2022-09-22refactor(compute): Pass failure model during workload evaluationFabian Mastenbroek
This change updates the `ComputeServiceHelper` class to provide the failure model via a parameter to the `run` method instead of constructor parameter. This separates the construction of the topology from the simulation of the workload.
2022-09-22refactor(sim/compute): Simplify SimHypervisor classFabian Mastenbroek
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.
2022-09-22refactor(sim/compute): Make interference domain independent of profileFabian Mastenbroek
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.
2022-09-22refactor(compute): Simplify constructor of SimHostFabian Mastenbroek
This change updates the constructor of SimHost to receive a `SimBareMetalMachine` and `SimHypervisor` directly instead of construction these objects itself. This ensures better testability and also simplifies the constructor of this class, especially when future changes to `SimBareMetalMachine` or `SimHypervisor` change their constructors.
2022-09-22refactor(compute): Add separate error host stateFabian Mastenbroek
This change adds a new HostState to indicate that the host is in an error state as opposed to being purposefully unavailable.
2022-09-22refactor(sim/compute): Extract Random dependency from interference modelFabian Mastenbroek
This change moves the Random dependency outside the interference model, to allow the interference model to be completely immutable and passable between different simulations.
2022-09-21perf(sim/compute): Prevent boxing in interference algorithmFabian Mastenbroek
This change updates the performance interference algorithm to remove the boxing that happened due to using a generic collection for storing integers. This collection was accessed in the algorithm's hot path, so could cause slowdown.
2022-09-21refactor(sim/compute): Move interference logic into VmInterferenceMemberFabian Mastenbroek
This change updates the design of the VM interference model, where we move more of the logic into the `VmInterferenceMember` interface. This removes the dependency on the `VmInterferenceModel` for the hypervisor interface.
2022-09-21refactor(sim/compute): Pass interference key via parameterFabian Mastenbroek
This change updates the signature of the `SimHypervisor` interface to accept a `VmInterferenceKey` when creating a new virtual machine, instead of providing a string identifier. This is in preparation for removing the dependency on the `VmInterferenceModel` in the `SimAbstractHypervisor` class.
2022-09-21refactor(sim/compute): Remove timestamp parameter from SimTraceFabian Mastenbroek
This change removes the timestamp parameter from `SimTrace`. Instead, it is now assumed that the trace is continuous and the end of a fragment starts a new fragment, in order to simplify replaying of the trace.
2022-09-21refactor(sim/compute): Remove FlowEngine from SimMachineContextFabian Mastenbroek
This change removes the reference to the active FlowEngine from the SimMachineContext interface. This prevents leaking the lower layer into this module.
2022-09-21refactor(sim/compute): Remove convergence listener parameterFabian Mastenbroek
This change removes the convergence listener parameter in for the `SimBareMetalMachine` and the hypervisors. This parameter was not used in the code-base and is being removed with the introduction of the new flow2 module.
2022-09-21refactor(sim/compute): Move VM interference model into compute simulatorFabian Mastenbroek
This change moves the core of the VM interference model from the flow module into the compute simulator. This logic can be contained in the compute simulator and does not need to leak into the flow-level simulator.
2022-09-21feat(compute): Add support for affinity scheduling (#101)Fabian Mastenbroek
This change adds support for (anti-)affinity scheduling of servers onto hosts, which happens at the compute service level. In the future, we might add support for server groups, which also enables soft (anti-)affinity scheduling. Implements #26 ## Implementation Notes :hammer_and_pick: * Add `DifferentHostFilter` to schedule instances on different hosts from a set of instances. * Add `SameHostFilter` to schedule instances on the same hosts as a set of instances.
2022-09-20merge: Improve web interface (#100)Fabian Mastenbroek
This pull request addresses several issues with the current web interface. ## Implementation Notes :hammer_and_pick: * Update dependencies of web UI where possible * Fix deletion of topology * Fix duplication of topology * Only display selected metrics * Use correct color for login button * Fix z-index of context selector * Move project selector into masthead * Reduce height of application header * Redesign projects page * Use PatternFly Charts for plots * Do not fail on stale Redux state * Fix overflow of topology sidebar * Fix deletion of portfolios * Migrate to composable table ## External Dependencies :four_leaf_clover: * `classnames` has been replaced by `clsx` * PatternFly Charts have replaced the use of `recharts`
2022-09-20refactor(web/ui): Migrate to composable tableFabian Mastenbroek
This change updates the web interface to use the composable table API offered by PatternFly 4. This has replaced the legacy table API which will be removed in the next major version of PatternFly.
2022-09-20fix(web/server): Fix deletion of portfoliosFabian Mastenbroek
This change fixes an issue where the deletion of portfolios would fail due to no transaction context being active.
2022-09-20fix(web/ui): Fix overflow of topology sidebarFabian Mastenbroek
This change fixes an issue with the web interface where the sidebar would overflow due to the large number of rack slots that are displayed in the sidebar.
2022-09-20fix(web/ui): Do not fail on stale Redux stateFabian Mastenbroek
This change fixes an issue where switching between different topologies would fail due to stale Redux state. We have updated the components to take into account that ids may not exist in the Redux store.
