Do not suspend in compute APIFabian Mastenbroek
This change updates the API interface of the OpenDC Compute service to not suspend execution using Kotlin Coroutines. The suspending modifiers were introduced in case the ComputeClient would communicate with the service over a network connection. However, the main use-case has been together with the ComputeService, where the suspending modifiers only frustrate the user experience when writing experiments. Furthermore, with the advent of Project Loom, it is not necessarily a problem to block the (virtual) thread during network communications.
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.
