funwave-tvd-docker

Dockerfile for funwave-tvd model

using docker examples from :\

Build using:

docker build -t funwave-tvd:latest . (if using latest code)
docker build -t funwave-tvd:3.6 . (if using latest given release)

Run example (option 1)
docker run -it funwave-tvd:3.6
cd /FUNWAVE-TVD-Version_3.6/simple_cases/rip_2d/work\
compile for the model for that example
make
mpirun -np 4 --allow-run-as-root ./funwave--gnu-parallel-single input.txt

Run example (option 2)
Here mount your local FUNWAVE repo inside docker to be able to change details of the examples (e.g. nb of cores)
docker run -it -v /home/simon/Documents/GitHub/FUNWAVE-TVD/:/model_local/ funwave-tvd:3.6
cd ../model_local/FUNWAVE-TVD-Version_3.5/simple_cases/rip_2d/work
compile for the model for that example
make
mpirun -np 2 --allow-run-as-root ./funwave--gnu-parallel-single input.txt \

See more instructions for compiling and running here :
https://fengyanshi.github.io/build/html/setup.html
and more specifically here :
https://fengyanshi.github.io/build/html/make_and_cml_input.html \

The main starting point is to use a Makefile (copied from GNUMake or use one from example)
then edit it for your own application (parralel/single core), add flags etc..

#-----------BEGIN MAKEFILE---------------------------
FUNWAVE_DIR = ../../..
FUNWAVE_DIR = /model/FUNWAVE-TVD-Version_3.5/ # may need to edit this 
WORK_DIR    = .
COMPILER    = gnu  # or ifort // use gnu or ifort compile
PARALLEL    = true # true if model is to be run on multi cores / false is single core ** w
EXEC        = funwave 
PRECISION   = single # or double
#-----------DEFINE FLAGS-----------------------------
#         uncomment to choose the model
# FLAG_1  = -DCOUPLING
# FLAG_2  = -DZALPHA
# FLAG_3  = -DMANNING
# FLAG_4  = -DVESSEL
# FLAG_5  = -DMETEO
# FLAG_6  = -DWIND
# FLAG_7  = -DSEDIMENT
# FLAG_8  = -DCHECK_MASS_CONSERVATION
# FLAG_9  = -DTMP
# FLAG_10 = -DTRACKING
...

Running make will create an executable whose name depends on compilation options (parallel or sequential):
Make sure to run make clean if you modify and re-run the make\

To run with MPI : mpirun -np 4 --allow-run-as-root ./funwave--gnu-parallel-single input.txt
To run on single core : ./funwave--gnu-sequential-single input.txt\

**Notes

may need to add export OMPI_MCA_btl_vader_single_copy_mechanism=none to get rid of error message : "Read -1, expected 256000, errno = 1"
add --allow-run-as-root when running mpirun -np 9 --allow-run-as-root ./funwave--gnu-parallel-single input.txt
may need to set permission of outputs files to chmod 777 *
