I use the following command to run the program:
mpiexec -n 4 -hostfile ~/machines release/apps/experiment/mshortestpath --graph /grid/0/j/dataset/twitter_input.
There are 8 nodes in machines.
But the log has following msg: WARNING: dc.cpp(init:587): Duplicate IP address: 10.0.10.161 WARNING: dc.cpp(init:592): For maximum performance, GraphLab strongly prefers running just one process per machine.
Does this means that the program runs on a single node?
