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/test/kotlin/org/opendc/compute/service/ComputeServiceTest.kt | 2 +- .../src/test/kotlin/org/opendc/compute/simulator/SimHostTest.kt | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'simulator/opendc-compute') diff --git a/simulator/opendc-compute/opendc-compute-service/src/test/kotlin/org/opendc/compute/service/ComputeServiceTest.kt b/simulator/opendc-compute/opendc-compute-service/src/test/kotlin/org/opendc/compute/service/ComputeServiceTest.kt index c6e24346..059f9cd9 100644 --- a/simulator/opendc-compute/opendc-compute-service/src/test/kotlin/org/opendc/compute/service/ComputeServiceTest.kt +++ b/simulator/opendc-compute/opendc-compute-service/src/test/kotlin/org/opendc/compute/service/ComputeServiceTest.kt @@ -43,7 +43,7 @@ import org.opendc.compute.service.scheduler.FilterScheduler import org.opendc.compute.service.scheduler.filters.ComputeCapabilitiesFilter import org.opendc.compute.service.scheduler.filters.ComputeFilter import org.opendc.compute.service.scheduler.weights.MemoryWeigher -import org.opendc.simulator.utils.DelayControllerClockAdapter +import org.opendc.simulator.core.DelayControllerClockAdapter import java.util.* /** diff --git a/simulator/opendc-compute/opendc-compute-simulator/src/test/kotlin/org/opendc/compute/simulator/SimHostTest.kt b/simulator/opendc-compute/opendc-compute-simulator/src/test/kotlin/org/opendc/compute/simulator/SimHostTest.kt index 2a897b28..cdbdd58b 100644 --- a/simulator/opendc-compute/opendc-compute-simulator/src/test/kotlin/org/opendc/compute/simulator/SimHostTest.kt +++ b/simulator/opendc-compute/opendc-compute-simulator/src/test/kotlin/org/opendc/compute/simulator/SimHostTest.kt @@ -47,7 +47,7 @@ import org.opendc.simulator.compute.model.MemoryUnit import org.opendc.simulator.compute.model.ProcessingNode import org.opendc.simulator.compute.model.ProcessingUnit import org.opendc.simulator.compute.workload.SimTraceWorkload -import org.opendc.simulator.utils.DelayControllerClockAdapter +import org.opendc.simulator.core.DelayControllerClockAdapter import org.opendc.telemetry.sdk.metrics.export.CoroutineMetricReader import org.opendc.telemetry.sdk.toOtelClock import java.util.UUID -- cgit v1.2.3
