opendc.git/opendc-compute/opendc-compute-service/src/test/kotlin/org/opendc/compute/service, branch master

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

All simulation are now run with a single CPU and single MemoryUnit. multi CPUs are combined into one. This is for performance and explainability. (#255)

2024-09-16T09:29:26+00:00

Added max number of failures (#254)

2024-09-12T13:32:47+00:00

* Added a max failure for tasks. If tasks fail more times, they get cancelled

* Added maxNumFailures to the frontend

* Updated tests

Renamed input files and internally server is changed to task (#246)

2024-08-27T11:48:46+00:00

* 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

Cpu fix (#208)

2024-03-05T15:50:35+00:00

* Updated the topology format to JSON. Updated TopologyReader.kt to handle JSON filed. Added documentation for the new format.

refactor(compute/service): Do not split interface and implementation

2022-11-27T20:50:13+00:00

This change inlines the implementation of the compute service into the
`ComputeService` interface. We do not intend to provide multiple
implementations of the service. In addition, this approach makes more
sense for a Java implementation.

refactor(compute/service): Expose state directly to clients

2022-11-27T20:49:39+00:00

This change updates the implementation of the compute service to expose
state to clients created by the compute service.

refactor(compute/api): Do not suspend in compute API

2022-11-27T20:49:33+00:00

This change updates the API interface of the OpenDC Compute service to
not suspend execution using Kotlin Coroutines.

The suspending modifiers were introduced in case the ComputeClient would
communicate with the service over a network connection. However, the main
use-case has been together with the ComputeService, where the suspending
modifiers only frustrate the user experience when writing experiments.

Furthermore, with the advent of Project Loom, it is not necessarily a
problem to block the (virtual) thread during network communications.

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.
