This page is mostly a record of the steps needed to install CCSM3 on the General Purpose Cluster (GPC) (Linux). This may be useful for running the model through it's initialization step, if for example, you want to change the boundary conditions and need to see if the model initializes with the new boundary conditions.

The first several lines of the Macros.Linux (configuration) file (Using Intel Fortran Compilers):

Modified these files:

run.linux.gpc added:

mpirun -np $NTASKS[1] ./$COMPONENTS[1] : -np $NTASKS[2] ./$COMPONENTS[2] : -np $NTASKS[3] ./$COMPONENTS[3] : -np $NTASKS[4] ./$COMPONENTS[4] : -np $NTASKS[5] ./$COMPONENTS[5]

batch.linux.gpc Mirrored the other linux batch config file, you may need to change in your run script after the model is built

#! /bin/csh -f
#===============================================================================
#  This is a CCSM batch job script for $mach

env.linux.gpc

# General machine specific environment variables  - edit before the initial build
# -------------------------------------------------------------------------

setenv LIB_NETCDF $SCINET_NETCDF_LIB

setenv SCRATCH /scratch/$USER/

if !($?SCRATCH) then
  set SCRATCH = $HOME
  echo "## Warning: SCRATCH not defined in system environment. Set SCRATCH to be $HOME";
endif

setenv EXEROOT             $SCRATCH/exe/$CASE
setenv RUNROOT             $EXEROOT
setenv GMAKE_J             1

#####set the path for netcdf module: netcdf.mod

   ##### user need to set this variable.

setenv DIN_LOC_ROOT_USER   /project/ccsm/inputdata_user

Modified check_machine to include gpc:

/project/ccsm/ccsm3_current/scripts/ccsm_utils/Tools/check_machine

Changed:

/project/ccsm/ccsm3_current/scripts/ccsm_utils/Components/esmf.buildlib

diff esmf.buildlib esmf.buildlib~

24c24
< if ($OS == 'Linux')        setenv ESMF_ARCH linux_intel
---
> if ($OS == 'Linux')        setenv ESMF_ARCH linux_pgi

Edit /project/ccsm/ccsm3_current/scripts/ccsm_utils/Components/mct.buildlib

MCT configure wants to grab gfortran because of the PATH order

if ( `uname` == "Linux" ) then
    setenv FC mpif90
endif

Finally make sure the following modules are loaded: intel, intelmpi, netcdf4.0.1_nc3, gcc

I have the following set on GPC:

 Currently Loaded Modulefiles:

 1) intel/intel-v11.1.072     3) gcc/4.4.0                 5) netcdf/4.0.1_nc3_intel    7) parallel-netcdf/1.1.1
 2) intelmpi/impi-4.0.0.027   4) Xlibraries/X11-64         6) python/2.6.2

My .bashrc has:

if [ "${HOST}" == "AIX" ]; then

 # do things for the TCS machine
 :

else

 # do things for the GPC machine
 module load intel intelmpi gcc Xlibraries netcdf python parallel-netcdf
 export MACH="gpc"
 export PATH="/home/$LOGNAME/bin:$PATH:/scinet/gpc/bin"
 :

fi

My PATH is: /home/guido/bin:/scinet/gpc/Libraries/parallel-netcdf-1.1.1/bin:/scinet/gpc/tools/Python/Python262/bin:/scinet/gpc/compilers/gcc/bin/:/scinet/gpc/intel/impi/4.0.0.027/bin64/:/scinet/gpc/intel/Compiler/11.1/072/bin/intel64/:/usr/lib64/qt-3.3/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/lpp/mmfs/bin:/opt/torque/bin:/opt/torque/sbin:/usr/lpp/mmfs/bin:/opt/torque/bin:/opt/torque/sbin:/scinet/gpc/x11/bin:/scinet/gpc/Libraries/netcdf-4.0.1_nc3_intel/bin:/scinet/gpc/bin
