Re: [GridSim-users] GridSim DiffServ JAVA source code availability

[Anthony S. <an...@cs...>]

Hi Zigmars,

The source code for network DiffServ QoS can be found on
the GridSim website. More specifically:
http://sourceforge.net/project/showfiles.php?group_id=94592

If you have problems with downloading it, then email me.
If you are welcome to contribute more functionalities into it.
I can create a new branch so you can use the SVN at SourceForge
for your development.

GridSim has two mailing lists:
gridsim-users (at) lists.sourceforge.net
- for any queries and feedbacks

gridsim-developers (at) lists.sourceforge.net
- for contributing to GridSim

Re: [GridSim-users] Help: how to simulate parallel file transfer.

[Anthony S. <an...@cs...>]

Hello,

Unfortunately, due to a design issue, an entity in GridSim can only
connect through one Input and Output port. This is also due to SimJava
definition of ports, i.e. they are unidirectional (1-way)
communication links.

To be able to send 3 files simultaneously, I may suggest that you use
the Rate-controlled scheduler, see the example on
http://www.gridbus.org/gridsim/example/net_index.html#gridsim_ex4

In the simulation setup, you partition the link bandwidth into 3 different
percentages, say 30%, 30% and 40%. Then file A, B and C have different
ToS. However, I am not completely sure whether all of them will be 
arriving at the same time (if they have the same size), since
packets are enqued and dequed at the I/O ports and routers.

Try this and tell us whether it works on not.

You can do this by means of events. This is, an entity extending 
GridUser can execute the following code:

super.send(destID,
GridSimTags.SCHEDULE_NOW + delay,
GridSimTags.EVENT_CODE,
data_object);

This code sends an "EVENT_CODE" event, from he current entity to the 
entity "destID". The event is delivered at the destination with a 
"delay", and the event carries the "data_object" data.

Then, in the destination entity, u must catch the event. For example, in 
the body method u can have something like this:

...
case GridSimTags.EVENT_CODE:
processEvent(ev);
break;
...

In the processEvent(ev); function u must get the data from the event and 
perform the processing u need.

There is no difference, because in the first one u provide the baud rate 
of a link that will be created in the method, and in the second u 
provide the link object already created.


Hope this helps. If u have any doubt, don't hesitate and ask us again.

All the best,

[GridSim-users] problem

[易侃 <yik...@si...>]

hello everyone:
I have build a topology of grid environment by gridsim toolkit, but I want Gridresources comunicating with a Scheduler without network. How can I do this?
In addition, is there any difference between the following  constructors:

Re: [GridSim-users] Could you help me to

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

Yonggang Liu,

You are right, the current space shared policy of GridSim converts the
parallel gridlets into sequential ones and executes them using one PE
only. You could implement your own allocation policy that allocates
multiple PEs to one gridlet. You can use the space shared policy as an
example.

Alternatively, you can use an extension of GridSim on which I have
been working. Please note that the extensions have not been
incorporated into GridSim. The source code is available as branch 3 of
the SVN repository at sourceforge.net. I have been working on it and
making a few changes, so the source code may occasionally change. The
policies implemented there include aggressive (EASY) backfilling with
configurable number of pivots (e.g. similar to the MAUI
implementation) and configurable job ordering heuristics, conservative
backfilling, among others.

Please note that this code is not part of the GridSim distribution. If
you do use it, please let me know whether you find any bugs on it or
not.

Regards,

Marcos

Re: [GridSim-users] How can i simulate file transmission

[Srikumar V. <sri...@gm...>]

Hi,
    First, set up the desired network topology. Using InfoPacket in
GridSim determine the bandwidth of the link you want to send the file
through. Compute the total time required for sending the file with
that bandwidth (total_time=size/bandwidth). Send the first packet of
the file and then send the last packet of the file after total_time.
You will have to write your own methods to do this though.

Cheers

Srikumar.

Re: [GridSim-users] Regarding information about Simjava

[Anthony S. <an...@cs...>]

See the readme file:
http://www.gridbus.org/gridsim/doc/README.txt


Installation and Running GridSim Toolkit
----------------------------------------
There is no special program to install GridSim. You just need to
unzip the GridSim file to install.
If you want to remove GridSim, then remove the whole $GRIDSIM directory.

NOTE: You do not need to compile GridSim source code. The JAR file is
       provided to compile and to run GridSim applications.

