Starting with [[GEOS-Chem v8-02-03]], we have modified the directory structure of GEOS-Chem.  Rather than keeping all source code files in a single directory, we now have partitioned source code files into several subdirectories with most subdirectories having their own Makefile. This was done for the following reasons:
+
GEOS-Chem and GCHP use two build systems to compile source code files into an executable file:
  
−
:1. To facilitate the installation of 3rd-party software packages such as:
+
#[[Compiling with GNU Make|GNU Make]]
−
:* [[HEMCO]]
+
#[[Compiling with CMake|CMake]]
−
:* [[Coupling_GEOS-Chem_with_RRTMG|RRTMG radiative transfer model]]
+
−
:* [[KPP solvers FAQ|KPP chemical solver]]
+
−
:* Aerosol microphysics codes (e.g. [[APM_aerosol_microphysics|APM]])
+
−
:* [[ISORROPIA II]]
+
−
:* Terrestrial models (e.g. CASA, [[Global Terrestrial Mercury Model|GTMM]])
+
−
:into GEOS-Chem.  Our guiding principle is that all 3rd-party software packages should be cleanly separable from the main-line GEOS-Chem code.  This will allow the 3rd-party software packages to be updated without having an impact on the rest of the GEOS-Chem source code files.
+
  
−
:2. To simplify the maintenance of the GEOS–Chem code files. Without subdirectories, there would have been hundreds of source code files in a single directory, and it would have been very difficult to keep track of them all.
+
Starting in 13.0.0 both GEOS-Chem "Classic" and GCHP use CMake exclusively.

== Which versions can use GNU Make and which can use CMake? ==

Here we list the directory structure for recent model versions.

=== GEOS-Chem "Classic" compatibility matrix ===
  
−
=== GEOS-Chem v10-01 ===

== Compilation sequence ==
 
−
 
−
GEOS-Chem's makefiles compile source code files in the following order:
 
−
#Files in <tt>NcdfUtil/</tt> (if [[Global_Terrestrial_Mercury_Model|GTMM]] is enabled for the [[Mercury|mercury simulation]])
 
−
#Files in <tt>Headers/</tt>
 
−
#Files in <tt>KPP/</tt>
 
−
#Files in <tt>GeosUtil/</tt>
 
−
#Files in <tt>HEMCO/Core/</tt>
 
−
#Files in <tt>HEMCO/Extensions/</tt>
 
−
#Files in <tt>HEMCO/Interfaces/</tt>
 
−
#Files in <tt>ISOROPIA/</tt>
 
−
#Files in <tt>GeosRad/</tt> (if [[Coupling_GEOS-Chem_with_RRTMG|RRTMG]] is enabled)
 
−
#Files in <tt>GeosCore/</tt>
 
−
 
−
Each of theses directories has its own makefile that contains a list of all of the source code files within the directory, plus dependent routines (a.k.a. the &quot;dependencies&quot; list). Source code files that do not refer to any modules have a dependencies list such as:
 
−
 
−
    decomp.o                    : decomp.F
 
−
 
−
Whereas a source code file that refers to several modules (in this case, <tt>GeosCore/aerosol_mod.F</tt>) has a dependencies list like this:
 
−
 
−
    aerosol_mod.o              : aerosol_mod.F                                  \
 
−
                                  chemgrid_mod.o          comode_mod.o          \
 
−
                                  dao_mod.o              diag_mod.o            \
 
−
                                  tracerid_mod.o          ucx_mod.o
 
−
 
−
Examination of <tt>GeosCore/aerosol_mod.F</tt> reveals that this module refers to many other modules not listed above. However, many of those modules are found in different directories (such as <tt>Headers/</tt> and <tt>GeosUtil/</tt>), which are compiled prior to <tt>GeosCore/</tt>. Therefore you do not need to list those modules when creating the dependencies listing. In the example above, we have only specified the 6 modules that are located in the same directory as <tt>aerosol_mod.F</tt>.
 
−
 
−
The order of modules in the dependencies list does not matter. The [http://www.gnu.org/software/make/ GNU Make] utility will define the order of compilation from the list of files (and their dependencies) that you have specified in each Makefile. You will not have to worry about this unless you add new source code files. If you have questions about how to add dependency lists to makefiles, please let us know.

