27 June 2014 - Perturbation growth simulation.

source code: CAM-5.1 (CESM-1.0.6)

platform: NCAR-yellowstone (IBM iDataPlex w/ Intel Sandy Bridge processors)
uname -a: Linux yslogin3 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux
fortran : ifort (IFORT) 12.1.5 20120612

CAM configuration:

% configure -dyn fv -hgrid 1.9x2.5 -ntasks 16 -nthreads 2 -phys cam4 -ocn aquaplanet -pergro

Control run:

The parallel configuration is hybrid mpi/omp.  The run was done using 1
node (16 cores w/ hyperthreading) with 16 tasks per node, and 2 threads per task.

% build-namelist -s -runtype startup \
 -namelist "&camexp stop_option='ndays', stop_n=2 nhtfrq=1 ndens=1 \
   mfilt=97 hfilename_spec='h%t.nc' empty_htapes=.true. \
   fincl1='T:I','PS:I' /"

The history file was renamed to f19c4aqpgro_cam51_ys_intel.nc

Perturbation run:

% build-namelist -s -runtype startup \
 -namelist "&camexp stop_option='ndays', stop_n=2 nhtfrq=1 ndens=1 \
   mfilt=97 hfilename_spec='h%t.nc' empty_htapes=.true. \
   fincl1='T:I','PS:I' pertlim=1.e-14 /"

The RMS temperature differences between the control and perturbation runs
were generated by the utility cprncdf, and written to the output file
RMST_f19c4aqpgro_cam51_ys_intel.
