[GridSim-users] Gridsim busy waiting

[Vaibhav A. <vai...@gm...>]

I am Vaibhav Arora, an undergraduate student of Computer Science in National
institute of
Technology, Trichy, India and am working upon an extension to a existing
scheduling algorithm in Grid environment.

I am working with grid sim.I have a arcitecture in which I have sites and
each sites are machines ,both are grid sim entites.

I have a probelm as in I have a entity which doing some work in a loop but
there may be some request coming from some other entity while it executin
the loop.Then I want the task to care of event.How can we take care of this
in grid sim.
Analogical condition is that a person is doing some work and there is knock
on the door and he then services this event.
I cant wait for the event in a loop as it may or may not happen.

How to do this in gridsim??
I will be thankful for any replies.

Re: [GridSim-users] Creating a gridlet

[Marcos D. de A. <ma...@cs...>]

Hi Komagal,

GridSim is a discrete-event simulator in which the capacity of CPUs  
are expressed in Millions of Instructions per Second (MIPS); the  
length of a gridlet (i.e. job) is defined in Millions of Instructions  
(MIs). Therefore, you should model your job as a gridlet with a given  
number of MIs that reflect the executed operations. Please check the  
examples included with GridSim for more details.

Regards,

Marcos

Hi Sarah,

I think that java 1.4.2 doesn't provide the tools package. You should upgrade
the java sdk to 1.5.0 or 6.

Try this (as root):

apt-get install sun-java6-jdk
update-java-alternatives -s java-6-sun

Then try to compile it again with ANT.

I hope this helps

[GridSim-users] Parallel schedulers in GridSim

[Abhinav M K. <abh...@gm...>]

I am an undergraduate student of Computer Science in National institute of
Technology, Trichy, India and am working upon an extension to a existing
scheduling algorithm in Grid environment.

Description of the grid is as follows:

Grid consists of number of sites and site consists of machines.
Every site has a centralized scheduler which takes care of scheduling jobs
on the machines in that site.
If a job cannot be scheduled on any machine in a particular site then it is
migrated to some other site.

My requirement is all the centralized schedulers in the sites should be
working in parallel.
I do not know how to go about that. I'm expecting help in this direction.

Thanking You

[GridSim-users] about the cloud simulation

Hi,If I want to do some cloud computing simulation which in fact is related

Re: [GridSim-users] Background Traffic

[Leonardo F. <sa...@li...>]

Hi all,
I was trying to solve the problem I posted about the Background traffic and I found something wrong in FlowNetEx02:if traffic increases the execution time of the gridlet remains unchanged.
Instead without using flow-links(as in NetExample03), both the execution time and the RTT increases.
Someone has noticed the same thing or know if I am wrong?

Leonardo Fortuna

[GridSim-users] Background traffic

[Leonardo F. <sa...@li...>]

Hi,
thank you for your very useful answer to "Router Problem".
Now I have a question about using background traffic functionality.
To implement my algorithm I calculate the Round Trip Time to each GridResource.When I use background functionality I expect that RTT grows,while this does not happen. 
Any idea why or where I am wrong?
Best regards,
Leonardo Fortuna

Re: [GridSim-users] how to create a peer to peer network in gridsim

[Jonathan M. <jon...@bs...>]

Hi Geetha,

For instance, a topology with 3 routers router[A, B, C], with A connected with B
and C, and B, C connected as well:

3
routerA
routerB
routerC
routerA routerB 0.1 10 1500
routerA routerC 0.1 10 1500
routerB routerC 0.1 10 1500


If you write this on a file, for instance let's say
"/home/geetha/mynetwork.conf" you can use the following
java code example:


String path = "/home/geetha/mynetwork.conf";
LinkedList<Router> l = gridsim.util.NetworkReader.createFlow(path);


If you are not using the new version of GridSim, you can use
NetworkReader.createFIFO(path), but the simulation time increases exponentially
since this second function uses SimpleLink links which implies the creation of a
new entity object per network packet (in our example with MTUs = 1500, implies a
new object for every 1500 bytes transferred).


Regards,

	Jonathan

Re: [GridSim-users] how to create a peer to peer network in gridsim

[Jonathan M. <jon...@bs...>]

You cand define your own network topology in a simple plain text file such as:

#num of routers
5
#router ids
router1
router2
router3
router4
router5
#router links defined between two of them
#               bw(Gbps) delay(ms) (MTU)
router1 router2 0.1 10.0 1500
router1 router5 0.1 10.0 1500
router2 router5 0.1 10.0 1500
router2 router3 0.1 10.0 1500
router4 router5 0.1 10.0 1500

Then, you can use the gridsim.util.NetworkReader class to initialize the
topology (this class parses the file and creates the routers).

Finally you can attach resources and users to any of these routers.

Regards,

	Jonathan

PS: Use GridSim 4.2 with Flow links if you want to simulate data-intensive
gridlets. Otherwise, the time to execute simulation of data transfers among
resources, grows exponentially.

Re: [GridSim-users] gridsim

It fails because some singletons are used and AFAIK there is no clean way to
reset the variables. I also use an external script to execute the whole thing
several times (as some people has advised you).