2022-09-20refactor(web/ui): Use PatternFly Charts for plotsFabian Mastenbroek
This change updates the OpenDC web interface to use the PatternFly Charts package to render the results of a portfolio. Previously, we used Recharts, but this package does not support SSR, whereas the PatternFly Charts package matches our design framework.
2022-09-20feat(web/ui): Redesign projects pageFabian Mastenbroek
This change updates the design of the projects page to use a gallery overview.
2022-09-20feat(web/ui): Reduce height of application headerFabian Mastenbroek
This change reduces the height of the application header to 3.5rem to increase the screen real-estate that we can use for the application content.
2022-09-20refactor(web/ui): Move project selector into mastheadFabian Mastenbroek
This change moves the project selector into the masthead since it affects the whole application. This follows the PatternFly guidelines.
2022-09-20fix(web/ui): Fix z-index of context selector componentFabian Mastenbroek
This change addresses an issue with the context selector component where the dropdown would fall behind a sticky tab bar in the main content.
2022-09-20fix(site): Use correct color for login buttonFabian Mastenbroek
2022-09-20build(web/ui): Use clsx instead of classnamesFabian Mastenbroek
This change replaces the classnames dependency for the clsx dependency, which uses less code and is in general faster than the classnames dependency.
2022-09-20fix(web/ui): Only display selected metricsFabian Mastenbroek
This change fixes an issue with the web interface where all available metrics were shown to the user, instead of the metrics belonging to the portfolio.
2022-09-20fix(web/ui): Fix duplication of topologyFabian Mastenbroek
This change addresses an issue where a new topology did not correctly clone an existing topology.
2022-09-20fix(web/ui): Fix deletion of topologyFabian Mastenbroek
This change fixes an issue with the OpenDC web interface where the user cannot remove an existing topology from the topology table due to a programming mistake.
2022-09-20build(web/ui): Update dependenciesFabian Mastenbroek
This change updates the dependencies of the OpenDC web interface were possible. We remain on React 17 until PatternFly adds support for the new React version.

2022-08-03merge: Update build and runtime dependencies (#94)Fabian Mastenbroek
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 to Gradle 7.5 * Update simulator dependency versions * Fix Docker deployment ## Breaking API Changes :warning: * N/A
2022-08-03build(web/server): Include sample traces in distributionFabian Mastenbroek
This change updates the build script of the OpenDC web server to include the sample traces in the repository.
2022-08-03fix(web/server): Remove unused Auth0 runner configurationFabian Mastenbroek
This change removes the unused Auth0 runner configuration from the Docker Compose configuration. Currently, it is marked as required, so Docker Compose will fail if these values are not specified.
2022-08-03fix(web/server): Customize Auth0 settings during build timeFabian Mastenbroek
This change fixes the Dockerfile for the OpenDC web server by also providing the custom Auth0 configuration values during build time of the image. These settings cannot be changed during runtime, so we need to declare them in the Dockerfile.
2022-08-03build: Update simulator dependenciesFabian Mastenbroek
This change updates the simulator dependencies to the latest available version where possible.
2022-08-03build: Update to Gradle 7.5Fabian Mastenbroek
This change updates the build system Gradle to version 7.5, which ships Kotlin 1.6.21. That is the same version currently used by OpenDC and should reduce the warning messages produced by Gradle due to version mismatches.
2022-08-03merge: Simplify OpenDC deployment processFabian Mastenbroek
This pull request attempts to simplify the deployment process necessary for deploying OpenDC locally or using Docker. There was currently not a clear and simple way to deploy OpenDC locally, yet the Docker-based deployment was also out-of-sync. ## Implementation Notes :hammer_and_pick: * Address several bugs in the OpenDC web runner * Fix dependency related issues * Rename `opendc-web-api` to `opendc-web-server` * Create a local distribution of `opendc-web-server`. * Fix Docker deployment * Update deployment guide ## External Dependencies :four_leaf_clover: * Quarkus 2.11.1 * `jandex-gradle-plugin` 0.13.2 ## Breaking API Changes :warning: * `TraceFormat.installedProviders` has been changed to `TraceFormat.getInstalledProviders`. The list of installed providers is now not cached at first access, but queried every time the method is invoked and its results depend on the caller context (e.g., context class loader). * `OpenDCRunner` now requires a `JobManager` as constructor argument, which can be constructed as follows: `JobManager.create(client)` * `opendc-web-api` is now renamed to `opendc-web-server`.
2022-08-03docs: Update deployment guideFabian Mastenbroek
This change updates the deployment guide based on the latest changes to the Quarkus application. Quite a few existing configuration options can be removed now.
2022-08-03ci: Build Docker image for OpenDC web UIFabian Mastenbroek
This change adds a build step for building the OpenDC web UI as Docker image. We forgot this step and found that the image failed to build during previous commits.
2022-08-03fix(web/ui): Fix Docker deploymentFabian Mastenbroek
This change fixes the Docker deployment of the OpenDC web UI. There have been several updates to the build process of the web UI, which have not taken into account the Docker deployment process. This change addresses these discrepancies.
2022-08-03feat(web/server): Implement database migrations using FlywayFabian Mastenbroek
This change updates the Quarkus-based web server to use Flyway for migrating between schema versions. This enables us to evolve the schema and denote it in SQL.
