[GridSim-users] Handling Interrupts

[Ronnie F. <ron...@gm...>]

Hi,

I am interested in designing a pre-emptive scheduler, or some way to handle
interrupts. What is the best way to accomplish this using GridSim?

Are there any tutorials / examples, or any other sources I could use as a
reference to handling this problem?

Thanks,
Ronnie

[GridSim-users] GridSim Examples

[Ronnie F. <ron...@gm...>]

Hi,

I am new to GridSim, and trying to run through the examples. I am able to
compile the Example01.java, and I see a file Example01.class appear in the
directory. However when I try to run Example01 I get en error message. I
read the FAQ page that talks about my error, but I am still not able to run.
I have tried multiple things, but still no luck. Please help.

There is some ambiguity on the site about how to run the file:

On the FAQ page it says:

* to run type: java -cp %GRIDSIM%\jars\gridsim.jar;. gridsim.example01.Example1

 On the Readme file it says:

In Windows:       java -cp %GRIDSIM%\jars\gridsim.jar;.
gridsim\example01\Example1

I have tried both versions but I am still getting the error.

%GRIDSIM% for me = C:\eclipse\GridSim

What I have tried is:

C:\Program Files\Java\jdk1.6.0_21\bin>javac -cp
C:\eclipse\GridSim\jars\gridsim.
jar;. C:\eclipse\GridSim\examples\gridsim\example01\Example1.java

C:\Program Files\Java\jdk1.6.0_21\bin>java -cp
C:\eclipse\GridSim\jars\gridsim.j
ar;. C:\eclipse\GridSim\examples\gridsim\example01\Example1

I have also tried:

C:\Program Files\Java\jdk1.6.0_21\bin>java -cp
C:\eclipse\GridSim\jars\gridsim.j
ar;.
C:\eclipse\GridSim\examples\gridsim\example01\gridsim.example01.Example1

This is the directory that Example01.class is stored:
C:\eclipse\GridSim\examples\gridsim\example01

And the following is the error message I receive:

Exception in thread "main" java.lang.NoClassDefFoundError:
C:\eclipse\GridSim\ex
amples\gridsim\example01\Example1
Caused by: java.lang.ClassNotFoundException:

Could not find the main class:

I have tried many things, but am unsure why it is not running. If you could
walk me through where I am going wrong it would be greatly appreciated.

Thanks,

[GridSim-users] creating grid users and resources in the middle of simulation

[Aminul H. <ami...@mo...>]

Dear users,

Would you mind please let me know that is it possible to create some
additional resources/users after some period a simulation has been started
in GridSim. It has to be during a single simulation, so GridSim will
initialise (GridSim.init()) only once and also simulation will be initiated
(StartGridSimulation()) only once. The additional resources will then be
added with the existing resources.

Waiting to hearing from you..?

[GridSim-users] GridSim Simulation of Load Balancing Algorithm

[Jyoti P. <jyo...@gm...>]

What is the way to simulate Value Function Algorithm in Gird Sim ?

The algorithm is as follows

1. for all nodes calculate value function given by V = W1*CPU-usage +
w2*memory-usage + w3*network-usage
2. sort the value function and allocate the tasks to the corresponding nodes

Dear all

 I have a problem in running my program with gridsim.

I try to run one of Gridsim parallel example that schedule with conservative
back fill algorithm. in the ConservativeBackfill class there is a function
that name is compressSchedule. but it does not use  in real program of
ConservativeBackfill, then I want to use it. I use actual finish time and
expected finish time, then when the job finish I call compressSchedule
function to compress jobs in queue but in run time, program has an error
that is :

Re: [GridSim-users] Kindly reply for Query regarding load balancing in GridSim

[Abdul <abd...@ya...>]

You can try this for getting a free PE "getNumFreePE" for all the Machines


Also for IO, you can use "getBaudRate" from "Interface NetIO" and
"setPacketSize" from "TrafficGenerator"


You might be able to use "getAvailableSpace" from Class HarddriveStorage


Someone should comment regarding CPU utilization rather than getting a free
PE and Memory belonging to a PE/Machine/Resource, if any

Dear all,

We are simulating Dynamic load balancing algoirthm using GridSim. As per our
algorithm, we want to collect CPU utilization, Memory utilization and I/O
utilization of different resources to calculate load of the resource. We are
using network examples of GridSim for the same. However, we donot know that
from where to collect memory and I/O utilization of resources?

 

Can you please guide us for the same?? Even we donot know that whether it is
possible or not in Gridsim to collect memroy and I/O utilization. 

Can we add our own module for the same? if So, how?? Please give your expert
comments on the same.


 

(2) we also want to divide nodes into different groups. please guide us that
how is it possible with gridsim as it is the primary requirement of our
proposed load balancing algorithm.

Re: [GridSim-users] PSO algorithm in grid computing

[Pablo C. <pc...@ac...>]

That's a pretty much generic question. Maybe you could elaborate on what 
part of the implementation
you are finding difficult to map to gridsim. Maybe the mapping from PSO 
to gridsim's architecture?
maybe the need for some particular functionality? Also, giving some 
explanation on how do you
plan to use PSO to grid schedulling would be very beneficial.

[GridSim-users] globus

[Mahdi M. <mot...@gm...>]

Tnx Alex. but what about Globus toolkit? can I use it for my resource
discovery model?
or any other tools?
what is my solution to test a new resource discovery model for grid
networks?

Re: [GridSim-users] gridsim use

[Alex G. <fro...@ya...>]

You just need to download the jar file from the GridSim official site and then 
you should go through the first 10 basic examples.
Mind you that GridSim is not intended for resource discovery testing and it 
provides it's own Grid Information Service/s.
In order for you to test something other than resource allocation and task 
submission policies you'll have to implement and modify some of the native 
GridSim mechanisms.

Cheers,
alex
