Hi Chao, By now, I have no idea on what is happening. So, could you tell me how you create your entities? There may be something wrong whit it. BTW, could you please include the mailing list in your emails? This way, emails will be recorded, and anybody can use them in the future.

Hi, Agustin
My entities are created as following:
1) I changed the RegionalGISWithFailure class to make it can replay failures
for GridResourceWithFailure from log.
2) I create a RegionalGISWithFailure and a SimpleLink as following
Link link = new SimpleLink("rc_link", baud_rate, propDelay, mtu)
RegionalGISWithFailure gis = new RegionalGISWithFailure("GIS", link,
logFile);
3) I create GridResourceWithFailure, and call setRegionalGIS(gis)
Do you think above details are enough?
BTW: I read the examples for GridSimWithFailure, where no Gridsim.setGIS()
is invoked. So I am not sure how I can let GridSim know which is GIS?
Regards,
Chao

You don't have to call Gridsim.setGIS(), I don't know when it is needed,
but it's not needed for the resource faulure functionality.
You can ask Anthony when that function is needed.
Gridsim will always have a system GIS, and apart from that, we have
another GIS.
This second GIS is a regional GIS, and there may be several of them in
each topology.
I think that the function Gridsim.setGIS() is to modify the system GIS,
so not needed for us.
I still don't know what is happening. So, could you send me the file
where you create entities?
Regards,
Agustin
