This pull request updates the build and runtime dependencies used by OpenDC to
their latest version compatible with the project.
## Implementation Notes :hammer_and_pick:
* Update simulator dependency versions
* Fix conversion from UUID to Binary
|
|
This change fixes an issue with the metric exporting code in OpenDC
where a UUID is not converted correctly into a `Binary` object that is
consumed by the Apache Parquet library.
|
|
This change updates the simulator dependencies to the latest available
version where possible.
|
|
This pull request fixes an issue where the distributed strategies for the
TensorFlow experiments did not work correctly.
## Implementation Notes :hammer_and_pick:
* Limit growth rate for trace construction
* Derive device statistics directly from SimMachine
* Always recompute power usage when a `SImBareMetalMachine` converges
* Add a test case for `MirroredStrategy`
|
|
This change fixes an issue in the `SimBareMetalMachine` implementation
where the power usage was only updated after a non-zero duration. However,
this would mean that OpenDC would possibly report incorrect power usage
values when multiple convergence calls occured at the same timestamp.
|
|
This change updates the implementation of SimTFDevice to directly use
the metrics provided by the `SimBareMetalMachine` class, instead of
computing these metrics itself.
|
|
This change fixes an issue where the `SimTrace.Builder` would quickly
allocate too much memory when constructing a trace, due to doubling the
array sizes each time. Instead, we use the approach used by `ArrayList`,
where we increase the array size by 50% every step.
|
|
This pull request updates the OpenDC trace API to support proper specification
of a schema of the tables exposed by the traces. This functionality makes it easier
for the API consumer to understand the types exposed by the API.
## Implementation Notes :hammer_and_pick:
* Introduce type system for trace API
* Add benchmarks for odcvm trace format
* Add benchmarks for Azure trace format
* Add conformance suite for OpenDC trace API
## External Dependencies :four_leaf_clover:
* N/A
## Breaking API Changes :warning:
* Removal of typed `TableColumn`. Instead, `TableColumn` instances are now
used to describe the columns belonging to some table.
* `TableReader` and `TableWriter` do not support accessing arbitrary objects
anymore. Instead, only the types supported by the type system are exposed.
|
|
This change adds a re-usable test suite for the interface of the OpenDC
trace API, so implementors can verify whether they match the
specification of the interfaces.
|
|
This change adds JMH benchmarks for the parsing logic of the Azure VM
trace format in order to catch performance regressions.
|
|
This change adds JMH benchmarks for the parsing logic of the OpenDC VM
trace format in order to catch performance regressions.
|
|
This change updates the trace API by introducing a limited type system
for the table columns. Previously, the table columns could have any
possible type representable by the JVM. With this change, we limit the
available types to a small type system.

This pull request adds a new Quarkus extension that starts an embedded
experiment runner while the user is in development mode. This allows users
to deploy the entire OpenDC stack by using the `quarkusDev` command.
By default, the experiment runner will only run experiments on one thread.
Though, this setting is configurable.
## Implementation Notes :hammer_and_pick:
* Use correct group for Gradle modules
* Support client construction without AuthController
* Move runner CLI into separate configuration
* Remove module nesting in Quarkus extension
* Add Quarkus extension for OpenDC runner
* Add initial server distribution
## Breaking API Changes :warning:
* N/A
|
|
This change adds a distribution that contains the OpenDC web server
implementation based on Quarkus. This distribution should be used by
advanced users that whish to deploy a custom OpenDC instance.
|
|
This change adds a Quarkus extension that hosts the OpenDC web runner
for a (potentially local) OpenDC API instance. This functionality
enables a simplified developer experience by allowing users to spawn the
complete OpenDC stack with a single command.
|
|
This change updates the OpenDC web UI Quarkus extension to live
completely in the `opendc-web` directory, as opposed to adding another
level of nesting. This also allows us to properly name the artifacts of
the Quarkus extension modules.
|
|
This change splits the command line interface from the OpenDC web runner
into a separate configuration. We plan to re-use the runner code for a Quarkus
extension that integrates the runner in development mode.
|
|
This change updates the `OpenDCClient` and `OpenDCRunnerClient` to
support connecting to an API that is not protected by authorization.
This is useful in a local development context where authorization is
explicitly disabled.
|
|
|
|
This pull request updates the build and runtime dependencies used by OpenDC
to their latest version compatible with the project.
## Implementation Notes :hammer_and_pick:
* Update simulator dependency versions
* Fix hotkeys support for React 18
* Update dependencies of web UI
* Remove unused dependencies
## Breaking API Changes :warning:
* N/A
|
|
This change updates the dependencies of the Next.js-based web UI to
their latest available versions where possible.
|
|
This change fixes an issue where the library for hotkeys that we
previously used does not (yet) support React 18. Instead, we switch to a
simpler solution based on React Hooks which is compatible with React 18.
|
|
This change updates the simulator dependencies to the latest available
version where possible.
|
|
This pull request updates the CI build pipeline to also build the Docker
images in order to catch any regressions in the deployment process via
Docker.
## Implementation Notes :hammer_and_pick:
* Build Docker images for build pipeline
* Reduce build steps for Docker image
* Ensure Node.js is downloaded
## Breaking API Changes :warning:
N/A
|
|
This change updates the build configuration in order to ensure that
Node.js is downloaded onto the build system. This drops an explicit
dependency on a system installation of Node.js and allows us to ensure
that the project is built against the correct Node.js version.
|
|
This change updates the Dockerfile for the web runner to reduce the
number of build steps necessary to build the web runner. Previously, the
build would also include/build the web API which is not used in the
image.

