[GridSim-users] Dearest One Please Be Honest

[Leona D. <mma...@gm...>]

Good day

I am 75 years old and was diagnosed with cancer approximately 
four years ago, immediately after the death of my husband.

I have been touched to donate from what I have inherited from my 
late husband for the good work rather than allowing his relatives 
to lavish it.

As I lay on my sick bed, I want you to help me in carrying out my 
last wishes on earth which will also be very profitable to you. I 
want to WILL a total of 5.5 M US to you which I want you to use 
part to help innocent helpless animals and charity homes. Then 
the rest for yourself and your family. I will inform you on how 
to share it all.

Please for further information contact me ASAP.

Regards,
Leona Dickmann

[GridSim-users] Gridsim: Error in sending messages from multiple senders to a receiver

[Neetesh S. <nee...@ii...>]

I'm using network flow example (example01), in which 4 users, 2 sender, say
user-1 and user-2 send messages to 2 receiver, say user-3 and user-4.

user-1 -> user-3 (msg)
user-3 -> user-1 (ack)
user-2 -> user-4 (msg)
user-4 -> user-2 (ack)

Now I want to connect new user5 -> user1 (msg) and user-1 -> user5 (ack).
Here is the code, I'm trying:

int num_user = 6;Router r1 = new FlowRouter("router1", trace_flag);
// router 1Router r2 = new FlowRouter("router2", trace_flag);   //
router 2
String sender1 = "user1";String receipient1 = "user3";String sender2 =
"user2";String receipient2 = "user4";
// these entities are the sendersFlowNetUser user1 = new
FlowNetUser(sender1, receipient2, 5.0);FlowNetUser user2 = new
FlowNetUser(sender2, receipient1, 20.0);
String sender3 = "user5";String receipient3 = "user6";FlowNetUser
user5 = new FlowNetUser(sender3, receipient1, 50.0);
// these entities are the receipientsFlowTest user3 = new
FlowTest(receipient1, sender2);FlowTest user4 = new
FlowTest(receipient2, sender1);
// The schedulers are redundent and will be stripped out
soonFIFOScheduler userSched1 = new FIFOScheduler("NetUserSched_0");
r1.attachHost(user1, userSched1);
FIFOScheduler userSched2 = new FIFOScheduler("NetUserSched_1");
r1.attachHost(user2, userSched2);
FIFOScheduler userSched3 = new FIFOScheduler("FlowTestSched_0");
r2.attachHost(user3, userSched3);
FIFOScheduler userSched4 = new FIFOScheduler("FlowTestSched_1");
r2.attachHost(user4, userSched4;
FlowTest user6 = new FlowTest(receipient1, sender3);FIFOScheduler
userSched5 = new FIFOScheduler("NetUserSched_2");FIFOScheduler
userSched6 = new FIFOScheduler("FlowTestSched_2");
r1.attachHost(user5, userSched3);
r2.attachHost(user6, testSched3);
double baud_rate = 1572864; // bits/secdouble propDelay = 300;   int
mtu = Integer.MAX_VALUE;;
Link link = new FlowLink("r1_r2_link", baud_rate, propDelay,
mtu);FIFOScheduler r1Sched = new
FIFOScheduler("r1_Sched");FIFOScheduler r2Sched = new
FIFOScheduler("r2_Sched");
r1.attachRouter(r2, link, r1Sched, r2Sched);



However, when I wish to connect
user-1 -> user-5 (msg) and
user-5 -> user-1 (ack),
the program throws NullPointerException.

java.lang.NullPointerException
    at gridsim.net.flow.FlowRouter.dequeue(Unknown Source)
    at gridsim.net.flow.FlowRouter.processInternalEvent(Unknown Source)
    at gridsim.net.flow.FlowRouter.processEvent(Unknown Source)
    at gridsim.net.Router.body(Unknown Source)
    at eduni.simjava.Sim_entity.run(Sim_entity.java:605)


I wish to know how to do the same. I think there is some problem related to
scheduler. But i'm not able to figure out.
I hope you could help me.

Thanks.

[GridSim-users] Help regarding Gridsim: peer communication

[Neetesh S. <nee...@ii...>]

Hi,

I'm a new user to the Gridsim, and currently wish to use it for my work. I
wish to connect users (say 2) through a router. I followed example01 (sends
pkt directly from sender to recipient), and included one router, attach it
with both users. But I don't know how to start communication between both
entities through router. It returns null values. On the other hand, when I
use "link.attach", both users bypass the router and directly communicate.

Example03 works fine but sends msg from users to the resource, but not to
peer user.
I hope you could help me to sort out this issue.

Any help in this regard would be highly appreciated.

Thanks.

[GridSim-users] Help using GridSim

[prabhdeep s. <pra...@gm...>]

Hello,

I am trying to use the GridSim library to implement my algorithm and want
to compare it to older algorithms. I am having trouble with implementation.
Can someone please refer to an existing implementation for an algorithm,
like the "Conservative Time Optimization" in the paper "THE NIMROD/G GRID
RESOURCE BROKER FOR ECONOMICS-BASED SCHEDULING" by "RAJKUMAR BUYYA AND
DAVID ABRAMSON", since this is the closest to my algorithm.

If not available, can I get implementation of the closest possible
algorithm with a reference to the paper.

Thanks.

[GridSim-users] Technical help reqd

[Rupali K. <rup...@re...>]

Dear sir/Madam..



I have downloaded GridSim however I am not sure whether it is a perfect simulator 

suitable for my problem. Can you comment/guide on this?



My work is as below:



I have java code that reads a database (.CSV) and generates output. Now I need to 

test how my code will behave when the data in CSV + code is distributed to multiple 

systems. One will be controller system which will gather answers from all systems 

and generate final answer.



So does this simulator suitable for me? Or what simulator should I use?



Looking forward to your reply.

With Warm Regards, Rupali. 



May Joy Be With You !!

[GridSim-users] Simulating Data Transfer in GridSim

[Anindya T. <mt...@vi...>]

Dear All,

I was wondering if there is any way to simulate data transfer in GridSim.
As often in the case for grids, the input data is quite huge and it takes a
significant time for the data to reach the execution environment from the
data source.
