From 1c0568c31d60d4e690b4b9aec2e14f660b72a5c8 Mon Sep 17 00:00:00 2001 From: Fabian Mastenbroek Date: Wed, 21 Apr 2021 14:30:55 +0200 Subject: simulator: Introduce SimulationCoroutineDispatcher This change introduces the SimulationCoroutineDispatcher implementation which replaces the TestCoroutineDispatcher for running single-threaded simulations. Previously, we used the TestCoroutineDispatcher from the kotlinx-coroutines-test modules for running simulations. However, this module is aimed at coroutine tests and not at simulations. In particular, having to construct a Clock object each time for the TestCoroutineDispatcher caused a lot of unnecessary lines. With the new approach, the SimulationCoroutineDispatcher automatically exposes a usable Clock object. In addition to ergonomic benefits, the SimulationCoroutineDispatcher is much faster than the TestCoroutineDispatcher due to the assumption that simulations run in only a single thread. As a result, the dispatcher does not need to perform synchronization and can use the fast PriorityQueue implementation. --- .../src/main/kotlin/org/opendc/experiments/capelin/Portfolio.kt | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'simulator/opendc-experiments/opendc-experiments-capelin/src/main') diff --git a/simulator/opendc-experiments/opendc-experiments-capelin/src/main/kotlin/org/opendc/experiments/capelin/Portfolio.kt b/simulator/opendc-experiments/opendc-experiments-capelin/src/main/kotlin/org/opendc/experiments/capelin/Portfolio.kt index 941d3c97..ee048cb0 100644 --- a/simulator/opendc-experiments/opendc-experiments-capelin/src/main/kotlin/org/opendc/experiments/capelin/Portfolio.kt +++ b/simulator/opendc-experiments/opendc-experiments-capelin/src/main/kotlin/org/opendc/experiments/capelin/Portfolio.kt @@ -45,7 +45,7 @@ import org.opendc.format.environment.sc20.Sc20ClusterEnvironmentReader import org.opendc.format.trace.PerformanceInterferenceModelReader import org.opendc.harness.dsl.Experiment import org.opendc.harness.dsl.anyOf -import org.opendc.simulator.utils.DelayControllerClockAdapter +import org.opendc.simulator.core.DelayControllerClockAdapter import org.opendc.telemetry.sdk.toOtelClock import java.io.File import java.util.* -- cgit v1.2.3
