I am working on VM live migration strategy. In order to have live migration, I have to give workload to the environment. Currently I am using cloudsim, Can any one suggest the way to add external workload in cloud sim?
Hello Mr. Muhammad Zakarya,
I have learn those examples. I want to use external workload. I don't know how to that?
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).
firstly download a workload from this site for example :
http://www.cs.huji.ac.il/labs/parallel/workload/logs.html
secondly add it in your example like this:
private static List createCloudLets() throws FileNotFoundException{
/** The cloudlet list. */
List cloudletList;
//Read Cloudlets from workload file in the swf format
WorkloadFileReader workloadFileReader = new WorkloadFileReader("E:\\research\\olimatco-ut_cloudsim-01a738e02d92\\olimatco-ut_cloudsim-01a738e02d92\\Simulation Files\\HPC2N-2002-2.1-cln2.swf", 1);
//generate cloudlets from workload file
cloudletList = workloadFileReader.generateWorkload();
return cloudletList;
}
Thanks a lot Mr.Shafi’i M Abdulhamid and Mr. Elhossiny Ibrahim .. It's really a great help.
You can also use CloudAnalyst where you can add your workload in GUI. CloudAnalyst is an extension of Clousim.
Tarannum Bloch , possibly tell me please how to create cloudlets with workloadtraces in cloudsim, I used the above answers but my code has problem.
CloudSim Plus has an example of how to use workload traces in SWF format at https://github.com/manoelcampos/cloudsim-plus/blob/master/cloudsim-plus-examples/src/main/java/org/cloudsimplus/examples/traces/SwfWorkloadFormatExample1.java
An SWF workload can be loaded by calling reader = SwfWorkloadFileReader.getInstance(filePath, VM_MIPS)
where:
- filePath is the relative of an SWF workload file inside the resources directory or its full path;
- VM_MIPS is the MIPS capacity of the VM where the Cloudlet is supposed to run. Check the class documentation for more details.
It also fixes some issues and includes some features, such as:
- https://github.com/manoelcampos/cloudsim-plus/issues/154
- https://github.com/manoelcampos/cloudsim-plus/issues/115
- https://github.com/manoelcampos/cloudsim-plus/issues/119
Additionally, it supports creating simulations based on Google Cluster Data traces: https://github.com/manoelcampos/cloudsim-plus/releases/tag/v4.0.0
The official website is http://cloudsimplus.org
WorkloadModel r = new WorkloadFileReader("src" + java.io.File.separator + "workload" + java.io.File.separator + "dataset.gz", 1);
list=r.generateWorkload();
how can i download actual dataset for scheduling algorithm and also add that dataset in cloudsim...?
public class Test
{
private static List cloudletList;
public static void main(String args[]) throws FileNotFoundException
{
WorkloadFileReader wfr=new WorkloadFileReader("E:\\workload\\NASA-iPSC-1993-2.1-cln.swf", 1);
cloudletList=wfr.generateWorkload();
System.out.println(cloudletList.size());
}
}
It gives output=0
Hi,
Can Anyone suggest me how to use generated cloudlets from this link https://www.researchgate.net/deref/http%3A%2F%2Fwww.cs.huji.ac.il%2Flabs%2Fparallel%2Fworkload%2Flogs.html? I have got the following results
# Created 51987 Cloudlets for DatacenterBrokerSimple1
# Created 21602 VMs for the DatacenterBrokerSimple1
# Added 10801 Hosts to Datacenter 2
21602 VMs from Broker 1 placed into some Host.
How to test this for resource utilization by applying VMAllocation policy?
Please suggest me step by step procedure to carry out the experiment.
I am working on VM live migration strategy. I wrote one simple client-server program using java. The client requests a value from the server and the server will return the value as per the client's request. The value is updating and in each call, the client will get new. This client activity is going and in between VM migration will be called.
Can we simulate this scenario using Cloudsim? I need to put the workload as this client activity.
If anyone know, please help
I have a query:
Are workload traces from "http://www.cs.huji.ac.il/labs/parallel/workload/logs.html " can be considered as real workload?
Yes this workload can be considered as real workload as recognized by CloudSim
