2021-03-07	compute: Extract API from compute service	Fabian Mastenbroek
	This change extracts the API for the OpenDC Compute service into a separate module to establish a clearer boundary between the interface meant for consumers and interfaces meant for the the serve implementation.
2021-03-07	compute: Convert Server to stateful interface	Fabian Mastenbroek
	This change converts the Server data class which can be used as a stateful object to control an instance running in the cloud.
2021-03-07	compute: Make VirtProvisoningService responsible for Server lifecycle	Fabian Mastenbroek
	This change refactors the OpenDC Compute module so that the VirtProvisioningService is now responsible for managing the lifecycle of Server objects as opposed to the VirtDriver and BareMetalDriver previously.
2021-03-07	compute: Remove ServiceRegistry fields	Fabian Mastenbroek
	This change removes the use of ServiceRegistry in the OpenDC compute module. It was not actually being used by any of the code and we are moving to another interface in the future.
2021-03-07	compute: Separate cloud compute layer from bare-metal layer	Fabian Mastenbroek
	This change separates the cloud compute layer in OpenDC (e.g., Server) from the bare-metal layer (e.g., Node), such that Node and BareMetalDriver are unaware of the existence of Server and co.
2021-03-07	compute: Pass simulation workload via image metadata	Fabian Mastenbroek
	This change removes the SimWorkloadImage implementation and changes Image to a data class without workload. Simulation workloads should now be pased via image metadata as the image storage should be unaware of any simulation details.
2021-03-06	sim: Implement energy models from CloudSim (#79)	Hongyu
	This commit implements the energy models that are present in CloudSim: 1. Constant 2. Linear 3. Cubic 4. Square root 5. Interpolation based on data.
2021-02-23	Use Java Platform for shared dependency constraints	Fabian Mastenbroek
	This change uses the Java Platform functionality from Gradle to enable shared dependency constraints across modules.
2021-02-23	Utilize version constraints for shared versions	Fabian Mastenbroek
	This change updates the Gradle configuration to utilize version constraints to force the same dependency version across modules.
2021-02-23	Move dependency versions to gradle.properties	Fabian Mastenbroek
	This change moves the version of the dependencies from buildSrc to gradle.properties to prevent recompilation when changing dependency versions.
2021-02-23	Extract testing conventions from Kotlin conventions	Fabian Mastenbroek
	This change extracts the configuration for test from the Kotlin library conventions.
2021-02-23	Remove unnecessary dependencies on JUnit Platform Launcher	Fabian Mastenbroek
	This change removes unnecessary dependencies on JUnit Platform launcher from the repository. Previously, the launcher was used to bootstrap tests for Gradle when it did not natively support JUnit Platform. Gradle now has native support for JUnit Platform, so the dependency is not needed anymore.
2021-01-11	Add support for hypervisor selection	Fabian Mastenbroek
	This change allows users to select the hypervisor scheduler to use when deploying hypervisors onto bare-metal machines.
2021-01-11	Add hypervisor supporting space-shared VMs	Fabian Mastenbroek
	This change adds a new hypervisor implementation that supports virtual machine that have exclusive access to resources (e.g., CPU).
2021-01-11	Convert to pull-based workload model	Fabian Mastenbroek
	This change converts the low-level workload model to be pull-based. This reduces the overhead that we experienced with our previous co-routine based approach.
2021-01-07	Refactor workflow service to schedule tasks onto VMs	Fabian Mastenbroek
	This change updates the workflow service to delegate the resource scheduling logic to the virtualized resource provisioner.
2021-01-03	Integrate event tracer in SimVirtProvisioningService	Fabian Mastenbroek

2020-10-05	Address compilation warnings	Fabian Mastenbroek

2020-10-05	Move power models outside opendc-core	Fabian Mastenbroek

2020-10-05	Move failure models to separate module	Fabian Mastenbroek

2020-10-04	Extract simulation-related code from OpenDC Compute (core)	Fabian Mastenbroek
	This change splits the opendc-compute module into two modules: 1. opendc-compute-core The interfaces and APIs that represent a IaaS platform. 2. opendc-compute-simulator The implementation of these interfaces using simulation components from opendc-simulator-compute.
2020-10-04	Reimplement performance interference in opendc-simulator-compute	Fabian Mastenbroek
	This change reimplements the performance interference model originally implemented for the SimpleVirtDriver class, for SimHypervisor.
2020-10-04	Migrate codebase to opendc-simulator-compute	Fabian Mastenbroek
	This change updates the remainder of the codebase to use the opendc-simulator-compute module for the simulation of workloads.
2020-10-03	Implement VirtDriver using opendc-simulator-compute module	Fabian Mastenbroek
	This change adds an implementation of the VirtDriver interface that uses the functionality provided by the opendc-simulator-compute module.
2020-10-02	Implement BareMetalDriver using SimMachine	Fabian Mastenbroek
	This change creates an implementation of the BareMetalDriver interface using the simulation logic of SimMachine. This implementation will eventually replace the SimpleBareMetalDriver implementation.
2020-10-02	Add opendc-simulator-compute module	Fabian Mastenbroek
	This change adds an opendc-simulator-compute module which contains interfaces related to simulating compute workloads. For future changes, we intend to decouple the simulation part from the opendc-compute module.
2020-10-01	Add explicit API visibility	Fabian Mastenbroek
	This change adds explicit visibility modifiers to the public interfaces and enables Kotlin 1.4's explicit API mode.
2020-10-01	Migrate to org.opendc namespace	Fabian Mastenbroek
	This change moves the OpenDC simulator codebase to the org.opendc namespace of which we control the domain. Previously, we used the com.atlarge package of which we did not control the domain, which might lead to difficulties in the future.
2020-10-01	Move OpenDC modules into simulator root	Fabian Mastenbroek
	This change moves the OpenDC modules previously living in the simulator/opendc directory to the simulator directory itself given that we do not make a distinction between OpenDC and odcsim anymore.
