From 9e5e830e15b74f040708e98c09ea41cd96d13871 Mon Sep 17 00:00:00 2001 From: Fabian Mastenbroek Date: Thu, 27 May 2021 16:34:06 +0200 Subject: simulator: Centralize resource logic in SimResourceInterpreter This change introduces the SimResourceInterpreter which centralizes the logic for scheduling and interpreting the communication between resource consumer and provider. This approach offers better performance due to avoiding invalidating the state of the resource context when not necessary. Benchmarks show in the best case a 5x performance improvement and at worst a 2x improvement. --- .../main/kotlin/org/opendc/serverless/simulator/SimFunctionDeployer.kt | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'opendc-serverless/opendc-serverless-simulator/src/main/kotlin') diff --git a/opendc-serverless/opendc-serverless-simulator/src/main/kotlin/org/opendc/serverless/simulator/SimFunctionDeployer.kt b/opendc-serverless/opendc-serverless-simulator/src/main/kotlin/org/opendc/serverless/simulator/SimFunctionDeployer.kt index b5516b4d..1871bb04 100644 --- a/opendc-serverless/opendc-serverless-simulator/src/main/kotlin/org/opendc/serverless/simulator/SimFunctionDeployer.kt +++ b/opendc-serverless/opendc-serverless-simulator/src/main/kotlin/org/opendc/serverless/simulator/SimFunctionDeployer.kt @@ -37,6 +37,7 @@ import org.opendc.simulator.compute.SimMachineModel import org.opendc.simulator.compute.cpufreq.PerformanceScalingGovernor import org.opendc.simulator.compute.cpufreq.SimpleScalingDriver import org.opendc.simulator.compute.power.ConstantPowerModel +import org.opendc.simulator.resources.SimResourceInterpreter import java.time.Clock import java.util.ArrayDeque import kotlin.coroutines.Continuation @@ -72,7 +73,7 @@ public class SimFunctionDeployer( /** * The machine that will execute the workloads. */ - public val machine: SimMachine = SimBareMetalMachine(scope.coroutineContext, clock, model, PerformanceScalingGovernor(), SimpleScalingDriver(ConstantPowerModel(0.0))) + public val machine: SimMachine = SimBareMetalMachine(SimResourceInterpreter(scope.coroutineContext, clock), model, PerformanceScalingGovernor(), SimpleScalingDriver(ConstantPowerModel(0.0))) /** * The job associated with the lifecycle of the instance. -- cgit v1.2.3
