SEMIC-cpp

This repository wraps up SEMIC (Surface Energy and Mass balance model of Intermediate Complexity; Krapp et al., 2017) in C++.

The original SEMIC written in Fortran is available at following site: https://github.com/mkrapp/semic.

Install

Required Packages in python

• pybind11 - for compiling SEMIC written in cpp.
• numpy
• matplotlib

Install

• To install the pySEMIC.cpp for running SEMIC written in cpp (SEMIC-cpp), use following command.
• This work is only tested in linux machine, not window machine.

cwd = $(pwd)
mkdir build
cd build
cmake ../ -L -DCMAKE_INSTALL_PREFIX=${cwd}/../install
make 
make install

Window system

• Require Miscrotsoft Visual C++ 14.0 or greater.
• Download https://visualstudio.microsoft.com/visual-cpp-build-tools/
• Install developement verison of current project as follows:
• Window 10 > Visual Studio 2019
• Window 11 > Visual Studio 2019 or 2022

pip install -e .

Usage

import pyseb

% initialize variable
nx = 100 # number of grid
ntime = 365 # number of timestep in day

semic = pyseb.SEMIC()
semic.Initialize(nx)

Check runtime with using OpenMP

Figure. Runtime of SEMIC depending on number of threads using OpenMP. To operate testing runtime, SIMBA machine is used.
