This change fixes an issue in SimHost where guests that where inactive were also failed, causing an IllegalStateException.
2021-09-07fix(compute): Use correct memory size for host memoryFabian Mastenbroek
This change fixes an issue where all servers could not be scheduled due to the memory size of the host being computed incorrectly.

2021-09-02refactor(format): Remove environment reader from format libraryFabian Mastenbroek
This change removes the environment reader from the format library since they are highly specific for the particular experiment. In the future, we hope to have a single format to setup the entire datacenter (perhaps similar to the format used by the web runner).
2021-09-02refactor(trace): Extract Parquet helpers into separate moduleFabian Mastenbroek
This change extracts the Parquet helpers outside format module into a new module, in order to improve re-usability of these helpers.

2021-08-25merge: Measure power draw in SimHost without PSU overheadFabian Mastenbroek
This pull request implements power draw reporting in SimHost where the power draw is computed without PSU overhead. * Remove usage and speed fields from SimMachine * Measure power draw without PSU overhead **Breaking API Changes** * `SimMachine.usage` and `SimMachine.speed` fields are removed.
2021-08-25refactor(compute): Measure power draw without PSU overheadFabian Mastenbroek
This change updates the SimHost implementation to measure the power draw of the machine without PSU overhead to make the results more realistic.
2021-08-25refactor(simulator): Remove usage and speed fields from SimMachineFabian Mastenbroek
This change removes the usage and speed fields from SimMachine. We currently use other ways to capture the usage and speed and these fields cause an additional maintenance burden and performance impact. Hence the removal of these fields.

This pull request updates to OpenTelemetry version 1.5.0. * Update dependency to OpenTelemetry 1.5 * Fix breaking changes in metrics API * Eliminate unnecessary double to long conversions * Simplify metric extraction for monitor
2021-08-25refactor(capelin): Simplify metric extraction for monitorFabian Mastenbroek
This change updates the metric exporter logic in the Capelin module and reduces the number of allocations by looping directly over the collection of metrics.
2021-08-25fix(capelin): Eliminate unnecessary double to long conversionsFabian Mastenbroek
This change eliminates the unnecessary conversions from double to long in the Capelin metric processing code.
2021-08-25fix(simulator): Eliminate unnecessary double to long conversionsFabian Mastenbroek
This change eliminates unnecessary double to long conversions in the simulator. Previously, we used longs to denote the amount of work. However, in the mean time we have switched to doubles in the lower stack.
2021-08-25build: Upgrade to OpenTelemetry 1.5Fabian Mastenbroek
This change upgrades the OpenTelemetry dependency to version 1.5, which contains various breaking changes in the metrics API.
2021-08-24merge: Add tests for interference and failures in CapelinFabian Mastenbroek

This allows us to track regressions in these subsystems more easily. * Clean up Bitbrains trace reader to enable re-use * Keep trace order after sampling * Update Bitbrains trace tests * Add support for reporting interfered work * Add support for SimHost failure * Add tests for interference and failures
2021-08-24test(capelin): Add tests for interference and failuresFabian Mastenbroek
This change adds tests to the Capelin integration suite for performance interference as well as failures. These test more accurately the experiment setup.
2021-08-24feat(compute): Add support for SimHost failureFabian Mastenbroek
This change adds support for failures in the SimHost implementation. Failing a host will now cause the virtual machine to enter an error state.
2021-08-24feat(simulator): Add support for reporting interfered workFabian Mastenbroek
This change adds support to the simulator for reporting the work lost due to performance interference.
2021-08-24fix(capelin): Update Bitbrains trace testsFabian Mastenbroek
This change updates the Bitbrains trace tests with the updated trace that does not hardcode the duration of the trace fragments.
2021-08-24fix(capelin): Keep trace order after samplingFabian Mastenbroek
This change fixes an issue with the workload sampler where the resulting workload entries would not be ordered properly according to their submission time.
2021-08-24refactor(format): Clean up Bitbrains trace reader to enable re-useFabian Mastenbroek
This change updates the code for the Bitbrains trace reader and upgrades the TraceConverter to re-use existing code of the Bitbrains trace reader.
2021-08-24merge: Execute trace fragments based on timestampsFabian Mastenbroek
This pull request updates the simulator to execute workload traces based on the fragment's timestamps. This means that traces will execute their timestamps at the correct time. * Execute traces based on timestamps * Record overcommit only after deadline exceeded * Support trace fragments with zero cores available * Support unaligned trace fragments **Breaking API Changes** * `SimTraceWorkload.Fragment` now requires a `timestamp` parameter.
