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;

}

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. */

//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();

Appreciated , Thanx
