[GridSim-developers] need help in GridSim code

[SANA M. <dua...@ho...>]

Hi everyone,

i am doing a grid computing project, currently i am facing following problems, my code is attached here with the mail.


firstly, i want to pause gridlets to take a checkpoint of their executed portion but the state returned is the total length of the gridlets.

how and when should i pause these gridlets to take the checkpoint?

 

secondly, i want to replicate that executed portion on some nodes called checkpoint servers for storage, i studied data grid exemples but the replication done there is of file while i want to replicate data and if i replicate it as a gridlet then the receiving node will start processing on it, there is no built in method for checkpoint replication, can anyone suggest me the way to solve this problem?

 

thirdly, according to my system model grid is constructed of multiple clusters where each cluster (called resource in GridSim) have more than one checkpoint servers and i have to replicate the checkpoint on all of the checkpoint servers, now my question is that can we do such thing in simulation? i mean we define processing entities in resources that process the jobs, how can i just store the data on processing entities? or should i create just one linkedlist for a resource to do the job.

 

looking forward for your kind respons.

best regards

 
Sana Malik
