MPI_Comm_create_group was not available in Open MPI v1.6. so unless you are willing to create your own subroutine in your application, you'd rather upgrade to Open MPI v2
i recomment you configure Open MPI with --disable-dlopen --prefix=<a shared filesystem available on frontend and compute nodes> unless you plan to scale on thousands of nodes, you should be just fine with that.
