2021-03-18	simulator: Add the CPU power model from iCanCloud/E-mc2	Hongyu
	This change implements the CPU energy model with p-states from iCanCloud/E-mc2: - Only pushed a portion of the code for discussion as not sure if the idea is on track. - Inline comments have been added, and formal documents will follow once the model is finalized. - The p-state power consumptions are currently hard-coded in a companion object, which should be improved in the next PR(s). Breaking Changes - CpuPowerModel: directly interact with the machine it is measuring. - SimBareMetalMachine: expose the speeds of its CPU cores and its clock instant.
2021-03-17	simulator: Make hypervisors generic for the resource type	Fabian Mastenbroek
	This change moves the hypervisor implementations to the opendc-simulator-resources module and makes them generic to the resource type that is being used (e.g., CPU, disk or networking).
2021-03-16	simulator: Add generic framework for resource consumption modeling	Fabian Mastenbroek
	This change adds a generic framework for modeling resource consumptions and adapts opendc-simulator-compute to model machines and VMs on top of this framework. This framework anticipates the addition of additional resource types such as memory, disk and network to the OpenDC codebase.
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.
2021-01-11	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.
2020-12-31	Update to kotlinx-coroutines 1.4.2	Fabian Mastenbroek

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	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.
