With the guardness on the web (, I follows these steps. Then I tired to run the pagerank algorithm with following command: mpiexec -n 2 -hostfile ~/machines ~/graphlab/debug/toolkits/graph_analytics/pagerank --graph=test.adj with no responce.

Even I run the wrong command with pageranks instead, I still get no reply. I deploy my graghlab on the cloud platform with ubuntu 12.04 ,64bit

And the command: cat machines is

More: it runs well with command: mpiexec -n 1 -hostfile ~/machines ~/graphlab/debug/toolkits/graph_analytics/pagerank --graph=test.adj

I suspect MPI fails silently on the 2nd machine. Can you try running an MPI command which is not related to Graphlab, for example: mpiexec -n 2 -hostfile ~/machines ls

Does the two machines have similar configuration? Can you run pagerank using a single MPI node on the other machine?
