ExtendedSSSP example

[Le-Duc Tung]

Hi Semih,

I tried to run the extendedsssp example with a directed acyclic graph.

First, there was an error that the ExtendedSSSPMaster class has missed a constructor, so I added one for it like this

public ExtendedSSSPMaster(CommandLine line) {
        super(line);
}

Then, the example ran without a termination, the number of superstep is continuously increased.

Do you have any idea about this error?

Regards,
Tung.

Hi Tung,

I'm not sure. Somehow the phase is not moving to AVERAGE_COMPUTATION_STAGE. So for some reason, maybe for some reason in your input graph, the stage is probably remaining in SSSP_LATER_SUPERSTEP. I'd try to put println statements to see which vertices are still active after say 100th superstep and try to understand why they're not halting.

Hope this helps,

semih
