This is the fastest way to get running.
Step 1: Install Docker Community Edition.
Step 2: (Optional) Run the PartMC test suite with:
docker run -it --rm compdyn/partmc bash -c 'cd /build; make test'
Step 3: Run a scenario like the following. This example uses partmc/scenarios/4_chamber
. This mounts the current directory ($PWD
, replace with %cd%
on Windows) into /run
inside the container, changes into that directory, and then runs PartMC.
cd partmc/scenarios/4_chamber
docker run -it --rm -v $PWD:/run compdyn/partmc bash -c 'cd /run; /build/partmc chamber.spec'
In the above docker run
command the arguments are:
-it
: activates "interactive" mode so Ctrl-C works to kill the command--rm
: remove temporary docker container files after running-v LOCAL:REMOTE
: mount the LOCAL
directory to the REMOTE
directory inside the containercompdyn/partmc
: the docker image to runbash -c 'COMMAND'
: run COMMAND
inside the docker containerThe directory structure inside the docker container is:
/partmc # a copy of the partmc git source code repository
/build # the diretory in which partmc was compiled
/build/partmc # the compiled partmc executable
/run # the default diretory to run in
Required dependencies:
Optional dependencies:
Install cmake and NetCDF (see above). The NetCDF libraries are
required to compile PartMC. The netcdf.mod
Fortran 90 module file
is required, and it must be produced by the same compiler being
used to compile PartMC.
Unpack PartMC:
tar xzvf partmc-2.6.1.tar.gz
Change into the main PartMC directory (where this README file is located):
cd partmc-2.6.1
Make a directory called build
and change into it:
mkdir build
cd build
If desired, set environment variables to indicate the install
locations of supporting libraries. If running echo $SHELL
indicates that you are running bash
, then you can do something
like:
export NETCDF_HOME=/
export MOSAIC_HOME=${HOME}/mosaic-2012-01-25
export SUNDIALS_HOME=${HOME}/opt
export GSL_HOME=${HOME}/opt
Of course the exact directories will depend on where the libraries are installed. You only need to set variables for libraries installed in non-default locations, and only for those libraries you want to use. Everything except NetCDF is optional.
If echo $SHELL
instead is tcsh
or similar, then the environment
variables can be set like setenv NETCDF_HOME /
and similarly.
Run cmake with the main PartMC directory as an argument (note the double-c):
ccmake ..
Inside ccmake press c
to configure, edit the values as needed,
press c
again, then g
to generate. Optional libraries can be
activated by setting the ENABLE
variable to ON
. For a parallel
build, toggle advanced mode with t
and set the
CMAKE_Fortran_COMPILER
to mpif90
, then reconfigure.
Optionally, enable compiler warnings by pressing t
inside ccmake
to enable advanced options and then setting CMAKE_Fortran_FLAGS
to:
-O2 -g -fimplicit-none -W -Wall -Wconversion -Wunderflow -Wimplicit-interface -Wno-compare-reals -Wno-unused -Wno-unused-parameter -Wno-unused-dummy-argument -fbounds-check
Compile PartMC and test it as follows.
make
make test
To run just a single test do something like:
ctest -R bidisperse # argument is a regexp for test names
To see what make is doing run it like:
VERBOSE=1 make
To run tests with visible output or to make some plots from the
tests run them as follows. Note that tests often rely on earlier
tests in the same directory, so always run test_1
, then
test_2
, etc. Tests occasionally fail due to random sampling, so
re-run the entire sequence after failures. For example:
cd test_run/emission
./test_emission_1.sh
./test_emission_2.sh
./test_emission_3.sh # similarly for other tests
gnuplot -persist plot_species.gnuplot # etc...
To run full scenarios, do, for example:
cd ../scenarios/1_urban_plume
./1_run.sh
The main partmc
command reads .spec
files and does the run
specified therein. Either particle-resolved runs, sectional-code runs,
or exact solutions can be generated. A run produces one NetCDF file
per output timestep, containing per-particle data (from
particle-resolved runs) or binned data (from sectional or exact
runs). The extract_*
programs can read these per-timestep NetCDF
files and output ASCII data (the extract_sectional_*
programs are
used for sectional and exact model output).
