Re: [GridSim-users] DataGridResource - processing DataGridlets

I've tried a dubious solution by changing the
DataGridResource.processOtherEvent(Sim_event ev) code.

Instead of passing the event to the localRC first and then to the Replica
Manager if it is not a RC event, I've changed the order so the event is
processed at Replica Manager firstly.

Now DataGridlets can be executed, but I still have no idea about the effects on
the rest of the cases or user operations with file replicas.

[GridSim-users] DataGridResource - processing DataGridlets

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

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

Hi everybody,

I'm using the gridsim.datagrid package and I'm trying to submit some
DataGridlets. These DataGridlets have some requirements regarding input files
which are not satisfied locally at the resources where they are submited.

In this case, SimpleReplicaManager asks for the location of the missing files by
sending CTLG_GET_REPLICA events to its DataGridResource. These events are
processed by the corresponding RC which eventually sends CTGL_REPLICA_DELIVERY.

The problem is that when DataGridResource receives this CTLG_REPICA_DELIVERY it
is processed by its localRC !!
Therefore, SimpleReplicaManager never gets the CTLG_REPLICA_DELIVERY, then it
never starts the following step (FILE_REQUEST),  so that DataGridlets with input
requirements that are not locally satisfied are never executed.

Do you have any idea/solution for this problem?

Re: [GridSim-users] parallel gridlet submission

[ye h. <hua...@gm...>]

Hi,
I'd like to recommend you to take a look at an AllocPolicy extended  
class named "AdvancedPolicy", which is developed by Dalibor Klusacek  
in his "Alea simulator". It allows the processing of a multi-PE  
gridlet. You need to ignore some logic because it's coupled with a  
centralized scheduler, however, I think the idea is valuable for you.

Re: [GridSim-users] question on demo of regional gis

[ye h. <hua...@gm...>]

Hi, Marcos:
I am working on GridSim4.1.

By the way, it also seems RegionalGIS has some special requirement on  
the policy used on GridResource, I am using a self-defined policy  
extended from AllocPolicy, but the resources could not be recognized  
by RegionalGIS. It seems I need to re-check my own policy class  
carefully :-p

Hi Ye,

What version of GridSim are you using?
I think I have come against this bug a while ago and I remember of  
fixing the GridSim version available at the trunk of the svn  
repository. I don't remember which version I fixed at that time.

Re: [GridSim-users] parallel gridlet submission

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

Dear Komagal,

The entities in GridSim are in fact Threads. I would recommend you to  
have a look at the SpaceShared policy, which schedules jobs in a  
cluster of machines. That might help you.

Also, if SpaceShared does not suit your requirements, you can create  
your own allocation policy for GridResource, which will behave like  
the master slave scenario you described. In this case, the policy you  
implement must extend the AllocPolicy class. The GridResource can  
have a list of machines (workers) and the allocation policy manages  
the allocation of these machines to the tasks received by the resource.

Regards,

Marcos

Re: [GridSim-users] many simulations with only a Java process

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

Hi,

technically speaking, it could be possible to run multiple simulation  
rounds in the same simulation process. SimJava's class Sim_system  
provides a feature that allows you to specify the termination  
condition, which I believe would allow you to specify the number of  
rounds:

/**
    * Specify a termination condition based on the confidence  
interval accuracy obtained for a default measure. This
    * condition is considered only once the transient period has  
elapsed. The accuracy is the ratio of the confidence
    * interval's halfwidth over the measure's total mean.
    * @param type                 The termination condition type.  
This must be set to <code>INTERVAL_ACCURACY</code>.
    * @param output_analysis_type The output analysis method to be  
used as a variance reduction technique
    * @param level                The confidence level for which the  
confidence interval will be calculated
    * @param accuracy             The accuracy that is required to  
satisfy the termination condition
    * @param entity               The name of the entity that  
contains the measure upon which the termination condition is based
    * @param measure              The <code>int</code> constant that  
represents the default measure upon which the termination
    *                             condition is based
    */
   public static void set_termination_condition(int type, int  
output_analysis_type, double level, double accuracy, String entity,  
int measure)

However, I have never tried this method before and I believe it will  
not work because for it to work, Sim_system makes a copy of the  
entities at the start of the simulation and puts them in a backup  
list. At each simulation round the entities are copied from the  
backup list back to the list of entities. The entities have to  
implement the Cloneable interface and I think that not all entities  
in GridSim implement Cloneable.

Alternatively, you can download the source code of SimJava2 and  
modify the Sim_system class to reset all static variables at the  
completion of the simulation. In this case, the code you have now  
would work. I believe that adding the following lines at the end of  
Sim_system.run() should suffice:

     incomplete = true;
     replications = null;
     total_time_elapsed = 0.0;
     total_transient_time = 0.0;
     min_batches = 10;
     max_batches = 20;
     run_data = null;
     trace_tags = null;
     default_trace = true;
     entity_trace = true;
     event_trace = true;

     entities = null;
     backup = null;
     future = null;
     deferred = null;
     clock = 0.0;
     running = false;
     onestopped = null;
     onecompleted = null;
     trcout = null;
     wait_predicates = null;

Regards,

Marcos

Hi, dear all:

I just encountered a problem while using RegionalGIS recently. Within

I was prompted the following error when I decreased its value to 1. It  
seems if I need to utilize RegtionalGIS, I should generate at least  
two regionalGIS, even one of it is empty, right?

