2022-02-18fix(simulator): Flush results before accessing countersFabian Mastenbroek
This change updates the simulator implementation to flush the active progress when accessing the hypervisor counters. Previously, if the counters were accessed, while the mux or consumer was in progress, its counter values were not accurate.
2022-02-18fix(telemetry): Fix reporting of CPU timeFabian Mastenbroek
This change fixes an issue with the CPU time aggregation for VMs in the ComputeMetricAggregator, leading to incorrect values.
2022-02-18bug(trace): Adjust CPU capacity to number of vCPUsFabian Mastenbroek
This change fixes an issue where the number of vCPUs was not taken into account when converting from CPU Usage percentage to MHz.
2022-02-18merge: Address technical debt in codebaseFabian Mastenbroek
This pull request removes some of the existing technical debt in the OpenDC codebase. Close #51 ## Implementation Notes :hammer_and_pick: * Add Pacer to pace scheduling cycles. * Rename utils module to common module * Optimize TimerScheduler * Remove opendc-platform module * Disallow duplicate UIDs for SimHost ## Breaking API Changes :warning: * TimerScheduler does not implement `AutoCloseable` anymore.
2022-02-18fix(compute): Disallow duplicate UIDs for SimHostFabian Mastenbroek
This change fixes an issue with the ComputeServiceHelper where it allowed users to register multiple SimHost objects with the same UID. See this issue for more information: https://github.com/atlarge-research/opendc/issues/51
2022-02-18build: Remove opendc-platform moduleFabian Mastenbroek
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.
2022-02-18perf(common): Optimize TimerSchedulerFabian Mastenbroek
This change updates the TimerScheduler implementation to directly use the Delay object instead of running the timers inside a coroutine. Constructing the coroutine is more expensive, so we prefer running in a Runnable.
2022-02-18refactor(utils): Rename utils module to common moduleFabian Mastenbroek
This change adds a new module, opendc-common, that contains functionality that is shared across OpenDC's modules. We move the existing utils module into this new module.
2022-02-18feat(utils): Add Pacer to pace scheduling cyclesFabian Mastenbroek
This change adds a new Pacer class that can pace the incoming scheduling requests into scheduling cycles by allowing the user to specify a scheduling quantum.
2022-02-18build: Update to Gradle 7.4Fabian Mastenbroek
This change updates the Gradle wrapper to version 7.4.

2022-02-17fix(web/ui): Fix creation of topologiesFabian Mastenbroek
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.

2022-02-17ci: Fix API deployment using Docker ComposeFabian Mastenbroek
This change updates the Docker Compose configuration to properly deploy the API server, by passing the necessary Auth0 information to it.
2022-02-17fix(web/runner): Support custom audience in web runnerFabian Mastenbroek
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.
2022-02-15refactor: Update OpenTelemetry to version 1.11Fabian Mastenbroek
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.

2021-12-12fix(trace): Read dependencies from .gwf trace file (#50)Florian Gerlinghoff
Tasks from a .gwf trace file did not have dependencies because this property was not assigned after being read in the GwfTaskTableReader. I removed the conversion from String to Long in parseParents because it seems like other readers (the Parquet reader in particular) return Strings as well, which is why they are converted to Long in line 75 of TraceHelpers.kt.

2021-12-11build: Update to log4j 2.15.0Fabian Mastenbroek
This change addresses the RCE vulnerability in log4j <= 2.14.1.
2021-12-09merge: Support convergence of space shared hypervisorFabian Mastenbroek
This change addresses an issue with the SimSpaceSharedHypervisor implementation where it did not emit convergence events due to missing implementation. This caused issues with users of this class trying to obtain usage data, which depended on these events being emitted. * Support `FlowConvergenceListener` in `FlowForwarder` and `ForwardingFlowMux` * Support `FlowConvergenceListener` in `SimSpaceSharedHypervisor`. ## Breaking API Changes :warning: * N/A

2021-12-01bug(workflow): Activate timer even without incoming jobsFabian Mastenbroek
This change fixes an issue where a scheduling cycle is not scheduled when there are no incoming jobs. Still, there might be pending tasks that can be scheduled. Therefore, we remove this conditional.

2021-11-17merge: Improve workflow service (#43)Fabian Mastenbroek
This pull request is the first in a series of changes to the workflow service. This pull request aims to help users setup workflow simulations. The next pull requests will focus on improving the design of the workflow service. * Remove WorkflowSchedulerMode * Add helper tools for workflow simulations (e.g. `WorkflowServiceHelper`) **Breaking API Changes** * Removal of `WorkflowSchedulerMode` * Rename from `ComputeWorkloadRunner` to `ComputeServiceHelper`
2021-11-17refactor(workflow): Remove WorkflowSchedulerModeFabian Mastenbroek
This change removes the WorkflowSchedulerMode interface in favour of an integrated timer scheduler approach that batches scheduling cycles over a user-specified quantum. This quantum can be lowered to a small value to get the interactive behavior. There is no replacement for the random behavior, but we believe that such a policy makes no sense in a real-world scenario.
2021-11-16feat(workflow): Add helper tools for workflow simulationsFabian Mastenbroek
This change adds a new module, opendc-workflow-workload that contains helper code for constructing workflow simulations using OpenDC.
2021-11-11merge: Upgrade to Gradle 7.3 (#42)Fabian Mastenbroek
