Re: [GridSim-users] question on demo of regional gis

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

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. I don't remember which version I fixed at that time.

Regards,

Marcos
