This change updates the compute support library to load the VM
interference model via the OpenDC trace library, which provides a
generic interface for reading interference models associated with
workload traces.
|
|
This change contains a rewrite of the OpenDC web runner implementation,
which now supports terminating simulations when exceeding a deadline, as
well as executing multiple simulation jobs at the same time.
Furthermore, we have extracted the runner from the command line
interface, so that we can offer this functionality as a library in the
future.
|
|
This change moves most of the Quarkus build configuration into buildSrc
so it can possibly be re-used for other modules.
|
|
This change fixes an issue where the results of the Quarkus tests where
not included in the aggregated JaCoCo test report, due to it not using
the official Gradle JaCoCo plugin.
This change defines a new configuration that exposes the execution data
generated by Quarkus to the aggregation plugin.
|
|
This change updates the web API to use Quarkus 2.8.1.Final. This release
fixes an issue we had with local extensions failing to build due to some
build directories missing.
|
|
This change updates the Node package manager used by the OpenDC web UI
build from Yarn to NPM, which is included by default in the Node
distributions that are used by node-gradle.
|
|
This change removes the use of lint-staged from the project. These steps
should be managed by the Gradle build logic, while we keep the Next.js
build logic as minimal as possible.
|
|
This change updates the ESLint dependencies to operate correctly in
Windows environments.
|
|
This change updates the web UI and API to support unauthenticated user
access. Such functionality is helpful when there is just a single user
that wants to try OpenDC.
|
|
This chnage add a workaround for the issues that appear when building
the Quarkus application due to it accessing the build files of the other
local modules.
|
|
This change adds support for serving the web UI of OpenDC while in the
development mode of the API server.
|
|
This change adds a new Quarkus extension that is able to serve the
OpenDC web interface via the Quarkus deployment of OpenDC.
|
|
This change updates the build process to build a static WebJar out of
the OpenDC web UI module. This allows us to embed the UI inside the
development distribution of OpenDC for other users to readily deploy it.
|
|
This change adds support for building the OpenDC web interface project
that uses Next.js using Gradle. This enables a single build pipeline
using Gradle.
|
|
|
|
This change updates the web interface to use next-global-css instead of
next-transpile-modules. This approach is more efficient since it does
not require transpilation of the dependencies.
|
|
This change removes the use of next/image from the project. Although it
is recommended by the Next.js project to use this component, it is not
compatible currently with static export.
|
|
This change updates the build script to fix the aggregation step for the
JaCoCo coverage reports that are submitted to Codecov. Previously, not
all modules were properly included in the report.
|
|
This change updates the Docker deployment configuration for the new web
API implemented in Kotlin. The new API migrates to Postgres.
Furthermore, with this change, we move the Dockerfiles to their
corresponding module.
|
|
This change updates the web interface in React to be compatible with the
new API written in Kotlin. Several changes have been made in the new API
to ensure consistency.
|
|
This change updates the web runner implementation to use the new API
client introduced in the previous commit.
|
|
This change implements a simple client for the OpenDC REST API into a
separate module. This allows other users to use this module as well.
|
|
This change adds support for dynamically selecting the appropriate JSON
type for the current database. For Postgres, this will be the JSONB
type, while for H2 this is either the BLOB or JSON type.
|
|
This change adds the initial implementation of the new API server in Kotlin,
replacing the old API written in Python. The implementation uses Quarkus,
RESTEasy, and Hibernate to implement the new API endpoints.
The reason for replacing the old API server is unifying the build and
deployment toolchains, reducing the number of technologies necessary to
work with OpenDC. Furthermore, we envision bundling the entire OpenDC
project into a single distributions, allowing users to launch their own
deployment trivially.
|
|
This change adds a unified communication protocol in form of the module
opendc-web-proto which contains the classes that form the communication
protocol of OpenDC's API v2.
By having the protocol in a separate module, we can utilize the classes
in both server and client.

This change removes the opendc-platform module from the project. This
module represented a Java platform which was previously used for sharing
a set of dependency versions between subprojects. However, with the
version catalogue that was added by Gradle, we currently do not use the
platform anymore.

This change fixes an issue with the creation of topologies in the
frontend. Previously, the frontend relied on Redux to update the state.
However, since we removed the reliance on Redux, we also need to create
a new topology using the functions from React Query to actually send a
request to the API server.
|
|
This change updates the Docker Compose configuration to properly deploy
the API server, by passing the necessary Auth0 information to it.
|
|
This change adds support for custom audience values in the web runner.
If the audience used by the user is different from the default value
(https://api.opendc.org/v2/), then the runner fails to obtain a valid
access token for the API.
|
|
This change updates the OpenDC codebase to use OpenTelemetry v1.11,
which stabilizes the metrics API. This stabilization brings quite a few
breaking changes, so significant changes are necessary inside the OpenDC
codebase.

This change redesigns the ComputeMonitor interface to reduce the number
of memory allocations necessary during a collection cycle.
|
|
This change redesigns the virtual machine interference algorithm to have
a fixed memory usage per `VmInterferenceModel` instance. Previously, for
every interference domain, a copy of the model would be created, leading
to OutOfMemory errors when running multiple experiments at the same
time.
|
|
This change renames the `opendc-simulator-resources` module into the
`opendc-simulator-flow` module to indicate that the core simulation
model of OpenDC is based around modelling and simulating flows.
Previously, the distinction between resource consumer and provider, and
input and output caused some confusion. By switching to a flow-based
model, this distinction is now clear (as in, the water flows from source
to consumer/sink).
|
|
This change drops the requirement for a clock parameter when
constructing a ComputeMetricExporter, since it will now derive the
timestamp from the recorded metrics.

This change adds a new API for writing traces in a trace format.
Currently, writing is only supported by the OpenDC VM format, but over
time the other formats will also have support for writing added.
|
|
This change updates the workload sampling implementation to be more
flexible in the way the workload is constructed. Users can now sample
multiple workloads at the same time using multiple samplers and use them
as a single workload to simulate.
|
|
This change adds support for creating flexible topologies by creating a
TopologyFactory interface that is responsible for configuring the hosts
of a compute service.
|
|
This change creates a new module for doing simulations with virtual
machine workloads. We have found that a lot of code in the Capelin
experiments code is being re-used by non-experiment modules.
|
|
This change standardizes the metrics emitted by SimHost instances and
their guests based on the OpenTelemetry semantic conventions. We now
also report CPU time as opposed to CPU work as this metric is more
commonly used.
|
|
This change updates the OpenDC compute service implementation with
multiple meters that follow the OpenTelemetry conventions.
|
|
This change refactors the telemetry implementation by creating a
separate MeterProvider per service or host. This means we have to keep
track of multiple metric producers, but that we can attach resource
information to each of the MeterProviders like we would in a real world
scenario.
|
|
This change moves the fault injection logic directly into the
opendc-compute-simulator module, so that it can operate at a higher
abstraction. In the future, we might again split the module if we can
re-use some of its logic.
|
|
This change updates the dependencies of the OpenDC frontend module.
