29 November 2005 - Perturbation growth simulation.

source code: CAM-3.1 public distribution

platform: NCAR-bluesky (IBM POWER4 cluster 1600)
uname -a: AIX AIX bs1201en 1 5 0023F7EA4C00
fortran : xlfrte 8.1.1.6

CAM configuration:

% configure -res 48x96 -pergro -spmd -smp

Control run:

The parallel configuration is hybrid mpi/omp.  The run was done using 2
nodes (8-way LPARS) with 2 tasks per node, and 4 threads per task.

% build-namelist -case p0 \
   -namelist "&camexp nsrest=0 nelapse=-2 mss_irt=0 nrefrq=0 \
     nhtfrq=1 ndens=1 mfilt=145 hfilename_spec='h%t.nc' \
     empty_htapes=.true. fincl1='T:I','PS:I' aqua_planet=.true.  /"

The history file was renamed to e48ph_ibm_p0.nc.

Perturbation run:

% build-namelist -case p1 \
   -namelist "&camexp nsrest=0 nelapse=-2 mss_irt=0 nrefrq=0 \
     nhtfrq=1 ndens=1 mfilt=145 hfilename_spec='h%t.nc' \
     empty_htapes=.true. fincl1='T:I','PS:I' aqua_planet=.true. 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_e48ph_ibm_aqpgro.