=== Makefile Options ===
 
−
 
−
To compile GEOS-Chem, you need to be in the top-level code directory. The GEOS-Chem makefiles allow you to choose from several different options.  The best way to learn about these options is to type
 
−
 
−
make help
 
−
 
−
at the Unix prompt.  You will then get a screen similar to this:
 
−
 
−
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
−
%%%      GEOS-Chem Help Screen      %%%
 
−
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
−
 
−
Usage: make -jN TARGET REQUIRED-FLAGS [ OPTIONAL-FLAGS ]
 
−
 
−
-jN            Compiles N files at a time (to reduce compilation time)

=== Specifying compiler flags ===
 
−
 
−
Please keep the following items in mind when specifying compiler flags.
 
−
 
−
*When starting with a new version of GEOS-Chem or a new simulation type you should always issue the following command:
 
−
      make realclean
 
−
:This is especially important if you are changing the met field type or horizontal grid settings. The command will remove all previously-created compiler output files (e.g. *.a, *.o, *.mod) and executables. After doing <tt>make realclean</tt>, you can recompile GEOS–Chem again with your new options.
 
−
* You can speed up compilation by specifying <tt>make -j4</tt> to compile 4 files at a time. If you have more CPUs available you can change this number.
 
−
* You must specify a value for <tt>MET</tt>. Please see out [[Overview_of_GMAO_met_data_products|''Overview of GMAO met data products'' wiki page]] for more information on the meteorology fields.
 
−
** Allowable values are: <tt>geosfp</tt>, <tt>geos5</tt>, <tt>geos4</tt>, <tt>merra</tt>, <tt>gcap</tt>
 
−
* You must specify a value for <tt>GRID</tt>. Please see [http://acmg.seas.harvard.edu/geos/doc/man/appendix_2.html Appendix 2 of the GEOS-Chem User's Guide] for more information on the horizontal grids.
 
−
** Allowable values are: <tt>4x5</tt>, <tt>2x25</tt>, <tt>05x0666</tt>, <tt>025x03125</tt>
 
−
* If you select <tt>GRID=05x0666</tt> or <tt>GRID=025x03125</tt>, then you must select a [[GEOS-Chem_nested_grid_simulations|nested-grid]] option:
 
−
**<tt>NEST=ch</tt> for the China nested grid
 
−
**<tt>NEST=na</tt> for the North America nested grid
 
−
**<tt>NEST=eu</tt> for the Europe nested grid
 
−
**<tt>NEST=se</tt> for the SE Asia nested grid (GEOS-FP only)
 
−
* Makefile target names are case-sensitive. For example, you should type <tt>make all</tt>, not <tt>make ALL</tt>.
 
−
* Makefile flags will accept case-insensitive output. You may omit dashes from met field names. Each of the following is acceptable:
 
−
**<tt>MET=geos5</tt>, <tt>MET=GEOS5</tt>, <tt>MET=Geos5</tt>, <tt>MET=geos-5</tt>, etc.
 
−
* Makefile flags that require a simple yes/no answer will accept case-insensitive input. For example:
 
−
**<tt>DEBUG=yes</tt>, <tt>DEBUG=Yes</tt>, <tt>DEBUG=y</tt>, <tt>DEBUG=No</tt>, <tt>DEBUG=NO</tt>, etc.
 
−
* Some debug compiler flags may slow down your simulation, so we recommend using them for short test simulations only. For more information, see [[#Compile-time_options_that_can_slow_down_GEOS-Chem|this wiki post]].

=== Setting default flags ===
 
−
 
−
The REQUIRED-FLAGS and OPTIONAL-FLAGS can be specified in one of two ways:
 
−
 
−
:1. '''As a command-line argument to the GNU Make utility'''
 
−
::For example, if you wanted to build the GEOS-Chem executable using the [[KPP_solvers_FAQ#Which_KPP_solvers_can_I_use.3F|KPP solver with Rosenbrock integrator]] and the [[Secondary_organic_aerosols|SOA mechanism]] you could type:
 
−
        make -j4 MET=geosfp GRID=4x5 KPPSOLVER=rosenbrock CHEM=SOA
 
−
 
−
:2. '''As an environment variable'''
 
−
::If you don't wish to keep typing KPPSOLVER=rosenbrock CHEM=SOA every time, you could instead use:
 
−
 
−
        setenv KPPSOLVER rosenbrock
 
−
        setenv CHEM      SOA
 
−
        make -j4 MET=geosfp GRID=4x5
 
−
 
−
::Specifying options as environment variables allows you to predefine settings so that you don't have to physically type them on the command line every time you build GEOS-Chem.  The environment variables can also be placed in your <tt>~/.cshrc</tt> or <tt>.bashrc</tt> so that they are initialized when you log in.

