neurogrid-simulation — For discussion of neurogrid simulator issues and general p2p network simulation

[Neurogrid-simulation] can I simulate this concept in neurogrid simulator ?

[Umer Q <ni...@gm...>]

Hi ,
     I am trying for simulation of a IEEE 2010 p2p paper - "   IRM:
Integrated File Replication and Consistency Maintenance in P2P Systems " by
Haiying Shen . I would like to know if this can be achieved by neurogrid
simulator. The concept goes like this :

Basically, each node actively decides to create a  replica ( based on 2
parameters , if query initating rate (QIR)   > threshold value  replicate at
requester node , if query forwarding rate (QFR) > threshold value  ,
replicate at the junction node ) , delete a replica ( if QIR goes below the
threshold , delete the replica which is at requester node and if QFR goes
below the threshold , delete the replica which is at junction node ) and to
poll for update  based on  file query rate (QIR)  and file update rate . All
this happens dynamically

Is it possible to simulate the above concept using neurogrid ? please
someone give me an answer .

Introduction
Grid computing is the next generation information technology 
infrastructure that promises to transform the way organizations and 
individuals compute, communicate and collaborate. Grid computing is an 
evolution of distributed computing and it refers to a large-scale 
high-performance computing which combines distributed heterogeneous 
computing resources and the result is a unique large virtual 
supercomputer with a vast amount of shared processing power and data 
storage. Considering the enormous amount of these underutilized 
computing resources, the necessity of a grid infrastructure is 
compulsory. A computational grid provides access to users who want to 
utilize the shared processing resources in order to efficiently apply 
high throughput applications on distributed machines. The second most 
common shared resource used in a grid is data storage and it is known as 
data grid. This type of grid provides distributed storage capacity such 
as attached memory to the processor, hard disk drives or other types of 
permanent storage. Grid computing can assist grid users in order to 
utilize to the maximum computing resources by applying tasks and solving 
a scientific or technical problem that requires a great number of 
computer processing cycles or the need to process large amounts of data.

Objective of the Book
This book aims to provide relevant theoretical frameworks and will cover 
the latest empirical research findings in the area of grid computing. 
The goal of this book is to represent theoretical frameworks, 
methodologies, implementations, and cutting edge research findings with 
a critical perspective bridging the gap between academia and the latest 
achievements of the computer industry. It will be written for 
professionals, as well as students, who are involved or interested in 
the study, use, design, and development of grid computing and want to 
improve and empower their understanding of it. Also, this book aims to 
help researchers and developers understand the basics of the field, to 
highlight the various developments over the years in the field by giving 
an in depth analysis of grid networks.

Target Audience
The target audience of this book will be composed of professionals, 
engineers, researchers and students who are interested and working in 
the field of grid computing. Moreover, the book will provide insights 
and can serve as both literature at an undergraduate level and as an 
overview of the area.

Recommended topics include, but are not limited to, the following:
1.Theories, definitions, methodologies, models, applications, 
simulations, and architectures relevantto grid computing
2.Implementations of computational grids, data grids, sensor and mobile 
grids
3.Grid data storage, grid databases, data management, and data mining
4.Indexing and query optimization over grid databases

hello,teacher.
I'm a begginner of the Neurogird.My system is windows xp.I have installed jdk1.6 ,ant1.7.1 and tomcat6.0.I download the ng-simulator_0.2.1 and follow the NeuroGrid Installation Manual,but i can't find the WEB-INF folder in the build folder after running ant.
what's wrong?
THANKS. 

Re: [Neurogrid-simulation] a little question...

[Sam J. <sa...@ne...>]

Hi Slawek,

I think you might find the answer you need in the documentation:

http://www.neurogrid.net/twiki/bin/view/Main/PeerToPeerSimulation

http://www.neurogrid.net/twiki/bin/view/Main/SimulationParameters

I'm afraid I am not actively supporting the neurogrid simulator at 
present, so I can't speak to the efficiency of using it.

I recommend reading some of the latest papers on developments in the p2p 
simulation field (see attached)

Re: [Neurogrid-simulation] Forwarding an Injected message with Gnutella

[Sam J. <sa...@ne...>]

Hi Robert,

I'm sorry no one has gotten back to you sooner.

