[Announcement] CloudSim 3.0.3

[Nikolay]

Hi All,

We have just released a new version of CloudSim: 3.0.3. It is mostly a bug fix and refactoring release. The following updates have been made:
- Removed the dependency on the flanagan library. It is now replaced with Apache Math. The implementation and interface of the MathUtil has been changed accordingly.
- The minimal time between events is now configurable.
- Fixed Issue 44 : UtilizationModelPlanetLabInMemory: use a global constant to define the size of the data field: a new constructor for the classes, allowing definition of data size, was added.
- Fixed Issue 49 : Wrong calculation of debt during migration: all references to debt from Datacenter and its subclasses were removed.

It is important to note that the flanagan library is no longer needed, and Apache Math is used instead. This may cause minor numerical differences in the results from the power package obtained with previous CloudSim versions and this one.

The new version can be downloaded from the usual place: http://code.google.com/p/cloudsim/downloads/list

If you find any new issues, please submit bug reports: http://code.google.com/p/cloudsim/issues/list

Best Regards,
The CloudSim Team

Hello Nikolay

I am currently working on cloudsim 3.0.1 and trying to bind particular broker to particular datacenter, is there any inbuilt function for this in version 3.0.3, if no can you plz guide me where exactly i should make this function, currently i have made this in datacenter class but there is some logical error.

Thanks in advance.

Hi Nicolay

im new with cloud sim & i'm using it to simulate an optimisation in resources allocation to minimize SLA violation under heavy load

so to start i'v created a data center with one host 1 cpu, 1000mips, 1024 ram, 10000 bw ....etc

& i'v allocated 1 vm with 1cpu 500mips,512ram.1000bw, imagesize 10000 ...etc

& i executed cloudlet withe diffrent size => different execution time and the coste stille the same
the DatacenterCharacteristics is like this

double cost = 3.0; // the cost of using processing in this resource

double costPerMem = 0.05; // the cost of using memory in this resource

double costPerStorage = 0.001; // the cost of using storage in this resource

double costPerBw = 0.0; // the cost of using bw in this resource

the cost is 35.6 no matter haw long the execution was

the cost is calculated by ( amount of ram * costPerRam ) + ( imagesize * costPerStorage ) 

i'v tried to change the variable cost = 0.3 & nothing happen 

in my work i'm trying to simulate pricing by used time of both ram & cpu if any one have some info about the cost and why it doesn't affect any thing  and how to calculate cost by used time ,

please give me some answers about cost or if the cloudsim can simulat SLA pricing

thanks in advance
