云计算仿真工具cloudsim 3.0.3 【无错误，带例子！】

------------------------------------------- Changes from CloudSim 3.0.2 to CloudSim 3.0.3 ------------------------------------------- WHAT'S NEW ---------- This is a bug fix and refactoring release. The following updates have been made: - Removed the dependency on the flanagan library. It is now replaced with Apache Math. The implementation and interface of the MathUtil has been changed accordingly. - The minimal time between events is now configurable. - Fixed Issue 44 : UtilizationModelPlanetLabInMemory: use a global constant to define the size of the data field: a new constructor for the classes, allowing definition of data size, was added. - Fixed Issue 49 : Wrong calculation of debt during migrationL: all references to debt from Datacenter and its subclasses were removed. ------------------------------------------- Changes from CloudSim 3.0.1 to CloudSim 3.0.2 ------------------------------------------- WHAT'S NEW ---------- This is a bug fix release. The following updates have been made: - Fixed Issue 32: a problem with the ant classpath declaration - Fixed Issue 37: recalculating MIPS in PowerVmAllocationPolicyMigrationAbstract.findHostForVm() - Updated the references to the CCPE paper ------------------------------------------- Changes from CloudSim 3.0 to CloudSim 3.0.1 ------------------------------------------- WHAT'S NEW ---------- This is mainly a bug fix release. The following updates have been made: - Made the CloudletSchedulerTimeShared.getCapacity method protected, to facilitate the development of new cloudlet schedulers. - Fixed in PeList: problem in the generics declaration. - Fixed Issue #40: Inconsistencies on the return of Cloudlet.isCloudletFinished() and the Cloudlet status. - Fixed Issue #35: Default behaviour of Cloudlet may lead to unnecessary usage of heap space. - Fixed bug when searching for Cloudlets to cancel in cloudletSchedulerTimeshared - Fixed Issue #34: Call getVm(vmId, userId) Function had swaped parameters in several parts of the Datacenter class. - Fixed misleading comment on Example 4 that said that capacity of created VMs were different. - Fixed comment on example 2, which said that MIPS requirements were different. Actually, they are the same. - Fixed the ant building problem: added Flanagan's library to the classpath; updated the readme.txt ----------------------------------------- Changes from CloudSim 2.1 to CloudSim 3.0 ----------------------------------------- WHAT'S NEW ---------- - NEW VM SCHEDULER. VmSchedulerTimeSharedOverSubscription models a scheduler that allows unbounded number of VMS to be deployed in a single Host, regardless its requirements in terms of number of MIPS. Notice that this was the behaviour of VmSchedulerTimeShared in CloudSim 1.0 Beta, but this behaviour had changed in CloudSim 2.0 to accommodate requests with specific amount of MIPS. - NEW DATACENTER NETWORK MODEL. A internal network model has been added to CloudSim 3.0. It supports definition of switches connecting hosts in arbitrary network topologies. New Vm classes and Cloudlet classes were added to take advantage of this feature without breaking compatibility of older code. This new feature also enables modelling of message-passing applications. They are included in the package 'network.datacenter'. - NEW VM ALLOCATION AND SELECTION POLICIES. 6 new VM allocation and 4 VM selection policies were added to the power package. To find more details about the policies please refer to the following paper: Anton Beloglazov, and Rajkumar Buyya, "Optimal Online Deterministic Algorithms and Adaptive Heuristics for Energy and Performance Efficient Dynamic Consolidation of Virtual Machines in Cloud Data Centers", Concurrency and Computation: Practice and Experience, ISSN: 1532-0626, Wiley Press, New York, USA, 2011, DOI: 10.1002/cpe.1867 - NEW POWER MODELS. 7 power models of real servers using the data from SPECpower were added to the power package. They are PowerModelSpecPowerHpProLiantMl110G3PentiumD930, PowerModelSpecPowerHpProLiantMl110G4Xeon3040, PowerModelSpecPowerHpProLiantMl110G5Xeon3075, PowerModelSpecPowerIbmX3250XeonX3470, PowerModelSpecPowerIbmX3250XeonX3480, PowerModelSpecPowerIbmX3550XeonX5670, and PowerModelSpecPowerIbmX3550XeonX5675. - NEW WORKLOAD TRACES. Workload traces from the PlanetLab project were added and used in the examples of the power package. The data have originally been provided as a part of the CoMon project, a monitoring infrastructure for PlanetLab (http://comon.cs.princeton.edu/). - SUPPORT FOR EXTERNAL WORKLOADS. External workloads written in the Standard Workload Format (SWF, from the Parallel Workload Archive) can be loaded and read by CloudSim. Relevant classes are WorkloadModel and WorkloadFileReader ('util' package). - SUPPORT FOR USER-DEFINED END OF SIMULATION. Users are now able to specify a given event that causes the simulation to finish. We thanks Gaston Keller for developing this new feature. REMOVED CLASSES --------------- - CloudCoordinator - Sensor - CloudCoordinator - PowerPe - Power.PeList API CHANGES ----------- - CloudSim.terminateSimulation(long time) was changed to CloudSim.terminateSimulation(double time), to comply with clock field of CloudSim class. - PowerModel was moved from PowerPe to PowerHost - VM allocation policies in the power package were replaced by a completely new implementation. BUGFIXES AND IMPROVEMENTS ------------------------- - Fixed issue 20: HostDynamicWorkload.updateVmsProcessing() throws NullPointerException. - Fixed issue 19: CloudSimTags class should be abstract, not final. - Fixed issue 17: "Something is wrong, the VM can's be restored" should be an Exception. - Fixed issue 16: cloudletsSubmitted in DatacenterBroker should be protected, not private. - Fixed issue 15: Simulation failed by the RAM where it should not fail. - Fixed issue 14: Rounding problem in VMSchedulerTimeShared. - Fixed issue 13: Output error when setDisableMigrations is set to true. - Fixed issue 12: Dynamically created space-shared VMs fail to process cloudlets. - Fixed issue 11: Wrong sharing of MIs among VMs by VmSchedulerTimeShared. - Fixed issue 10: Access modifier of DatacenterBroker::finishExecution(). - Fixed issue 9: Access modifier of DatacenterBroker::cloudletsSubmitted. - Fixed issue 7: Problem in manifests of Maven-generated jar files. - Fixed issue 5: Abrupt termination of the simulation caused by VmAllocationPolicySimple. - Fixed issue 4: Network examples do not load topology file. - Fixed issue 2: Turn the 'future' queue of CloudSim class protected. - Fixed issue 1: VM is created without check on host's storage capacity. - The power package and corresponding examples were heavily updated, as well as new PlanetLab workload data were added. - Fix in Datacenter: one initial update step was been skipped, what caused malfunctions in the schedulers. - Fixed issue affecting all CloudletSchedulers: if updated was less then 1, due to a small timespam, processing was never updated, because it was always rounded to 0. - Datacenter: Fixed problem with very short intervals between events. ----------------------------------------- Changes from CloudSim 2.0 to CloudSim 2.1 ----------------------------------------- - The project has been migrated to using Apache Maven (http://maven.apache.org/). Maven simplifies java project management by providing various tools and plugins for project building, testing, and packaging, dependency management, etc. - The directory structure has been changed to comply with the Maven specification - The VmSchedulerTimeSharedWithPriority has been removed as well as the priority field from the Vm class. Users can have the same functionality by using the VmSchedulerTimeShared class and setting the MIPS requirements for VMs. See examples 2 and 3. - Bug fixes, refactoring and removal of obsolete code. ---------------------------------------------- Changes from CloudSim 1.0 beta to CloudSim 2.0 ----------
