"I can't upgrade Open MPI on the computing nodes of this system" is false.
Open-MPI can be installed entirely in userspace in your home directory.
If you read the MPI_Comm_create_group paper, there should be instructions
on how to implement this using MPI-2 features. Jim Dinan wrote a working

Is there a combination of MCA parameters
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=
unless you plan to scale on thousands of nodes, you should

contains many calls to MPI functions. When I try to 'make' this code on the
cluster, the only error that I get is "undefined reference to
