Output error when setDisableMigrations is set to true #13

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

To run fine:
1. Open SingleThreshold.java example.
2. Run.
3. Check the output for each cloudlet.

To run with errors:
1. Open SingleThreshold.java example.
2. Set datacenter.setDisableMigrations() to true 
[datacenter.setDisableMigrations(true)].
3. Run.
4. Check the output for each cloudlet.

In the second case there is no output for cloudlets.

What is the expected output? What do you see instead?

Expected:

Something like:
"

What version of the product are you using? On what operating system?
CloudSim 2.1.1.

Please provide any additional information below.
Something bad happens when the migrations are disabled (ie: this also occurs at 
DVFS.java example).

There is an obvious workaround to get the cloudlets list:

Instead using SimFunctions.printCloudletList(cloudletReturnList) if you use 
SimFunctions.printCloudletList(cloudletsList) you will print all cloudlets, 
including their correct start and finish time, and "SUCCESS" as status, so the 
problem is with the disabled migrations only.

All the power examples have been updated, including the output. Please try the 
new code from the repository.
