Rewrote the FlowEngine (#256)

2024-10-25T11:32:41+00:00

* 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.

* fixed merge conflicts

* Updated M3SA paths.

* Fixed small typo

rewritten the checkpointing model (#250)

2024-09-10T10:15:05+00:00

* 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

Updated package versions, updated web server tests. (#207)

2024-03-05T12:23:57+00:00

* Updated all package versions including kotlin. Updated all web-server tests to run.

* Changed the java version of the tests. OpenDC now only supports java 19.

* small update

* test update

* new update

* updated docker version to 19

* updated docker version to 19

Updated metrics and parquet output (#195)

2024-02-14T10:52:32+00:00

* Updated metrics and parquet output

* fixed typos

Updated tests to run successfully (#187)

2023-12-14T20:13:40+00:00

* made sure all tests run

* fixed typo

* executed spotlessApply

* added back web-server tests

* updated SimTraceWorkloadTest

* commented CapelinRunneer and GreenifierRunner tests

* altered codecov execution

* changed codecov

refactor: Replace use of CoroutineContext by Dispatcher

2022-11-13T17:42:01+00:00

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.

refactor: Use InstantSource as time source

2022-11-13T15:24:47+00:00

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`.

feat(sim/compute): Add support for snapshotting workloads

2022-10-31T14:50:36+00:00

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.

refactor(sim/compute): Re-implement using flow2

2022-10-21T20:13:04+00:00

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.
