Re: [GridSim-users] [GridSim-developers] simulation fails(OOME)with 1000 resources

[Anthony S. <an...@cs...>]

GridSim uses SimJava2 not 1.2!
I specifically label the jar file to simjava2.jar for this reason.
That's why in the SimJava2, it has the distribution package.
Also, according to the SimJava2 report, the underlying simulation kernel
has changed. I can't remember exactly what the changes are.

No, GridSim doesn't modify any of existing SimJava2 classes.
GridSim only takes the class files.
Hence, only the jar file is included not the SimJava2 source files.