This change updates the CI build pipeline to also build the Docker
images in order to catch any regressions in the deployment process via

This pull request restructures the experiments present in the `opendc-experiments` directory
and removes the legacy OpenDC Harness. Previously, the experiments were written against
the OpenDC Harness, which facilitates generation and execution of scenarios.
However, the OpenDC Harness does not integrate well into the web-based workflow of OpenDC,
where users should be able to submit scenarios in the web interface and automatically simulate
it in the cloud, since the harness relied on a special Kotlin DSL to specify experiments.
In future pull request, we'll attempt to introduce a similar approach for specifying and
running experiments as we have done for the Radice experiments, where the entire
experiment is described in a serializable (JSON/YAML) format.
## Implementation Notes :hammer_and_pick:
* Add helper tools for FaaS simulations
* Fix infinite loop due to invalid rounding
* Convert experiment into integration test
* Add independent Capelin distribution
* Remove OpenDC Harness modules
* Remove unnecessary dependencies
## Breaking API Changes :warning:
* Removal of the OpenDC Harness modules. Instead, we now package each experiment individually.
We'll focus in the future on extracting common code from the Capelin and Radice experiments
so they can be re-used by other experiments as well.
|
|
This change removes several dependencies from the `opendc-trace-parquet`
helper module, which are part of Hadoop Common, but are not actually
used by the Parquet project.
|
|
This change removes the OpenDC Harness modules from the main repository.
We have made the decision to take a different direction regarding the
specification and execution of experiments. The design of the current
harness does not integrate well with the specification of experiments in
the web interface. The new version focuses on proper integration with
the web interface, as well as via the command line interface.
|
|
This change updates the Capelin experiments so it can be distributed and
executed independently of the main OpenDC distribution. We provide a new
command line interface for users to directly run the experiments.
Alternatively, the `CapelinRunner` class encapsulates the logic for
running the experiments and can be used programmatically.
|
|
This change removes the `TensorFlowExperiment` in favour of an
integration test that can be run during CI invocations. Given that the
experiment was not very sophisticated (in terms of data collection), we
believe it is better suited as an integration test.
|
|
This change fixes an issue with the `SimTFDevice` implementation where
very small amounts of FLOPs would cause the device to enter an infinite
loop. We now round the value up to ensure that the device always
consumes FLOPs.
|
|
This change adds a new module, opendc-faas-workload that contains
helper code for constructing simulations of FaaS-based workloads
using OpenDC. In addition, we add an integration test that demonstrates
the capabilities of the helper tool and the FaaS platform of OpenDC.
|
|
This change removes the OpenTelemetry integration from the OpenDC modules.
Previously, we chose to integrate OpenTelemetry to provide a unified way to
report metrics to the users.
Although this worked as expected, the overhead of the OpenTelemetry when
collecting metrics during simulation was considerable and lacked more
optimization opportunities (other than providing a separate API
implementation). Furthermore, since we were tied to OpenTelemetry's SDK
implementation, we experienced issues with throttling and registering
multiple instruments.
We will instead use another approach, where we expose the core metrics
in OpenDC via specialized interfaces (see #80) such that
access is fast and can be done without having to interface with
OpenTelemetry. In addition, we will provide an adapter to that is able
to forward these metrics to OpenTelemetry implementations, so we can
still integrate with the wider ecosystem.
## Implementation Notes :hammer_and_pick:
* Remove OpenTelemetry from "compute" modules
* Remove OpenTelemetry from "workflow" modules
* Remove OpenTelemetry from "FaaS" modules
* Remove OpenTelemetry from TF20 experiment
* Remove dependency on OpenTelemetry SDK
## External Dependencies :four_leaf_clover:
* N/A
## Breaking API Changes :warning:
* Metrics are not anymore directly exposed via OpenTelemetry. Instead, an adapter needs to be used to access the data via OpenTelemetry.
|
|
This change removes the dependency on the OpenTelemetry SDK. Instead,
we'll only expose metrics via the OpenTelemetry API in the future via
adapter classes.
|

This change removes the OpenTelemetry integration from the OpenDC
Tensorflow 2020 experiments. Previously, we chose to integrate
OpenTelemetry to provide a unified way to report metrics to the users.

This pull request adds the ability to access the metrics of resources modeled
by the OpenDC Compute, Workflow, FaaS, and TensorFlow services directly from
their corresponding interfaces. Previously, users would have to interact with
OpenTelemetry to obtain these values, which is complex and provides
significant overhead.
With this pull request, users can access the metrics of all cloud resources
modeled by OpenDC via methods such as `getSchedulerStats()`, etc.
** Breaking Changes **
- `ComputeService.hostCount` removed in favour of `ComputeService.hosts.size`
|
|
This change updates the `TFDevice` interface to directly expose
statistics about the accelerator device to the user. Previously, the
user had to access these values through OpenTelemetry, which required
substantial extra work.
|
|
This change updates the `FaaSService` interface to directly expose
statistics about the scheduler and individual functions to the user, such
that they do not necessarily have to interact with OpenTelemetry to obtain
these values.
|
|
This change updates the `WorkflowService` interface to directly expose
statistics about the scheduler to the user, such that they do not
necessarily have to interact with OpenTelemetry to obtain these values
|
|
This change introduces a `ComputeMetricReader` class that can be used as
a replacement for the `CoroutineMetricReader` class when reading metrics
from the Compute service. This implementation operates directly on a
`ComputeService` instance, providing better performance.
