Thanks Prof. Guiling Wang in University of Connecticut for suggesting me to provide a more detail summary of the problems to ICTP 

that I met when I run RegCM4.2 with CLM option.

I totally met seven problems. Six of them were solved (fixed). One is left.

The six problems fixed are listed here:

Also I am sorry that the strange problems were caused on Friday at the workshop by the fixing methods I posted. I do not have the detail of the strange

problems caused and I can not tell. In my end, there is no strange problems except the one left unsolved.

The following is a more detail summary of the steps for me to compile and run RegCM4.2 with CLM option. 

If you have problems by following the instruction, please feel free to let me know. I am more than happy to help you.

Starting the instruction:

Let say $REGCM_ROOT = “the path where your put the code” and  “>” means UNIX command needed to inout.

 

Step 1: download the RegCM4.2 user guide from http://gforge.ictp.it/gf/download/docmanfileversion/26/569/UserGuide-4.2.pdf

 

Step 2: Read Chapter 3.1 to see software needed to compile and install RegCM4.2

 

Step 3: Read Chapter 9 to see how to install the pre-required software.

FYI: I only installed NETCDF library and OpenMPI library

 

Step 4: Edit .tcshrc (for C shell) in your home directory to define the following shell environment variables according to the compiler on your system

# (Don’t use “ ” in your shell, here I just want to make clear)

setenv  NETCDF            “path of Netcdf Libary”

setenv MPI  “path of Openmpi libary”

set path = ($MPI/bin $path)

# If LD_LIBRARY_PATH is not defined, please define as the following. Otherwise add the Netcdf library and MPI library to previous one

setenv LD_LIBRARY_PATH $NETCDF/lib

setenv LD_LIBRARY_PATH $MPI/lib:$LD_LIBRARY_PATH

 

Step 4: Patch $REGCM_ROOT/configure file to fix the configure can not find NETCDF Library file, MPI library file (mpi.h) and the files in clmlib. 

Download the attached file configure.patch to $REGCM_ROOT, and patch it

> patch –p0 –i configure.patch

 

Step 5: Patch $REGCM_ROOT/Main/ mod_lm_interface.F90 to fix Bug 1 and Bug 3 found here: https://lists.ictp.it/pipermail/regcnet/2012/006083.html

Download the attached file mod_lm_interface.F90.patch and put it in $REGCM_ROOT/Main

> patch -p0 -i mod_lm_interface.F90.patch

 

Step 6: Patch $REGCM_ROOT/PreProc/ICBC/mod_sst_1deg.F90 to fix Bug 2 found here: https://lists.ictp.it/pipermail/regcnet/2012/006083.html

Download the attached file mod_sst_1deg.F90.patch and put it in $REGCM_ROOT/PreProc/ICBC

> patch -p0 -i mod_sst_1deg.F90.patch

 

Step 7: To fix Bug 3 found here: https://lists.ictp.it/pipermail/regcnet/2012/006083.html, you need the following patches:

mod_bats_common.F90.patch

mod_lm_interface.F90.patch  (already used in Step 5)

mod_mtrxclm.F90.patch

surfrdMod.F90.patch

 

Download mod_bats_common.F90.patch and put it in $REGCM_ROOT/Main/batslib

> patch -p0 -i mod_bats_common.F90.patch

 

Download mod_mtrxclm.F90.patch and put it in $REGCM_ROOT/Main/clmlib

> patch -p0 -i mod_mtrxclm.F90.patch

 

Download surfrdMod.F90.patch and put it in $REGCM_ROOT/Main/clmlib/patchset to replace the old one coming with the code.

 

Step 8: To fix Bug 4 in there: https://lists.ictp.it/pipermail/regcnet/2012/006083.html

 

Download clm2rcm.F90.patch and put in $REGCM_ROOT/PreProc/CLM

> patch -p0 -i clm2rcm.F90.patch

 

Step 9: To fix But 5 (CLM can not recognize Gregorian calendar) found there:

https://lists.ictp.it/pipermail/regcnet/2012/006083.html

 

Download clm_time_manager.F90.patch and put it in $REGCM_ROOT/Main/clmlib/patchset to replace the old one

 

Download ESMF.inc.patch and put it in $REGCM_ROOT/Main/clmlib/clm3.5/src/utils/esmf_wrf_timemgr

> patch -p0 -i ESMF.inc.patch

 

If you use no_leap calendar, Please define -DNO_LEAP_CALENDAR in CPPFLAGS during configuration. (I will show you later).

 

Step 10: To fix the bug (segmentation fault caused by reallocation of c2r_allout in clm_atmlnd.F90) found here:

https://lists.ictp.it/pipermail/regcnet/2012/006113.htm

 

Download clm_atmlnd.F90.patch and put it in $REGCM_ROOT/Main/clmlib/patchset to replace the old one

 

Step 11: Run configure

 

> setenv CPPFLAGS '-I/parth_MPI_library/include'

If you use no_leap calendar, use the following one:

> setenv CPPFLAGS '-I/parth_MPI_library/include -DNO_LEAP_CALENDAR'

 

> ./configure --with-netcdf=parth_netcdf_libary --enable-clm

Step 12: make all and make install

 

Step 13: Run RegCM4.2

mpirun -np 10 ./Bin/regcmMPI_clm regcm.in > & std.out &

(you should have regcm.in available)