Thanks!

[GridSim-users] Routing Problem

[Ashraf, J. <ja...@le...>]

Dear
To forward packets on a certain path I have to create a routing algorithm like RIP,
I am going to create OSPFRouter but I have few confusions
1: Which method of router class I am going to use for OSPF Algo.
2: I have to make decision at the first router to route through a mimimum delay path, how?
3: Another confusion is that how can I tell simulator that where to start the communication from? whether it depends on topology or can I set the starting point manually.

[GridSim-users] many simulations with only a Java process

[<coa...@ti...>]

Hello,
I am an Italian student of the Faculty of "Ingegneria 
Informatica" of University of Catane, using Gridsim for my thesis.
I'd 
like to know if there is a way to do many simulations with only one 
java process.

For example: I want to check how my scheduling algorithm 
reacts to jobs of different length:short jobs and long jobs.
To do this 
I want to make a simulation (SIMULATION_1) with a set of short gridlets 
and another simulation (SIMULATION_2) with a set of long gridlets.
I'd 
like to start these two simulations with only one Java process.

I've 
tried a possible solution: I've set up two thread one for simulation_1 
and one for simulation_2. I've put GridSim.init(...) and GridSim.
startGridSimulation() lines in the run() method of each of the two 
Threads.
Thread_1 works -> OK
Thread_2 doesn't work.
In fact, when 
Thread_2 runs, all the Grid_sim entities doesn't execute their body() 
method.

I am sure that Thread_2 starts only after that Thread_1 has 
Finished, because I've used the Thread.join() method and, in fact, on 
the screen appears:

"
...
Simulation completed.
Initializing GridSim 
package
...
"

where "Simulation completed" refers to the simulation_1 
and "Initializing GridSim package" refers to simulation_2.

What 
happens?

What else can I do?

Is there anybody who can help me, 
please?
Thanks.

[GridSim-users] EC-GIN partners would like to announce the release of grid application network simulators

[<m.m...@la...>]

Dear GridSim project members,

The EC-GIN project partners are pleased to announce the availability of
their grid application network traffic simulators for public release.
These simulators represent the conclusion of a work package aimed at
studying, modelling and replicating the network traffic generated from a
range of typical grid applications. This release currently includes four
separate ns2 simulators which model ATLAS, GridFTP, IPTV and PPLive (P2P
streaming) applications respectively, all of which can be tuned to
replicate a range of network conditions and streaming parameters.

The code is now available for download from the project website
(http://www.ec-gin.eu/corpsite/display/dsp_Entity.asp?en_id=696) and is
free to parties wishing to experiment with grid traffic. The simulators
are provided ‘as-is’ with the appropriate files, user guides and detailed
documentation describing their operation.

We believe that this work might be of interest to members of the GridSim
Project and we would greatly appreciate you taking to time to look at this
and circulating it to any other potentially interested parties. Please
feel free to contact us at: ns...@ec... if you require any further
information. Additionally, if you would like to learn more about EC-GIN or
be kept up to date with further developments, please see our main project
website at (http://www.ec-gin.eu/corpsite/display/main.asp)

Thank you for your attention, we apologise for this unsolicited announcement.

Yours sincerely,

Michael Mackay

Re: [GridSim-users] how to exchange CPU's MIPS into ClockSpeed(MHz)

[ye h. <hua...@gm...>]

Hi, Rajiv:
Thanks for your information.
Yeap, as you said, it seems to be pretty hard to achieve a directly  
map from MIPS to clockspeed. I am not intending to achieve an accurate  
exchange formulation(if exists), just trying to find/implement a  
simple (rough) exchange procedure.

Thanks again!
ye

The examples are the only training available for GridSim.

The packet routing and scheduling can be changed in order to simulate
different types of network links and for optimal path. There's nothing
"available off the shelf"

Not yet. But you can implement the functionality in the Network Router.

You are right. It denotes the size of the output produced by the
Gridlet once it is finished.

[GridSim-users] I want to simulate a workflow

[Ashraf, J. <ja...@le...>]

Dear members

I am about to start simulating a model on Gridsim, I dont have sufficient knowledge of gridsim. I have few questions regarding Gridsim

1:- Is there any training available for GridSim?
2:- I want to schedule a workflow of jobs/tasks on gridsim, so
    2(a) is it possible to implement Optical Burst Switching OBS Network
    2(b) What is the way to find the optimal path on the basis of multi cost parameters.
3:- Is it possible to do advance reservation for a "link"

It will be a great favor for me before I start simulating my model.
