Re: [GridSim-users] FW: questions regarding GridSim

[Marcos D. de A. <ma...@cs...>]

Hi Sana,

First, you don't need to call me sir; please use only my first name, Marcos.

Second, regarding you question, GridSim does not provide features to
simulate the distributed checkpointing you need. It is possible to
implement that, but I believe it would not be trivial. Some allocation
policies allow you to pause the execution of Gridlets. For example,
please have a loot at the SpaceShared policy. The pause method can
provide the basic framework you need to implement the more
sophisticated features you require.

About your code, you can post excerpts of it in the GridSim mailing
list along with your questions. In this way, the current GridSim
developers would be able to help you.

Regards,

Marcos
