Run Checklist


Complete the following checklist prior to beginning the production run:



1.  Update status file: /web/web-data/cseg/ccsm4_0_runs/b40.20th.track1.1deg.007/status.txt  [assigned, setup in progress, running]

2.  Document NCAR software levels at beginning of run (use the spinfo command on bluefire)

    Years 1850 - 1967 were compiled and ran with the following software levels:

    Bluefire AIX Technology Level 10 and Service Pack 9.2 upgrade completed Jan

    Please note that the XL Fortran compiler was upgraded from 12.1.0.5 to
    12.1.0.6. It is reccomended that you recompile before you submit your jobs.
 
    Years 1968 - 2005 were recompiled and ran with the following software
    levels.

    Years 1968 - 2005 were recompiled and re-run again due to a the hardware
    floating point problem that requires a work-around in the code generator of
    xlf.  The compiler with the work-around mod was provided by IBM and Jim
    Edwards tested it.  This is how you invoke the compiler with the needed
    mod.   
     
    * please build with the following changes to Macros.bluefire (to
    * remove irreproducibility)

    ifeq ($(USE_MPISERIAL),TRUE)
       FC := xlf90_r
       CC := cc_r
    else
       FC := mpxlf90_r -tb -B/ptmp/jedwards/comppatch/ -qxflag=fixdivsimple
