When you use native MPI (as I do on Pelican.lsu.edu in the nightly 
integration tests) then the testsuite run command would be

   CCTK_TESTSUITE_RUN_COMMAND = 'poe $exe $parfile -rmpool 1 -nodes 1 
-tasks_per_node <nprocs>"

For debugging it might be handier though to use an MPICH-ch_shmem 
installation, for instance

   MPI       = MPICH
   MPICH_DIR = /home/tradke/install/mpich-1.1.2

then the command is just the default

   CCTK_TESTSUITE_RUN_COMMAND = 'mpirun -np <nprocs> $exe $parfile'
