 2. on multiple machines, you could run GossipMap by using "mpiexec" command.  All of the machines should be installed GraphLab PowerGraph and MPI.
     - [Usage] > mpiexec -f machines /path/to/GossipMap --graph <graph-data> --thresh <threshold> --maxiter <maxIter> --maxspiter <maxSuperIter> --trials <# trials> --mode <1 or 2> --outmode <1 or 2> --ncpus <nCores>

     - 'machines' is a file which contains the hostnames of the machines used for running GossipMap.
-	The command will generate 1 process on each machine represented in 'machines' unless specified.
-    If you want to specify the number of MPI processes, you can add '-n <nProcs>' options, such as "mpiexec -n 4 -f machines ..." 
-    We recommend use the number of less than or equal to the number of machines for <nProcs> value when you use '-n' option for better performance.