--[[User:Melissa Payer|Melissa Sulprizio]] 18:04, 7 April 2015 (EDT)
 
−
 
−
=== Compiling examples ===
 
−
 
−
(1) To build GEOS-Chem executable for the 4x5 grid with [[GEOS-FP]] meteorology, one can simply type:
 
−
 
−
    make -j4 MET=geosfp GRID=4x5
 
−
 
−
(2) To select a different compiler (e.g. PGI), type:
 
−
 
−
    make -j4 MET=geosfp GRID=4x5 COMPILER=pgi
 
−
 
−
<blockquote>
 
−
* Depending on your PGI compiler setup, you may also have to add the option <tt>NONUMA=yes</tt>.
 
−
</blockquote>
 
−
 
−
(3) The default is to compile for multi-processor.  To turn off the parallelization and build the executable for a single-processor, type:
 
−
 
−
    make -j4 MET=geosfp GRID=4x5 OMP=no
 
−
 
−
(4) To compile GEOS-Chem (multi-processor) for use with a debugger (e.g. Totalview), type:
 
−
 
−
    make -j4 MET=geosfp GRID=4x5 DEBUG=yes FPE=yes OMP=yes
 
−
 
−
(5) To compile GEOS-Chem (single-processor) with the same debugging options, type:
 
−
 
−
    make -j4 MET=geosfp GRID=4x5 DEBUG=yes FPE=yes OMP=no
 
−
 
−
(6) To test for [[Common_GEOS-Chem_error_messages#Array-out-of-bounds_error|array-out-of-bounds errors]], type:
 
−
 
−
    make -j4 MET=geosfp GRID=4x5 BOUNDS=yes
 
−
 
−
(7) If you wish to compile the code but not make the executable, you may type:
 
−
 
−
    make -j4 MET=geosfp GRID=4x5 BOUNDS=yes lib
 
−
 
−
(8) To print the GEOS-Chem help screen, type::
 
−
 
−
    make help
 
−
 
−
(9) To generate [http://acmg.seas.harvard.edu/geos/doc/man/chapter_9.html#Reference GEOS-Chem Reference Guide documentation] in PostScript and PDF formats, type:
 
−
 
−
    make doc
 
−
 
−
(10) To remove all <tt>*.o</tt>, <tt>*.mod</tt>, and executable files from the source code directories (but not from the <tt>mod</tt>, <tt>lib</tt>, or <tt>bin</tt> directories), type:
 
−
 
−
    make clean
 
−
 
−
(11) And to remove everything and start over from scratch, type:
 
−
 
−
    make realclean
 
−

=== Advanced compilation techniques ===
 
−
 
−
==== Compiling with Unix shell scripts ====
 
−
 
−
It is possible to write a shell script to compile the GEOS–Chem code, such as the following:
 
−
 
−
    #!/bin/tcsh -f                      # Script definition line
 
−
    cd Code.v9-02                        # your code dir
 
−
    rm -f log                            # clear log file
 
−
    make -j4 MET=geos5 GRID=4x5 > log    # build the code
 
−
    exit(0)                              # exit normally
 
−
 
−
You can then run this script interactively, or submit it to the queue system on your computational cluster.
 
−
 
−
==== Compiling with a run-directory Makefile ====
 
−
 
−
The GNU Make utility is a powerful and flexible software development tool. With a little effort, you can design a Makefile that can be placed into your GEOS–Chem run directory that will create a GEOS–Chem executable and start a simulation. Here is an example:
 
−
 
−
# This makefile is a "router" makefile.  It calls the Makefile
 
−
# in the GEOS-Chem code directory (with various user-supplied options)
 
−
# to build and run the GEOS-Chem model.
 