As I have mentioned it has been some time since I looked at the code, 
but  the approach you are using doesn't work because the previous node 
is set to the start node in Network.java method searchNetwork.

A more effective way to check would be to compare the start node to the 
previous node, since they will only be equal when the node is at the 
start node.  Ideally you would add a helper method to the message class 
to support this.

if p_message.getPreviousLocation() == p_message.getStart()

[Neurogrid-simulation] Forwarding an Injected message with Gnutella

[Robert C. M. I. <mos...@ms...>]

I'm trying to modify the Gnutella protocol to act differently when it
first generates/injects a node then when it passes a node along.
Basically it is a k-walker where the first node sends out k-copies of
the message randomly, than all receiving nodes just pass one copy to a
random node.

The problem I am having is my check for whether this is the start node.
I thought "if (x_previous != null)" would work, as it is used when
checking whether to remove a message from a prior node. However this
check is always true. What would be the proper way to check whether a
message is injected or handled from the forwardMessage() function in
GnutellaMessageHandler.java?

Thanks,
Rob Mosher

Re: [Neurogrid-simulation] NeuroGrid stats

[Thomas R. <tr...@cs...>]

Hi Robert,

I am attaching a sample parameters file.  And you run the simulator like
this:

./ant/bin/ant simulation-stat
-Dfile=conf/adp_ADVANCED_GNUTELLA.properties

You can let us know if you still have problems.

Re: [Neurogrid-simulation] NeuroGrid stats

[Sam J. <sa...@ne...>]

Hi Robert,

I'm afraid I'm not immediately sure why the logging isn't working.  I 
haven't used the NeuroGrid simulator myself since 2005.  My own research 
has moved away from network simulation, although it has started to move 
back in that direction, and I just wrote a new basic simulator in Ruby 
(which is a much friendlier language than Java).

I just took a look at the code, and the parameters file you have looks 
good, so I can't immediately see why you would not be getting that 
output, unless you are running a basic simulation instead of an advanced 
simulation.  I think that the additional log files are only used in 
advanced simulations.  I think you need to run ant.bat simulation-stat 
as described here:

http://www.neurogrid.net/twiki/bin/view/Main/GnutellaSimulation

The neurogrid-simulation mailing list is probably the best place to ask 
additional questions, as I will get those emails and so potentially will 
others using the system. However you need to subscribe to the mailing 
list, as there is so much spam sent to it I have it set to only accept 
mail from subscribers.  I believe you can join the mailing list here:

https://lists.sourceforge.net/lists/listinfo/neurogrid-simulation

However you might want to read an excellent paper that compares the 
range of different P2P simulators available today:

[Neurogrid-simulation] Re: I hava a question about neurogrid simulator

[Sam J. <ga...@yh...>]

Hi Soohong,

Sorry for the delay in getting back to you. I'm afraid I haven't had
time to work on the simulator for over a year and don't anticipate being
able to work on it for at least another year :-( Sorry about that.

The warning message you are getting is not a problem - just a logging
configuration message. The results of the simulation will be stored to
disk in the output folder.

There is much documentation in the wiki:

http://www.neurogrid.net/twiki/bin/view/Main/PeerToPeerSimulation

You may also be able to find help on the mailing list I am cc-ing this
message to.

The 0.2.1 package does have errors, and you main find that the version
in CVS (available from sourceforge) has more of what you need.

Unfortunately my work prevents me from properly supporting the simulator
at present.

Apologies

hi jamie,

I'm afraid I haven't had any time recently to work on the system.  The 
simulator does not use tomcat at all.

Much information is in the wiki:

Hi Shuli,=20

have you made sure that the simulation runs and the traces are=20
generated correcly?  This page should help you out: =20

http://www.neurogrid.net/twiki/bin/view/Main/GnutellaSimulation

Also, most importantly, iirc the simulator version you can download=20
from the website does not contain a "chart" target in the build.xml file. =

Furthermore some of the different configuration files are not functioning=

Hello Dr. Joseph and the Neurogrid Simulator team,

My name is Shuli.  I am currently a 4th year Computer Science
undergraduate at UC Irvine.  I have been exploring the Neurogrid Simulator
for a while now but am having trouble initiating the chart generation
feature.

I am currently using version 0.2.1 ng-simulator.

From what I have gathered, the following command is not supported in the
build.xml file:

ant.bat chart -Dfile=[outputfilename].log


Perhaps I am overlooking something important.  Could you help and point me
in the right direction? Thank you all very much.

