Hi, Marcos: I am working on GridSim4.1. By the way, it also seems RegionalGIS has some special requirement on the policy used on GridResource, I am using a self-defined policy extended from AllocPolicy, but the resources could not be recognized by RegionalGIS. It seems I need to re-check my own policy class carefully :-p Regards ye On 31 Dec, 2008, at 7:12 AM, Marcos Dias de Assuncao wrote: > > Hi Ye, > > What version of GridSim are you using? > I think I have come against this bug a while ago and I remember of > fixing the GridSim version available at the trunk of the svn > repository.
