[GridSim-users] how to manage time in GridSim?

[SARDOR H. <rod...@ma...>]

Hello everybody. I'm implementing my new load balancing algorithm in GridSim.
 I stuck at one problem. Actually I wanted to send load state information from Resources to Cluster Managers every fixed period time.
 But I couldn't do it. I'm doing like that:

start_time=GridSim.clock();
border_time=start_time+T; // every T resource sends its load state information to Cluster Manager
Sim_event ev = new Sim_event();
        while(Sim_system.running()){
            current_time= GridSim.clock(); // System's current time
            if(current_time>=border_time){
                super.send(cluster, GridSimTags.SCHEDULE_NOW,File.TYPE_TAG_DATA, data);  // data is load state information
                System.out.println(name_+"is sending its EET "+t[myQ.size()] +"to "+cluster+" at time "+GridSim.clock());
                border_time=border_time+10;
            } 
           super.sim_get_next(ev);
..... 
   
Can Somebody help me to solve this problem, please.
Thank you in advance!

[GridSim-users] question

[malihe s. <mal...@ya...>]

merci.

but I execute gridsim.jar for compile in dos.
I for execute examples of gridsim should they open in the netbeans?
you can tell me how is output?is text?
 
I intend write a scheduling algorithm, but I do not know in which part should be written?
 
For creating user in gridsim i can use from visual modeler?Can be linked?

[sara s. <sar...@gm...>]

Hi,

I have GridSim5-2, Java 1.6 and MyEclipse 10 on my system. When I run
an example(example 4) of DataGrid in MyEclipse, it gives me this
error:

Could not find the main class: path\to\example\MainClass.java.
Program will exit.

Please give me some points ...

 Hi,
I'm working on a paper and need to do simulations in Gridsim. But when my nodes are more than about 800, I received this error:

    Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: unable to create new native thread

Would you pleases
 tell me how to overcame to this error.

[Amani G. <ama...@ba...>]

hello

regards example 6 i want to make sure of some details:

1- it has 3 users apply their workload Gridlet into 3 different machines  Resources and we compute the time cost of getting the answer?

2- in my simulation i can change the file input size or the speed of machine or MI ?  to get various results and study the effects ?

3- if the above is right what else do you think i can change to draw in my excel graph?

please i am new to Grid sim i know i must spent more time in it but really i have just week to finish this so any help or advice is highly appreciated

thanks

[GridSim-users] example 6

[amani <ros...@ya...>]

hi 


i am working on example 6 of gridsim i was able to compile and run it but i don't understand it !!!
what parameter i can change is it just 3 users want to access 3 resources and we want to compute the access time??
the parameters that i can change in my simulation?
any ideas or useful resource help plz

[GridSim-users] Question for a network with multiple links

[Nirali N. <nir...@gm...>]

Hello All,

I am quite new to Gridsim and i am trying to set up a fully connected
network where each node is linked to each other node.
Each node has computations to do and parameters to pass to other nodes.
I tried the first example in "network" folder for 2 users. However that
does not accept multiple links for multiple users.
Can someone please help with guidance regarding which example would be apt
for my situation.

[GridSim-users] Want to develop new Back Filling Algorithm

[farah i. <far...@gm...>]

hi,i am doing my mtech project in grid computing in Advance Resource
Reservation and with that i want to combine the new back filling algorithm.
i am done with user,resources and scheduler for communication, and advance
reservation also working too good,but for back filling i want free PE and
time slots from resources. but ARResources should use ARSimpleSpaceShared
policy and this policy not allowed queryFreePE and queryFreeTime,and also
not allowing to process 1 gridlet on more than 1 PE. so please anybody help
me out and tell me what to do? what policy should i use. if i go for
parallelResource so which AllocPolicy allow more than 1 PE for 1 gridlet.
OR
should i need to write down new policy for this?
actually i am working on it but suppose any body have better solution than
this,so please share that with me.

thank you so much in advance.

Have Happy Grid!!!! :-)

[GridSim-users] Flow network model accuracy issue

[Martin Q. <mar...@lo...>]

Hello,

I was curious about the kind of accuracy that could be expected from
the flow based model, so I decided to run an example that would be
simple enough to be computed by hand, just to see.

I simplified one of the provided examples to get a fully symmetric
backbone, with 2 flows of the same size starting at the same time. 

The expected outcome is that the flows terminate at the same time,
about twice the time to send a single message without contention on
the backbone link.  But instead, only one of the flows seem to share
the bandwidth on the bottleneck link while the other doesn't.

That is to say that sending a single flow takes 83.2 seconds while
when sending 2 flows, one of them takes 83.2 seconds while the other
takes 163.8. 

My question here is to know whether I did something wrong in my test
case (attached to this mail), or whether this, as it seems, a bug in
GridSim. I'm using GridSim v5.2.

If someone has a fix or a workaround to solve my problem, please help. 


Thanks in advance,
Mt.
