runoff_to_ocn

[cyoo@ewha_ac_kr]

Dear CESM developers: Is there a guideline for how to compile runoff_to_ocn under cesm1_1_1/mapping/gen_mapping_files? The default set up is done for bluefire. I was wondering if I could use some helps. Any comments would be very much appreciated.

Hi there,Before you can build, you need to do two things:

1. Define a
   

   Macros

   file in the
   

   gen_mapping_files/runoff_to_ocn/src/

   directory (see example below). The easiest way is to run
   

   $CCSMROOT/scripts/ccsm_utils/Machines /configure -mach [machine name]

   and then make a few changes
   1. Change the variables
      

      SCC

      ,
      

      SCXX

      , and
      

      SFC

      to
      

      CC

      ,
      

      CXX

      , and
      

      FC

      , respectively
   2. Add the variables
      

      CPP:= [your preprocessor... for intel, use fpp]

      and
      

      CPPFLAGS:= [preprocessor flags... for intel, use -p]

   3. Add
      

      -c

      argument to variables
      

      CFLAGS

      and
      

      FFLAGS

   4. Add the lines
      

      INCLDIR := -I$(NETCDF_PATH)/include

      
      
      

      SLIBS := -L$(NETCDF_PATH)/lib -lnetcdf -lblas -llapack<br />

      to the bottom of the file (anywhere after where
      

      $NETCDF_PATH

      is defined)
2. Make a file similar to
   

   runoff_to_ocn/build.bluefire.csh

   that uses your new
   

   Macros

   file instead of Macros.bluefire in line 23 (the gmake line)

Here is the text of the Macros file used on yellowstone in the upcoming CESM 1.2. Note that

$(NETCDF)

is already an environment variable so we skip setting

$(NETCDF_PATH)

:

CC := mpicc
#CPP := /usr/bin/cpp
CPP := fpp
CPPFLAGS := -P
CPPDEFS :=  -DLINUX
CFLAGS:= -c -O2
FIXEDFLAGS:= -132 
FREEFLAGS:= -FR 
FC := ifort
FFLAGS := -c -O2 -assume byterecl -ftz -traceback
MOD_SUFFIX := mod
LD := $(FC)
AR := ar
INCLDIR := -I. -I$(NETCDF)/include
SLIBS := -L$(NETCDF)/lib -lnetcdf -L/glade/apps/opt/lib
ULIBS :=

ifeq ($(THREAD), TRUE) 
   LDFLAGS += -openmp 
   CFLAGS += -openmp 
   FFLAGS += -openmp 
endif

ifeq ($(DEBUG), TRUE) 
   CPPDEFS  += -DNO_SHR_VMATH
   FFLAGS += -g -CU -check pointers -fpe0 -ftz 
else
   # SLIBS    += -lmass -lmassv -llapack -lblas
   SLIBS    += -llapack -lblas
endif

edit (May 15, 2013): I forgot to add the -llapack and -lblas to SLIB in my example above. You may also need -L$(PATH_TO_BLAS) and -L$(PATH_TO_LAPACK)

Dear mlevy,I appreciate your guidance, but I am still having trouble compiling the code. It appears the code has some errors, if I am not doing something wrong. Here are the errors that I have encountered.1) map_mod.f90(2736): error #6222: This IMPLICIT statement is not positioned correctly within the scoping unit.   implicit none---> This was remedied by moving the "implicit none" to a proper position.2) mapsort_mod.f90(352): error #6633: The type of the actual argument differs from the type of the dummy argument.      call mapsort_qsortRC(map%s(n:m),map%row(n:m),map%col(n:m))----------------------------^mapsort_mod.f90(566): error #6633: The type of the actual argument differs from the type of the dummy argument.            call mapsort_QsortC(map%s(n:m),map%row(n:m),map%col(n:m))---------------------------------^mapsort_mod.f90(1012): error #6795: The target must be of the same type and kind type parameters as the pointer.      S   => map%s---> I do not know how to fix this error. I'd appreciate your input again.

Hi cyoo, The version of the runoff_to_ocn executable distributed with CESM 1.1 and CESM 1.1.1 was tailored to a specific computer, and a lot of shortcuts were taken with regards to compiler flags and such. The version that will be released with CESM 1.2 is much more flexible - I've made it available on the web at http://www.cesm.ucar.edu/models/cesm1.1/mapping/known_problem_fixes/runoff_to_ocn.tar.gz
If you download the above tarball and replace the entire runoff_to_ocn/ directory with the version above, I believe the steps listed in my previous response will be sufficient for you. I tested this version on a machine here, and the only difference I found was that I needed to add "-lnetcdff" to the SLIBS as well:
SLIBS:= -L$(NETCDF_PATH)/lib -lnetcdf -lnetcdff

Thank you very much.
