should i update the CloudletScheulerTimeShared or CloudletSchedulerSpaceShared?
No, you only call these functions from datacenterbroker in submitcloudlet() function to schedule the cloudlets instead of default algorithm FCFS
Dear Elhossiny thanks for your kind reply, it means that the scheduling algorithm what i have written and then called in the static main method is correct ???
and my one more relevant question is if i am concentrating on load balancing then should i only follow to use the CloudletSchedulerTimeShared?
all scheduling work is in datacenterbroker class where you call your scheduling method from it
Dear if you don't mind would you share a sample coded algorithm so i can follow the sequence or way to code (if i am wrong)....
i am forwarding you one of my code that i written for Shortest Job First, kindly check it out ... (i have done the min-min and max-min in the same way), kindly correct me in this regard
// this is the function that call you algorithm ( attached file )
public void psoScheduling(){
CloudLetPSOScheduling a = new CloudLetPSOScheduling();
//will retrieve the solution by PSO as an array of integers
//where every element in the array is the VM-ID
//and array index is the cloudlet number in the list
int[] newPostitionsOnVMs = a.getScheduledCloudLets(cloudletList, vmList);
for(int i = 0 ; i < cloudletList.size(); i++){
cloudletList.get(i).setVmId(newPostitionsOnVMs[i]);
}
}
---------------------------------------------------------
protected void submitCloudlets() {
//here call the function
psoScheduling();
int vmIndex = 0;
for (Cloudlet cloudlet : getCloudletList()) {
Vm vm;
// if user didn't bind this cloudlet and it has not been executed yet
if (cloudlet.getVmId() == -1) {
vm = getVmsCreatedList().get(vmIndex);
} else { // submit to the specific vm
vm = VmList.getById(getVmsCreatedList(), cloudlet.getVmId());
if (vm == null) { // vm was not created
Log.printLine(CloudSim.clock() + ": " + getName() + ": Postponing execution of cloudlet "
+ cloudlet.getCloudletId() + ": bount VM not available");
continue;
}
}
Log.printLine(CloudSim.clock() + ": " + getName() + ": Sending cloudlet "
+ cloudlet.getCloudletId() + " to VM #" + vm.getId());
cloudlet.setVmId(vm.getId());
sendNow(getVmsToDatacentersMap().get(vm.getId()), CloudSimTags.CLOUDLET_SUBMIT, cloudlet);
cloudletsSubmitted++;
vmIndex = (vmIndex + 1) % getVmsCreatedList().size();
getCloudletSubmittedList().add(cloudlet);
}
// remove submitted cloudlets from waiting list
for (Cloudlet cloudlet : getCloudletSubmittedList()) {
getCloudletList().remove(cloudlet);
}
}
Thanks for your assistance with attached files...
kindly do check my sent file in earlier text and guide me if any error in that mean the way i coded shortest job first please...

can you send your code for min-min and max-min scheduling of cloudlets to my gmail ([email protected])
Hello Altaf,
Can you send your code (Max-min & min-min algo) .I'm also working on the same.
Thanks
hello.
I want to change task scheduling algorithm and use Q-learning algorithm for allocate cloudlet to vm.What classes should be changed؟
another question : how to get the buffer for vm?
Anyone has min min and min max source code in cloudSim please share
or send to [email protected]
Dear Altaf Hussain i am working on min min and min max scheduling algorithm and i required the basic code of these 2 algorithm please send you code it will help a lot
I'm working on my bachelor project on Minimum Completion Time Min-Min load balanced algorith, It would be so much appreciated if any one send a work or a code or a research related to that, Thank you !
Hi Everyone , Anyone can send me Max-min & min-min task scheduling algorithm MatLab Code
Thanks.
Also every one can use
https://github.com/dapurv5/distributedscheduling
Min Task scheduler function in Java.
private void MinMin(Vector metaSet, int currentTime)
{
/*We do not actually delete the task from the meta-set rather mark it as removed*/
boolean[] isRemoved=new boolean[metaSet.size()];
/*Matrix to contain the completion time of each task in the meta-set on each machine.*/
int c[][]=schedule_MinMinHelper(metaSet);
int i=0; int tasksRemoved=0;
do{
int minTime=Integer.MAX_VALUE;
int machine=-1;
int taskNo=-1;
/*Find the task in the meta set with the earliest completion time and the machine that obtains it.*/
for(i=0;i
I am looking for Java code for Min-min and max-min Load balancing algorithms. Can anyone help me with that. Please send it to [email protected]
Pls I need the codes for Min-min and max-min Load balancing algorithms .Please send it to [email protected]
Good day all, I am working on my MSC thesis, I am improving max-min scheduling Algorithm with respect to makespan and resource utilization, please I need your assistance on how to calculate resource utilization.
Thanks
