Execution of examples in cloudsim

[rashmi k.s]

Hello

I have created my own classes namely PowerDatacenter, PowerDatacenterBroker, PowerVmAllocationPolicy etc and implemented them in the DVFS example given in the cloudsim package. But on execution I am getting following errors. Please can anybody tell me how to get arround them.

Hi Fahimeh

I am so sorry for not replying ur previous email. i am so busy.by the way, it is so easy. u should change the input of CreateVMs() method. i mean u should change input of method from 50 to 20. so go to Random Constant.java class and change it. chunk of code is below:

public class RandomConstants {

public final static int NUMBER_OF_VMS = 20;

public final static int NUMBER_OF_HOSTS = 10;

public final static long CLOUDLET_UTILIZATION_SEED = 1;

}

also ur class name is ThrMU= threshold,Minimum Utilization  dont make mistake.

So Simple!

Cheers

Neda

Hello Neda

I'm working on the same thing,

I tried to follow your instructions, i changed no. of hosts and vms but still in the result shows 50 vms and 50 hosts.

In the same manner, i want to change no of cloudlets or generate them dynamically, where should i change?

Please help, its urgent.

Any one know can help.

Thank you

I think you have not saved before running that is why. 

I did the same and I got 20 VMs and 1 Hosts.

hi,
please send me all codes related to power(Number of SLA violations,Total simulation time,Number of VM migrations,Average SLA violation). and how to calculate vm performance degradation on host.
thanks
