* 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.

* 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.

CPUs are combined into one. This is for performance and explainability. (#255)
|
|
* Updated the checkpointing system to use SimTrace. The checkpoint model can now also scale, which means the interval between checkpoints can increase or decrease over time.
* spotless kotlin
* Fixed tests
* spotless apply
|
|
* Started on reimplementing the SimTrace implementation
* updated trace format. Fragments now do not have a deadline, but a duration. The Fragments are executed in order.
|
|
* Updated SimTrace to use a single ArrayDeque instead of three separate lists for deadline, cpuUsage, and coreCount
* Renamed input files to tasks.parquet and fragments.parquet. Renamed server to task. OpenDC nows exports tasks.parquet instead of server.parquet

* Fixed a problem which caused the CPU limit to be much lower than it should be.
AllocationPolicy is now properly exposed to the user
* Fixed tests
* spotless kotlin

* Updated the power models and added tests
* Updated test topologies
|
|
* sync with the master branch
* rebase
* multimodel - simulation is currently run as many times as you can see a model
* factory method - handles models without given params
* removed redundant flags
* modelType
* flags removed
* implemented output into a folder
* multimodel ipynb setup - to be implemented and also ran as a python script, when the simulation occurs
* towards a mutimodel python implementation - issue observed - the saved files have same data?
* json parsing handles now lists for topology, workloads, allocaitonPolicies, powerModels
* scenarioFile inputs lists, and creates multiple combinations of scenarios
* multi-model prediction repaired, now we predict using multiple models
* commit before removing powerModel from scenario

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 removes the use of a Spy object from the TestInlet class.
Since the Spy is not actually used in our tests, we remove it due to the
high initialization cost.
|
|
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 `SimulationScheduler` class to implement the
`Dispatcher` interface from the OpenDC Common module, so that OpenDC
modules only need to depend on the common module for dispatching future
task (possibly in simulation).
|
|
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 updates the interface of `SimWorkload` to support
snapshotting workloads. We introduce a new method `snapshot()` to this
interface which returns a new `SimWorkload` that can be started at a
later point in time and on another `SimMachine`, which continues
progress from the moment the workload was snapshotted.
|
|
This change updates the implementation of `SimMachineContext` to report
exceptions thrown in `onStop` as suppressed exceptions if an exception
caused the workload to stop.
|
|
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 adds a new static method `chain` to `SimWorkloads` to chain
multiple workloads sequentially.
|
|
This change updates the interface of `SimMachineContext` to allow
workloads to reset all resources provided by the machine to the
workload. This allows us to implement a `SimWorkload` that can compose
multiple workloads.
|
|
This change introduces a new class SimWorkloads which provides
construction methods for the standard workloads available in OpenDC.
