Re: [GridSim-users] about GridSim

Dear Andrey,

thank you for your question, I hope I can provide you a satisfactory answer.
I believe the easiest way to start experimenting with the Data Grid 
functionality is to look at the examples, which inlcude a more detailed 
description.
The examples can be found at:
http://www.gridbus.org/gridsim/example/data_index.html

There are various ways how to implement the actions of the users. The 
easiest way is described in Example 4, since no programming is required.
However the actions that one can specify are only:
1. getting a file,
2. getting the attribute of a file,
3. replicate a file and
4. deleting a file.


To implement more complex user behavior you have to implement your own 
users by extending the class DataGridUser. An example of how to do this 
is described in Example 3.

Unfortunately there is no sophisticated way of gathering the statistics 
at the moment. The simplest approach is to simply print on the standard 
output the desired parameters at the desired time. After the simulation 
has finished you can use text manipulation tools (e.g. grep, awk) to 
extract the events from the output for further analysis.

Kind regards,

Uros Cibej