Hi Hildiene,

I'm afraid that the Freenet simulation component has bot been fully

http://www.neurogrid.net/twiki/bin/view/Main/PeerToPeerSimulation
or by asking on the neurogrid-simulation mailing list.  People have been 
asking about Freenet simulation and I believe I explained the situation 
to them on the mailing list - you can access the mailing list archives at:

http://lists.sourceforge.net/lists/listinfo/neurogrid-simulation
http://sourceforge.net/mailarchive/forum.php?forum=neurogrid-simulation

I think your options are to try and implement Freenet in the latest 
version or try to access an older version which contained the working 
Freenet simulation.

I'm sorry I can't help you more at the moment, I'm very busy with other 
projects.   I hope to have more time to put into the simulator next year.

Best of luck.

[Thomas R. <tr...@cs...>]

Hi Yun,=20

I'm not sure how multi-chart currently works, if at all. =20
You can however create some chart by simply running a simulation, e.g.: =20

=2E/ant/bin/ant simulation -Dfile=3Dconf/ADVANCED_GNUTELLA.properties

Hope this helps.

Cheers!

Hi Yun

Sorry to take so long to get back to you - so busy with other projects
now - and work at University of Hawaii that I haven't had time to think
about the simulator for a while - hope to sometime next year.

I'm cc-ing this email to the neurogrid simulation list in the hope that

Re: [Neurogrid-simulation] Neurogrid Simulator Question

Hi Thomas,=20

I would suggest you use the cvs version of the simulator. =20
The download is straightforward and well documented both=20
in sourceforge and in the wiki, e.g.:
http://www.neurogrid.net/twiki/bin/view/Main/UsingCVS
http://sourceforge.net/cvs/?group_id=3D26907

[Neurogrid-simulation] Neurogrid Simulator Question

[Thomas C. <tc...@ic...>]

Hi,

1. I'm using the Neurogrid Simulator version 0.2.1 and the commands in 
the Read_Me document, mores specifically the

/java -classpath .:../lib/log4j-1.1.3.jar 
com.neurogrid.simulation.AdvancedSimulation 
./../ADVANCED_PARAMETERS.properties/

command doesn't work for my set up. I have j2sdk1.4.2_05 and type the 
previously stated command in the build directory of the simulator 
directory. It gives me this error:

/Exception in thread "main "java.lang.NoClassDefFoundError: 
com/neurogrid/simulation/Simulation

/I am not sure if the documentation in the Read_Me is outdated (the one 
in the TIKI documentation appears to be more updated, but doesn't give 
the command to run a simulation with different parameters).



2. Bypassing the command-line error, I could simply rename the 
conf.properties that I need to use and call it PARAMTERS.properties, but 
when I do this and run "ant.bat simulation" I get errors regarding the 
log4j, namely an appenders error and initialization error:

/log4j:ERROR No appender could be found for category 
(com.neurogrid.simulation.root.Keyword).
log4j.ERROR Please initialize the log4j system properly

/I am using the default configuration settings for version 0.2.1.

Re: [Neurogrid-simulation] Question about support for Pastry

[Sam J. <ga...@yh...>]

Hi Chatree,

A version of Pastry was implemented within the neurogrid simulator, 
however it is part of the DistributedEmailSimulation code:

http://www.neurogrid.net/twiki/bin/view/Main/DistributedEmailSimulation

and not really set up quite the way to make it wonderfully easy to 
modify/play-with.

One outstanding job is to try and get the Pastry routing set up to work 
with the MessageHandler classes so that it fits in with the other 
protocols in the simulator.  If you were interested in doing this I 
would give you all the help I can.

The existing code is in the com/neurogrid/simulation/email/ directory, 
but it might be easier to start from scratch.

[Neurogrid-simulation] Question about support for Pastry

[Chatree S. <ch...@cs...>]

Hi,

I am trying to find a generic p2p simulator that can simulate behaviors of
unstructured p2p, like neurogrid and structured p2p, i.e pastry.

Some of your documents mentioned about the support for pastry. However,
you do not include that in the simulation parameters.

Could you please let me know whether your simulator support it? or do I
need to write an extention class by myself?

Regards,
Chatree Sangpachatanaruk
