2021-05-07build: Use Gradle version catalogFabian Mastenbroek
This pull request updates the Gradle build configuration to use the new version catalog functionality, which allows us to store our dependency versions in a centralized file located at `gradle/libs.versions.toml`. Our previous approach stored the versions in `gradle.properties`. The benefit of this approach however is that (1) it will be supported by Gradle and (2) it allows us to access dependencies safely.
2021-05-07build: Access version catalog from buildSrcFabian Mastenbroek
This change adds a workaround to the build configuration so that we can access the version catalog from pre-compiled scripts in buildSrc. In this way, we can use the version catalog everywhere. This workaround is necessary until https://github.com/gradle/gradle/issues/15383 is fixed.
2021-05-07build: Use Gradle version catalogFabian Mastenbroek
This change adds support for the Gradle version catalog feature in our build configuration. This allows us to have a single file, gradle/libs.versions.toml, which contains all the dependency versions used in this project.

2021-05-06build: Increase metaspace budgetFabian Mastenbroek
This change increases the max metaspace size that Gradle/Dokka is allowed to use. We unfortunately need this workaround for Dokka to properly build the documentation during the release workflow.

2021-05-05harness: Improve OpenDC Experiment Harness (v1) Fabian Mastenbroek
This pull request contains several improvements to the OpenDC Experiment Harness, which aims to improve user-experience of users when re-running experiments in the repository. * Split the harness into separate modules * Add support for adding additional classpath entries when running experiments via the console * Initial support for configuration of experiments using HOCON.
2021-05-05harness: Add ability to specify custom configuration from CLIFabian Mastenbroek
This change updates the command line interface of the OpenDC Experiment Harness to include an option for specifying a custom configuration file.
2021-05-05exp: Include experiments in main distributionFabian Mastenbroek
This change updates the Gradle configuration to include experiments in the main distribution of OpenDC. Users can directly execute the experiments from the command-line without having to recompile the entire code-base.
2021-05-05exp: Add support for experiment configurationFabian Mastenbroek
This change adds support for configuring the experiments via configuration files using the TypeSafe config library. In the future, we will also integrate support for configuration into the harness.
2021-05-05harness: Extend Harness CLI with classpath optionsFabian Mastenbroek
This change adds support for appending libraries to the classpath when searching for experiments to run using the OpenDC Harness command line interface.
2021-05-05harness: Split harness into separate modulesFabian Mastenbroek
This change splits the OpenDC Experiment Harness into separate modules. This prevents users from pulling in unnecessary dependencies when depending on the harness API.
2021-05-04exp: Fix power draw reportingFabian Mastenbroek
This pull request fixes an issue with the power draw reporting in experiments. Previously, when the power draw of a machine did not change in subsequent metric collection cycles, the power draw would be reported as zero. * Update power draw as soon as the machine is started. * Use OpenTelemetry view to aggregate based on the power draw's last reported value.
2021-05-04exp: Fix aggregation of power drawFabian Mastenbroek
This change fixes the aggregation of the power draw metric. Previously, if the power draw did not change between collection cycles, the power draw would be reported as zero. This change uses OpenTelemetry Views to collect the latest value of the power draw each cycle.
2021-05-04simulator: Update power draw on machine drawFabian Mastenbroek
This change fixes an issue where the power draw of a machine is initially zero and does not update until the CPU usage is higher than zero, while the idle power is the machine is not actually zero.
2021-05-03simulator: Add support for central resource scheduling (#126)Fabian Mastenbroek
This pull request adds support for central resource scheduling. This enables possible optimizations in the future where we can efficiently schedule resource updates. * Introduce `SimResourceScheduler` which centralizes the logic for scheduling resource interrupts. * Fix benchmarks * Add generic approach for reporting resource events * Simplify scheduling logic of resource aggregator. **Breaking API Changes** * Classes in `opendc-simulator-resources` now take `SimResourceScheduler` as opposed to a `CoroutineContext` and `Clock`.
2021-05-03simulator: Introduce SimResourceSchedulerFabian Mastenbroek
This change introduces the SimResourceScheduler interface, which is a generic interface for scheduling the coordination and synchronization between resource providers and resource consumers. This interface replaces the need for users to manually specify the clock and coroutine context per resource provider.