Description of the following jar files:
* gridsim.jar  -- contains both GridSim and SimJava v2.0 class files
* simjava2.jar -- contains SimJava v2.0 class files only

To compile and run GridSim applications, do the following step:
1) Go the directory where the GridSim's Example1 reside
    In Unix or Linux: cd $GRIDSIM/examples/Example01
    In Windows:       cd %GRIDSIM%\examples\Example01

2) Compile the Java source file
    In Unix or Linux: javac -classpath $GRIDSIM/jars/gridsim.jar:. Example1.java
    In Windows:       javac -classpath %GRIDSIM%\jars\gridsim.jar;. Example1.java

3) Running the Java class file
    In Unix or Linux: java -classpath $GRIDSIM/jars/gridsim.jar:. Example1
    In Windows:       java -classpath %GRIDSIM%\jars\gridsim.jar;. Example1

NOTE:
* $GRIDSIM or %GRIDSIM% is the location of the GridSim Toolkit package.
* If you are using Java IDEs, such as Eclipse, JBuilder and JCreator,
   their instructions (with screenshots) are found on the GridSim website.
* Running GridSim of this version requires a lot of memory since there are many
   objects to be created. Therefore, it is recommended to have at least 512MB RAM
   or increase JVM heap size when running Java for large simulation experiments.
   For example: java -Xmx300m -classpath $GRIDSIM/jars/gridsim.jar:. Example1
   (max. heap size is 300MB).

Re: [GridSim-users] Time Control in GridSim

[Agustín C. H. <ag...@ds...>]

Hi Jack,

The way u can do that is by means of events. Resources can send an event 
to themselves, and on the reception of the event, they can do the 
statistics u want.
The way to implement that is quite easy. In the body function of 
resources u have to add some piece of code like the following:

super.send(super.get_id(),
                       time_period,
                       YOUR_EVENT);

and, in the processEvent() function, u have to catch that event.

Hope this is useful,

Agustin

Re: [GridSim-users] reconfiguration dynamic

[Gilberto C. <gil...@gm...>]

Thanks, Vanderq

I'm sorry my poor english.

But i want switch the schedule algorithms *in run time during the simulation
*, agreed with different situations of the Grid.

For example:


   - If the number of arrival rate job is high, i would like use the
   algorithm 'X'.
   - But if number of arrival rate job is decreasing (until be low) , i
   would like my scheduler switch the algorithm 'X' for use algorithm 'Y',
   during the same simulation.

I would know how edit the parameters arrival rate jobs and how switch the
algorithms during the same simulation by dynamic reconfiguration. Because, i
would build a scheduler adaptive for different behaviours of the Grid.

Regards,

Gilberto Cunha Filho

[GridSim-users] reconfiguration dynamic

[Gilberto C. <gil...@gm...>]

Hi! Alexander,

Good talk you again.

I had another doubt. I would like in my experiments to switch scheduling
algorithms during the simulation (run time),
for  differents situations of the Grid. For example, any algorithm batch for
high rate arrive jobs and any algorithm
on-line for low rate arrive jobs.

But i don't know, if GridSim provide support for switch algorithm. If not
offer support, i would like
implements this switch by reconfiguration dynamic with adaptive framework
(Adapta, used in my university).
Because in master thesis i will analyse the switch the algorithms
for use in Grid when happen differents situations and i would like simulate
and analyse
its.

Tanks, for your atention

[]'s,

[GridSim-users] How to leave information in visited nodes ?

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

I want to move a *Gridlet* from one Machine to another and I want to 

leave some information in the nodes which the *Gridlet* is visiting as 

it moves towards its destination.

 

I couldn't find this capability in *GridSim*. Could you please help me 

if there is a way.

  

 

Thank you very much in advance,

Re: [GridSim-users] dynamic job arrivals ...

[ALexander v. d. K. <va...@ho...>]

Hi Gilberto,
=20
No problem, glad to help.
=20
The execution time of a job depends on the size of the job (Gridlet length)=
, and the characteristics of the resource executing the job.
The faster the resource, the smaller the execution time. And the smaller th=
e job, the smaller the execution time.
=20
Basically, in a space shared resource, you can calculate the execution time=
, just by dividing the length of the Gridlet/job by the speed of the Proces=
sing Element (PE) of the resource.
However, you might not now the waiting time at the resource. If a job arriv=
es at a resource, and no free PE is avaiable (all are busy), it is placed o=
n a waiting queue. With no other information available, you can't calculate=
 the waiting time. This is possible if you exactly know all the job lengths=
 and submission times, and there is no (random) background noise at the res=
ource.
=20
You can configure the resource to behave exactly as you want by modifying t=
he GridResource.java source file, and using the modified and compiled versi=
on to create the resources.
=20
Kind regards,
Alexander

It depends on how you design/program GridSim.If you know which jobs have be=

Re: [GridSim-users] dynamic job arrivals ...

[ALexander v. d. K. <va...@ho...>]

Hi Gilberto,
=20
I'm not sure if I understand your question. With conclusion time, do you me=
an the response time (time between submitting and receiving the job)?
It depends on how you design/program GridSim.
If you know which jobs have been sent to which resource, you should be able=
 to calculate the various properties of the job execution (queue time, exec=
ution time, cost, response time, etc.).
For space shared resources, this is of course easier than for time shared r=
esources.
For 1 user you can do this within the NetUser class. Else, a central entity=
 which controls the submitting of jobs to the various resources might be a =
suitable approach.
=20
Does this answer (part) of your question?
=20
Kind regards,
Alexander
