From 6a2a5423479696e8dc28885be27cc3e3252f28b0 Mon Sep 17 00:00:00 2001 From: Fabian Mastenbroek Date: Wed, 30 Dec 2020 14:03:12 +0100 Subject: simulator: Add generic framework for resource consumption modeling This change adds a generic framework for modeling resource consumptions and adapts opendc-simulator-compute to model machines and VMs on top of this framework. This framework anticipates the addition of additional resource types such as memory, disk and network to the OpenDC codebase. --- .../src/main/kotlin/org/opendc/compute/simulator/SimHost.kt | 4 ++-- .../test/kotlin/org/opendc/compute/simulator/SimHostTest.kt | 12 ++++++------ 2 files changed, 8 insertions(+), 8 deletions(-) (limited to 'simulator/opendc-compute') diff --git a/simulator/opendc-compute/opendc-compute-simulator/src/main/kotlin/org/opendc/compute/simulator/SimHost.kt b/simulator/opendc-compute/opendc-compute-simulator/src/main/kotlin/org/opendc/compute/simulator/SimHost.kt index 19fa3e97..0da81152 100644 --- a/simulator/opendc-compute/opendc-compute-simulator/src/main/kotlin/org/opendc/compute/simulator/SimHost.kt +++ b/simulator/opendc-compute/opendc-compute-simulator/src/main/kotlin/org/opendc/compute/simulator/SimHost.kt @@ -35,7 +35,7 @@ import org.opendc.compute.simulator.power.models.ConstantPowerModel import org.opendc.simulator.compute.* import org.opendc.simulator.compute.interference.IMAGE_PERF_INTERFERENCE_MODEL import org.opendc.simulator.compute.interference.PerformanceInterferenceModel -import org.opendc.simulator.compute.model.MemoryUnit +import org.opendc.simulator.compute.model.SimMemoryUnit import org.opendc.simulator.failures.FailureDomain import org.opendc.utils.flow.EventFlow import java.time.Clock @@ -216,7 +216,7 @@ public class SimHost( val originalCpu = machine.model.cpus[0] val processingNode = originalCpu.node.copy(coreCount = cpuCount) val processingUnits = (0 until cpuCount).map { originalCpu.copy(id = it, node = processingNode) } - val memoryUnits = listOf(MemoryUnit("Generic", "Generic", 3200.0, memorySize)) + val memoryUnits = listOf(SimMemoryUnit("Generic", "Generic", 3200.0, memorySize)) return SimMachineModel(processingUnits, memoryUnits) } 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 e1a1d87e..a45ab9fc 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 @@ -40,9 +40,9 @@ import org.opendc.compute.api.ServerWatcher import org.opendc.compute.service.driver.HostEvent import org.opendc.simulator.compute.SimFairShareHypervisorProvider import org.opendc.simulator.compute.SimMachineModel -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.model.SimMemoryUnit +import org.opendc.simulator.compute.model.SimProcessingNode +import org.opendc.simulator.compute.model.SimProcessingUnit import org.opendc.simulator.compute.workload.SimTraceWorkload import org.opendc.simulator.utils.DelayControllerClockAdapter import java.time.Clock @@ -62,11 +62,11 @@ internal class SimHostTest { scope = TestCoroutineScope() clock = DelayControllerClockAdapter(scope) - val cpuNode = ProcessingNode("Intel", "Xeon", "amd64", 2) + val cpuNode = SimProcessingNode("Intel", "Xeon", "amd64", 2) machineModel = SimMachineModel( - cpus = List(cpuNode.coreCount) { ProcessingUnit(cpuNode, it, 3200.0) }, - memory = List(4) { MemoryUnit("Crucial", "MTA18ASF4G72AZ-3G2B1", 3200.0, 32_000) } + cpus = List(cpuNode.coreCount) { SimProcessingUnit(cpuNode, it, 3200.0) }, + memory = List(4) { SimMemoryUnit("Crucial", "MTA18ASF4G72AZ-3G2B1", 3200.0, 32_000) } ) } -- cgit v1.2.3
