running with replica exchange on stampede

What is the appropriate command line to use for running with replica exchange on stampede? In particular, I am trying to run 6 replicas, with one node dedicated to each replica. Building off of Jim’s script for the mpi version, I tried

ibrun /work/00288/tg455591/NAMD_build.latest/NAMD_2.10_Linux-x86_64-MVAPICH-Intel-Stampede/namd2 +pemap 0-15 +replicas 6 conffile >& logfile

but this only uses one processor per replica instead of 16. Am I even using the right version? If so, I assume I am missing some additional needed command line options.
