[GridSim-developers] Sample Code For Resource Discovery in GridSim

[Amir A. <man...@gm...>]

Hi dear.
I decide to implement a new resource discovery algorithm in GridSim.
Can you introduce me how can I write new resource discovery algorithm and
where I can inject (use) the code in GridSim architecture?
Please send me a sample code about writing and using resource discovery
algorithm.
Thanks for your attention.

[GridSim-developers] Questions about of GridSim

[Bernardo A. G. L. <bot...@gm...>]

Hello mailing list people of GridSim Toolkit

You receive a warm greeting from Colombia

My name is Bernardo Augusto, master student of Systems and Informatic
Departament of EAFIT University in the Medellin City.

I'm currently interested in surface the Toolkit of modelling and simulation
that you have developed called GridSim.

At this time i'm reading about of Grid Sim.
As a first impression (and what it says) GridSim is a framework for
modelling and simulation of Grid Computing but more oriented toward
the *management
and scheduling* of recource and applications?
This understanding a few at the level of execution of tasks or jobs across
the single and differents administrative domains (clusters o grids)  by
different users.

Grid Sim allow me make a work simulation about of performance evaluation in
an environment Grid Computing about of scheduling of jobs and process ? It
only, (without saying that it is somehow) or GridSim allowme more approach
in Grid Computing how emerging technology of Distributed Computing. This
last comment, from the perspective of applications on a grid
infraestructure,  or security about of environments federation and
applicatiosn developments (i review about of CloudSim, his other framework
of Cloud Computing, that says it)

CloudSim and GridSim have the API java-based for work in the frameworks.

Anyway my questions are also to support that i can get about of mailing
lists and the API in Grid Sim.
These is not discontinnued really ?
Also, i am the papers and related work make with GridSim in the differents
references to guide me.

 I appreciate the help, guidance and feedback you can give me

Hi Faisal
It is possible to change the characteristics of a Grid Resource, even
though it is little tricky. You have to extend the Grid Resource
class. And Generate an event (message) to Grid resource to update the
number of available machine.

Re: [GridSim-developers] Regarding GridSIM

[Saurabh G. <sau...@gm...>]

Hi Mohamed Mustafa
In v. 4.2 PEs are not connected to each other as such. thus, using
given code of gridsim 4.2 you can only simulate execution of bag of
task type applications. The higher version of GridSim support parallel
applications

To send gridlet  to GridResource, you have write the algorithm to
search grid resource with machines of best PEs, and then send gridlet
using Gridsim apis to that selected resource.

Hi Mayuri,

GridSim is of course good to start from scratch to implement your own ecosystem. Alea is based on GridSim and provides a lot of instant available features, such as a centralized meta-scheduler(high-level scheduler), processing capability of multi-CPU request jobs, etc. MaGate is also established on GridSim but work in a different direction. MaGate is using a self-structure P2P approach as its Information System and every node has its own high-level scheduler therefore no centralized point exist in the system. Meanwhile, MaGate integrates a simplified community aware scheduling protocol focus on reactive & dynamic scheduling (the protocol is accepted by IEEE AINA 2010 and IEEE ICDCS 2010, I hope an available version can be accessed soon). However, the MaGate is an ongoing work. The current available version from the website is a little old. If everything is fine, a new version is supposed to be published in May during a workshop in UK.

Cheers, 

Ye

Hi Mayuri,
Gridsim will allow you more better control over your simulation, Since
you can design your own simulator by using GridSim APIs and souce
code.  Magate and Alea are simulators build over GridSim to ease
simulation of particular scenario.

Re: [GridSim-developers] about the transfer time of gridlets

[Hamid M. F. <ha...@dp...>]

It's not possible. because when you measure the submission time of 
gridlet by getSubmissionTime() method, it return the time of task 
submission without considering the input transfer time. I mean if for 
example you spend 100s to transfer your input it return 101 as 
submission time and it is not clear when data begins to transfer and 
when it is finished.

Re: [GridSim-developers] about the transfer time of gridlets

[Agustín C. H. <ag...@ds...>]

Perhaps, u could store the time when a gridlet reaches a resource (class
GridResource, function processGridletSubmit), along with the time when
the gridlet is submitted (class GridSim, function gridletSubmit). This
way u can calculate the transfer time for input files.

Then, something similar can be done for the output files.

Agustin

Thanks for your guidance.
But I need to measure Input transfer time and Output transfer time 
separately. do you know any way for this?

Well, u can just keep the time when the gridlet is submitted and the
time when it is received (this is the total time of a gridlet), then get
the wallclocktime of the gridlet and substract it from the total time.

This way u get the transfer time, including both input and output files

[GridSim-developers] about the transfer time of gridlets

[Hamid M. F. <ha...@dp...>]

I need to measure the transfer time of gridlet's input and output, but I 
could not find anyway to measure it. I mean I wnt o know when the data 
(Input and Output) begins to transfer and when it finishes. Would you 
help me please.

[GridSim-developers] FW: need help in GridSim code

[SANA M. <dua...@ho...>]

Hi everyone,
i am doing a grid computing project, currently i am facing following problems, my code is attached here with the mail.

firstly, i want to pause gridlets to take a checkpoint of their executed portion but the state returned is the total length of the gridlets.
how and when should i pause these gridlets to take the checkpoint?
 
secondly, i want to replicate that executed portion on some nodes called checkpoint servers for storage, i studied data grid exemples but the replication done there is of file while i want to replicate data and if i replicate it as a gridlet then the receiving node will start processing on it, there is no built in method for checkpoint replication, can anyone suggest me the way to solve this problem?
 
thirdly, according to my system model grid is constructed of multiple clusters where each cluster (called resource in GridSim) have more than one checkpoint servers and i have to replicate the checkpoint on all of the checkpoint servers, now my question is that can we do such thing in simulation? i mean we define processing entities in resources that process the jobs, how can i just store the data on processing entities? or should i create just one linkedlist for a resource to