But for instance Alea (a package based on GridSim for testing scheduling
algorithms) uses a modified simjava package that implements a method that resets
these inner variables.

Furthermore, if you are using another GIS (such as DataGIS), you will also need
to reset it, and the method setGIS is not enough, you need to "unsetGIS" first.
But this method is not implemented, so I coded it in GridSim class:

public static boolean unsetGIS()
{
    gis_ = null;
    return true;
}

That's all

super.send(resourceID, 0, DataGridTags.DATAGRIDLET_SUBMIT, g);


(Note that this is for DataGridlets, but basic GridSim package also has a
definition for GRIDLET_SUBMIT)


And afterwards I get the returning code:

Sim_type_p tag = new Sim_type_p(GridSimTags.GRIDLET_RETURN);
Sim_event ev = new Sim_event();
super.sim_get_next(tag, ev);


That's all

That functionality should work properly, since it is basic...

What errors u get?

Re: [GridSim-users] gridsim

[Agustín C. H. <ag...@ds...>]

Hi,

What I do is the following:

1- Once I've implemented my stuff, I create a .jar file. The tool u use 
to program (e.g. eclipse, jbuilder,...) will have details on this point. 
The .jar file can be executed by java -jar file.jar [parameters]

2- Then, create a linux script or a windows batch file containing your 
experiments. For instance, it could look like this:

    java -jar mycode.jar para1 para2 para3
    java -jar mycode.jar para1 para2 para3
    java -jar mycode.jar para1 para2 para3
    java -jar mycode.jar para1 para2 para3

    Pay attention that each experiment should write results in files 
with different names, otherwise u would overwrite the results of the 
previous experiments.

3- Once ur experiments are over, just implement a program that 
calculates averages, ... whatever statistical measures u need. Then, u 
can plot them using gnuplot.


HTH

Cheers,

Agustin

Subject: help
To: gridsim-users <gri...@li...>


I'm using gridsim 4.0 toolkit for my project.
i hav just now created the resources,users and gridlets in the grid
environment.
my next step would be to schedule the gridlets and allocate to resources.


my question is HOW TO SUBMIT A GRIDLET TO A RESOURCE? IS THERE ANY
FUNCTION IN THE TOOLKIT?

i hav already tried  gridletSubmit(Gridlet gl,int resourceID)
function..but i get errors..pl say how to give the gridlet to a
resource..pl...

[GridSim-users] gridsim

[guanzhou lu <ug...@cs...>]

Dear All:

I am currently using GridSim for a project, but I have encountered a
problem:
could GridSim simulation run several times in a single class or
function, because I want to take the average performance of the simulation?

As I wanna my program be like:
class gridsim(){
	main(){
		1st Simulation
		2nd Simulation
		...
	      }		

Is there any thread or something that I will need to destroy after 
calling the simulation? As the 2nd simulation does not work.

Does anyone has met the same problem or knows how to do? I would be
appreciate if you could help me on this.

Best,
Guanzhou

Re: [GridSim-users] GridSim simulation

[Azin M. <az...@ma...>]

Hi,

You can write an script to run the simulation several times, echo the 
results in a text file and load it in another program (like excel) and 
do any statistical operations you need.

I hope this helps,
Azin

[GridSim-users] Flow Links - GridSimCore

[Jonathan M. <jon...@bs...>]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi all,

Analyzing the code, I've found that my problem with new flow level network is
that there is a "pretty" static attribute in GridSimCore, which is initialized
to NET_PACKET_LEVEL by default...

[...]

/** Specifies which type of network to be used.
     * By default, the simulation uses the gridsim.net package or differentiated
     * network service. To change this default property, please use the
     * {@link gridsim.GridSim#initNetworkType(int)} method <b>before</b> the
     * simulation starts.
     * @see gridsim.GridSim#initNetworkType(int)
     * @see gridsim.GridSimTags#NET_PACKET_LEVEL
     * @see gridsim.GridSimTags#NET_FLOW_LEVEL
     * @see gridsim.GridSimTags#NET_BUFFER_PACKET_LEVEL
*/
protected static int NETWORK_TYPE = GridSimTags.NET_PACKET_LEVEL;

[...]


This implies that every creation of an entity based on GridSimCore (such as
users) initializes its Sim_ports in/out with Input/Output types... which are
incompatible with flow networking (that use FlowInput/FlowOutput).

To solve this...you can see the "note" in the javadoc of GridSimCore that tells
us how to change this attribute:

[...] use the gridsim.GridSim.initNetworkType(int) method before the
      simulation starts. [...]

But that is not completely true, because calling the method immediately before
GridSim.startGridSimulation is useless, since all the entities that are created
before starting the simulation would use the default NET_PACKET_LEVEL.

So eventually, the solution is using the method immediately after GridSim is
initialized (GridSim.init), instead of before starting the simulation.


Finally, my question to developers is, why do you use this static attribute
instead of taking the type of Link into account to know whether we want old
input/output or new flowinput/flowoutput?

Moreover, I think that you shouldn't expect that users find this note in
GridSimCore class documentation.


Thanks,