−
 
−
# Define variables
 
−
SHELL  = /bin/bash
 
−
 
−
# Make the development version "Code" the default directory
 
−
ifndef GEOSDIR
 
−
GEOSDIR = /home/bmy/Code.v10-01
 
−
endif
 
−
 
−
# Date string DDDHHMM
 
−
DATE = `date +%j%H%M`
 
−
 
−
#=============================================================================
 
−
# Makefile targets: type "make help" for a complete list!
 
−
#=============================================================================
 
−
 
−
.PHONY: all geos clean realclean fileclean doc docclean help logclean
 
−
 
−
all: geos
 
−
 
−
geos:
 
−
@$(MAKE) -C $(GEOSDIR)
 
−
cp -f $(GEOSDIR)/bin/geos .
 
−
@$(MAKE) logclean
 
−
  ./geos > log.$(DATE) &
 
−
tail -f log.$(DATE)
 
−
 
−
clean:
 
−
@$(MAKE) -C $(GEOSDIR) clean
 
−
@$(MAKE) logclean
 
−
 
−
realclean:
 
−
@$(MAKE) -C $(GEOSDIR) realclean
 
−
@$(MAKE) fileclean
 
−
rm -f geos
 
−
 
−
fileclean:
 
−
@$(MAKE) logclean
 
−
rm -f ctm.bpch*
 
−
rm -f Ox.mass.*
 
−
rm -f *2013080100*
 
−
rm -f *.run.*o*
 
−
 
−
doc:
 
−
@$(MAKE) -C $(GEOSDIR) doc
 
−
 
−
docclean:
 
−
@$(MAKE) -C $(GEOSDIR) docclean
 
−
 
−
help:
 
−
@$(MAKE) -C $(GEOSDIR) help
 
−
 
−
logclean:
 
−
rm -f *.log
 
−
 
−
At the heart of this Makefile are two important blocks of code, the first being:
 
−
 
−
# Make the development version "Code" the default directory
 
−
ifndef GEOSDIR
 
−
GEOSDIR = /home/bmy/Code.v10-01
 
−
endif
 
−
 
−
# Date string DDDHHMM
 
−
DATE = `date +%j%H%M`
 
−
 
−
This block defines the location of the GEOS–Chem source code directory, which is saved in a variable called <tt>GEOSDIR</tt>. If a value for <tt>GEOSDIR</tt> is not passed as a command-line argument, then <tt>GEOSDIR</tt> will be set to <tt>/home/bmy/Code.v10-01</tt> (you can edit this location for your own setup). Also, a default date/time string is saved in the variable <tt>DATE</tt>. This date/time string will be appended to the GEOS–Chem log file output.
 
−
 
−
The second block of code is used to compile and run the GEOS–Chem code:
 
−
 
−
geos:
 
−
@$(MAKE) -C $(GEOSDIR)
 
−
cp -f $(GEOSDIR)/bin/geos .
 
−
@$(MAKE) logclean
 
−
  ./geos > log.$(DATE) &
 
−
tail -f log.$(DATE)
 
−
 
−
The lines:
 
−
 
−
@$(MAKE) -C $(GEOSDIR)
 
−
cp -f $(GEOSDIR)/bin/geos .
 
−
 
−
tell GNU Make to call down to the router makefile in the GEOS–Chem source code directory <tt>/home/bmy/Code.v10-01</tt>. GNU Make will compile GEOS–Chem and create the executable file <tt>/home/bmy/Code.v10-01/bin/geos</tt>. This file is then copied to the run directory.
 
−
 
−
The next 3 lines:
 
−
 
−
@$(MAKE) logclean
 
−
./geos > log.$(DATE) &
 
−
tail -f log.$(DATE)
 
−
 
−
removes the log file if it already exists, runs the GEOS–Chem executable (thus starting the simulation), and follows the log file output with the Unix <tt>tail -f</tt> command.

== Technical Issues ==
 
−
 
−
=== GNU Make is required ===
 
−
 
−
The makefiles described above are designed to be used with [http://www.gnu.org/software/make/ GNU Make].  This is free, open-source software and is bundled with most of the popular Unix versions today (e.g. various Linux builds, Ubuntu, Fedora, etc.). 
 
