* Batteries are implemented. Small problem with the deletion when running larger workloads.
Added mock files for the Battery implementation. Updated the Carbon Model to allow for multiple receivers of CarbonIntensity
* Implemented batteries in OpenDC.
* Spotless applied

* Added maxCpuDemand to TraceWorkload, don't know if this will be needed so might remove later.
Updated SimTraceWorkload to properly handle creating checkpoints
Fixed a bug with the updatedConsumers in the FlowDistributor
Implemented a first version of scaling the runtime of fragments.
* small update
* updated tests to reflect the changes in the checkpointing model
* Updated the checkpointing tests to reflect the changes made
* updated wrapper-validation-action
* Applied spotless

* Updated the FlowDistributor to work in more cases and be more performant.
* Removed old FlowDistributor

state. (#283)
|
|
* Restructured opendc-simulator-flow.
Renamed Multiplexer to FlowDistributor.
* spotless applied
* Added FlowDistributor topologies back
|
|
Multiplexer is using MaxMinFairness given that this is currently the default and only fairness available in OpenDC. (#280)
|
|
* Fixed the Multiplexer.java to properly divide the supply over the different consumers.
Fixed a bug where fragments were being loaded in reversed order.
* Optimized the Multiplexer.java, by only updating the supply of the consumer that updated its demand when possible.

consumerIndex variable to FlowEdge.java (#275)

* Fixed a small bug making the power source not update energy usage properly
* small update to the test
|
|
* 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.

This change fixes an issue with the `ForwardingFlowMultiplexer` where
the capacity of new outlets were not recorded correctly due to no
handler being attached to idle outlets, causing the `pull` events to be
disregarded.
This bug manifested in an issue where the CPU counters where reporting
negative values. This was caused by the CPU usage/demand being
subtracted from a zero capacity.

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.
|
|
This change updates the modules of OpenDC to always accept
the `InstantSource` interface as source of time. Previously we used
`java.time.Clock`, but this class is bound to a time zone which does not
make sense for our use-cases.
Since `java.time.Clock` implements `java.time.InstantSource`, it can be
used in places that require an `InstantSource` as parameter. Conversion
from `InstantSource` to `Clock` is also possible by invoking
`InstantSource#withZone`.
|
|
This change adds a new method to `FlowStage` called `sync()` which
enables users to synchronously update the stage at the current
timestamp.
This functionality is neccessary to support snapshotting since we need
to synchronize the state of the `FlowStage` before creating a snapshot
of the workload.
|
|
This change re-implements the OpenDC compute simulator framework using
the new flow2 framework for modelling multi-edge flow networks. The
re-implementation is written in Java and focusses on performance and
clean API surface.

|
|
This change implements a new `FlowMultiplexer` that forwards the inputs
directly to one of the pre-allocated outputs.
|
|
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.
|
|
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.
