Performance updates (#314)

2025-03-18T06:26:35+00:00

Added Fragment scaling (#296)

2025-01-24T12:54:59+00:00

* 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

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

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

feat(sim/compute): Add completion parameter to startWorkload

2022-10-28T10:03:38+00:00

This change updates the interface of `SimMachine#startWorkload` to
introduce a parameter `completion` that is invoked when the workload
completes either succesfully or due to failure.

This functionality has often been implemented by wrapping a
`SimWorkload` and catching its exceptions. However, since this
functionality is used in all usages of `SimMachine#startWorkload` we
instead embed it into `SimMachine` itself.

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.

build: Switch to Spotless for formatting

2022-10-06T12:46:56+00:00

This change updates the build configuration to use Spotless for code
formating of both Kotlin and Java.

style: Eliminate use of wildcard imports

2022-10-06T10:51:27+00:00

This change updates the repository to remove the use of wildcard imports
everywhere. Wildcard imports are not allowed by default by Ktlint as
well as Google's Java style guide.

refactor(sim/compute): Simplify SimHypervisor class

2022-09-22T20:37:50+00:00

This change simplifies the SimHypervisor class into a single
implementation. Previously, it was implemented as an abstract class with
multiple implementations for each multiplexer type. We now pass the
multiplexer type as parameter to the SimHypervisor constructor.

refactor(sim/compute): Make interference domain independent of profile

2022-09-22T12:50:00+00:00

This change updates the virtual machine performance interference model
so that the interference domain can be constructed independently of the
interference profile. As a consequence, the construction of the topology
now does not depend anymore on the interference profile.
