 +The "n79 perf" column are the results after I create a tuned profile named "performance" and then switch to that profile using ''tuned-adm'' and echo the string "performance" in relevant ''/sys'' files.  Also **does not matter** if I run the lmp_mpi version (compiled on ''greentail'') or lmp_mpi-n79 (compiled on ''n79'').  Yea. 
 + 
 +The ""n79 hpc-perf" column are the results after I splice the ''/usr/lib/tuned/hpc-compute/tuned.conf'' settings into my "performance" profile above. Contains a lot of memory settings.  We swap out "throughput-performance" for "latency-performance" and make sure the section ''[cpu]'' still points to performance.