−
 
−
It is recommended to use GNU Make because not all Unix make utilities are compatible with each other.  GNU Make is probably the most flexible make utility available. 
 
−
 
−
If GNU Make is not already installed on your system, then you (or your IT guru) will have to install it.  You can check to see if GNU Make is already installed by typing:
 
−
 
−
make --version
 
−
 
−
at the Unix prompt.  GNU Make will display a version screen similar to this:
 
−
 
−
GNU Make 3.81
 
−

−
 
−
=== Install LaTeX utilities for auto documentation ===
 
−
 
−
Many of the updated GEOS-Chem source code files now use the [[Automatic documentation with protex|ProTeX documentation headers]].  The <tt>protex</tt> script (included in the <tt>Code/doc</tt> subdirectory) strips the information from the documentation headers located in GEOS-Chem
 
−
 
−
* Modules
 
−
* Subroutines
 
−
* Functions
 
−
* Include files
 
−
 
−
and creates a LaTeX format <tt>(*.tex)</tt> file.  The <tt>latex</tt> utility can then be used to produce output in PDF (<tt>*.pdf</tt>) and PostScript (<tt>*.ps</tt>) formats from the LaTeX file.  This all happens automatically when you type:
 
−
 
−
make doc
 
−
 
−
at the Unix prompt.  However, you must make sure to have the LaTeX utilities installed on your machine in order to be able to generate this automatic documentation.  The LaTeX utilities include:
 
−
 
−
;latex  : Converts LaTeX format files to Device-Independent format (<tt>*.dvi</tt>)
 
−
;dvips  : Converts Device-Independent format to PostScript format
 
−
;dvipdf : Converts Device-Independent format to PDF format
 
−
 
−
The LaTeX utilities may be packaged with your version of Unix.  Ask your IT guru for more information.
 
−
 
−
You may also want to install the following packages:
 
−
 
−
;ghostview : Reader for PostScript files
 
−
;acroread  : Adobe Acrobat Reader for PDF files

=== Compile-time options that can slow down GEOS-Chem ===
 
−
 
−
The following compile-time options can cause a GEOS-Chem job to run more slowly than usual:
 
−
 
−
;DEBUG=yes: This is required for running GEOS-Chem in a debugger such as idb or Totalview.  This will invoke the <tt>-g -O0</tt> compiler options, which turn off all optimization.
 
−
;BOUNDS=yes: This option turns on runtime [[Common GEOS-Chem error messages#Array out-of-bounds error|array-out-of-bounds]] checking, which looks for instances of invalid array indices (i.e. If the <tt>A</tt> array only has 10 elements but you try to reference <tt>A(11)</tt>.)
 
−
;FPE=yes: This option turns on error checking for floating-point exceptions (i.e. div-by-zero, NaN, floating-invalid, and similar errors).
 
−
;OMP=no: This option turns off the OpenMP parallelization (which is turned on by default).
 
−
 
−
If you have selected any of the above options, then try compiling GEOS-Chem from scratch, i.e.,
 
−
 
−
make realclean
 
−
make -j4 MET=____ GRID=____
 
−
 
−
and then re-run your GEOS-Chem job.

Overview

GEOS-Chem and GCHP use two build systems to compile source code files into an executable file:

  1. GNU Make
  2. CMake

Starting in 13.0.0 both GEOS-Chem "Classic" and GCHP use CMake exclusively.

Which versions can use GNU Make and which can use CMake?

GEOS-Chem "Classic" compatibility matrix

Some GEOS-Chem "Classic" versions are compatible with both CMake and GNU Make, as shown below.

GEOS-Chem "Classic" version Uses GNU Make? Uses CMake?
12.5.0 and prior YES NO
12.6.* YES YES
12.7.* YES YES
12.8.* YES YES
12.9.* YES YES
13.0.0 and later NO YES

GCHP compatibility matrix

Unlike GEOS-Chem "Classic", GCHP had a "hard" transition from GNU Make to CMake in 13.0.0:

GCHP version Uses GNU Make? Uses CMake?
12.5.0 and prior YES NO
12.6.* YES NO
12.7.* YES NO
12.8.* YES NO
12.9.* YES NO
13.0.0 and later NO YES
