2021-10-05	perf(experiments): Add benchmark for Capelin experiment	Fabian Mastenbroek

2021-10-05	perf(simulator): Do not prune invocations on sync engine invocation	Fabian Mastenbroek

2021-10-03	feat(simulator): Expose CPU time counters directly on hypervisor	Fabian 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.
2021-10-03	perf(simulator): Reduce field accesses in FlowConsumerContextImpl	Fabian Mastenbroek
	This change updates the implementation of FlowConsumerContextImpl to reduce the number of field accesses by storing the flags of the connection inside a single integer.
2021-10-03	perf(simulator): Make convergence callback optional	Fabian Mastenbroek
	This change adds two new properties for controlling whether the convergence callbacks of the source and consumer respectively should be invoked. This saves a lot of unnecessary calls for stages that do not have any implementation of the `onConvergence` method.
2021-10-03	fix(simulator): Fix loss computation for UPS and PDU	Fabian Mastenbroek
	This change fixes the loss computation for both the UPS and PDU implementation that was broken due to the new pushing mechanism. We implement a new class FlowMapper that can be used to map the flow pushed by a `FlowSource` using a user-specified method.
2021-10-03	refactor(simulator): Create separate callbacks for remaining events	Fabian Mastenbroek
	This change creates separate callbacks for the remaining events: onStart, onStop and onConverge.
2021-10-03	refactor(simulator): Remove capacity event	Fabian Mastenbroek
	This change removes the Capacity entry from FlowEvent. Since the source is always pulled on a capacity change, we do not need a separate event for this.
2021-10-03	refactor(simulator): Remove failure callback from FlowSource	Fabian Mastenbroek
	This change removes the `onFailure` method from FlowSource. Instead, the FlowConsumer will receive the reason for failure of the source.
2021-10-03	perf(simulator): Manage flow connection timers more efficiently	Fabian Mastenbroek
	This change reduces the number of operations necessary to manage the timers of a flow connection.
2021-10-03	perf(simulator): Do not use set for tracking convergence	Fabian Mastenbroek
	This change removes the use of a HashSet for tracking the flow connections that can converge. A HashSet requires an allocation for every addition, which caused a significant overhead. The new approach using an ArrayDeque should not allocate any memory.
2021-10-03	refactor(simulator): Separate push and pull flags	Fabian Mastenbroek
	This change separates the push and pull flags in FlowConsumerContextImpl, meaning that sources can now push directly without pulling and vice versa.
2021-10-03	refactor(simulator): Migrate to flow-based simulation	Fabian 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).
