There is a directory called scripts/tools that contains some supporting scripts. A description of all the scripts in this directory can be found in the CCSM2 User's Guide. Two sets of these scripts are of interest for running the model off site. The first set is modules.*.*. These are machine specific setup scripts that are called by the main script. The second set of scripts is test.a1.mods.*. These files contain notes about how to change the main setup script to get it running on other machines. For example, to run CCSM2 on nirvana at Los Alamos National Laboratory (LANL) see test.a1.mods.nirvana. The following job control language will need to be added to the top of the main script:
#BSUB -L /bin/tcsh #BSUB -n 36 # Specify threads/processes #BSUB -R "span[ptile=36]" # all processors on 1 machine #BSUB -q csmq # Specify queue #BSUB -J test.a1 # Specify the job name
The following environment variables should be changed in the main script:
setenv CSMROOT /users/$LOGNAME/ccsm2 # root directory of source setenv CSMDATA /n/n07/scratch/$LOGNAME/inputdata # base dir for input data setenv EXEROOT /n/n07/scratch/$LOGNAME/$CASE # run model here setenv ARCROOT /n/n07/scratch/$LOGNAME/archive/$CASE # archive root direct set NTASKS = ( 1 1 4 16 1 ) # use NTASK = 1 for data model use NTASK = 1 for data model set NTHRDS = ( 8 2 1 1 2 ) # use NTHRD = 1 for data model use NTHRD = 1 for data model unsetenv _DSM_VERBOSE ; setenv _DSM_PLACEMENT ROUND_ROBIN
It is possible to use the GUI to set up the model to run on an SGI (select SGI under the Select Platform options). More details on the GUI are in section 3.1.
