Workflow of SWIT

SWIT Installation

Step 1: Install gfortran

# Install gcc and gfortran
sudo apt-get install build-essential
sudo apt install gfortran

Step 2 : Install OpenMPI

# Download the latest OpenMPI package, or go to  http://www.open-mpi.org/software/ompi to download the desired version
wget https://download.open-mpi.org/release/open-mpi/v4.1/openmpi-4.1.1.tar.gz 
tar xvfz openmpi-4.1.1.tar.gz
cd openmpi-4.1.1

# Configure the installation files and install OpenMPI (this would take quite a while)
./configure --prefix=/usr/local/openmpi CC=gcc FC=gfortran
make    # make -j8  # use 8 cores to speed up the make process
sudo make install

# Add env path at your ~/.bashrc
vim ~/.bashrc
export PATH=/usr/local/openmpi/bin:$PATH
source ~/.bashrc

# Check OpenMPI is successfully installed
which mpirun

Step 3 : Install Anaconda Environment (Otherwise, just install Python dependencies as you like)

# Anaconda is recommended. For installing Anaconda, please refer to https://docs.anaconda.com/anaconda/install/linux/
# 1. download package from: https://www.anaconda.com/products/individual/download-success
# 2. bash your_downloaded_Anaconda_package

# Create the conda environment for SWIT if you use Anaconda
conda create --name SWIT python=3.7.5
conda activate SWIT

# Install dependencies using USTC mirrors (whether use Anaconda or not)
pip install numpy obspy scipy matplotlib multiprocess PySimpleGUI psutil Pillow -i https://pypi.mirrors.ustc.edu.cn/simple/

Step 4 : Install & Run SWIT

# Complie the fd2dmpi forward solver with the default fortran compiler (mpif90).
# If you want to use other fortran compiler, you can edit the Makefile.config file (line 18) under ~/SWIT-1.0/fd2dmpi/.
cd /your/own/path/to/SWIT-1.0/fd2dmpi/
rm *.mod
make clean
make

# Add fd2dmpi and Python toolbox to the env path at your ~/.bashrc 
vim ~/.bashrc 
export PATH=/your/own/path/to/SWIT-1.0/bin:$PATH
export PYTHONPATH=/your/own/path/to/SWIT-1.0/toolbox
source ~/.bashrc

# Option 1. Run SWIT via GUI
cd /your/own/path/to/SWIT-1.0/toolbox/
python runswit_Linux.py    # or python runswit_MacOS.py 

# Option 2. Run SWIT via the Python script
cd /your/own/path/to/SWIT-1.0/example/some_case/
./run_workflow     # You need to modify all the paths in the Python script before running

# Notice:
# If you use the Intel Compiler, you need to make the following change in forward and adjoint functions in toolbox/solver.py: 
# Before:     
#	   solver_cmd = 'mpirun -np %d  fd2dmpi par=%s' % (mpiproc, parfile)
# After:
#    solver_cmd = 'mpiexec -np %d  fd2dmpi par=%s' % (mpiproc, parfile)

Systems

SWIT-1.0 has been tested on Ubuntu 16.04, 18.04, 20.04, Centos 7.
It seems that SWIT-1.0 cannot run on MacOS properly due to the problem with the Python multiprocess module. 
This issue will be fixed in the near future.

    Hi Haipeng,

    I am installing this package on my macbook pro M1. I have openmpi installed:

    Questions about free surface

    Thank you for your work.

    PML =50, whether free surface is set to Yes or No and the result seems to be the same. I don't know why.

    In addition, on line 154 of base.py, "self.nz_pml = self.nz + self.pml * (2 - self.fs)". Can you explain what it means and where self.nz_pml is used

    I would appreciate it if you could take some time to answer my questions.

    The data filtering becomes very slow due to large OMP_NUM_THREADS for Scipy

    I add a default specification for OMP_NUM_THREADS in base.py (Line 70):

    os.environ["OMP_NUM_THREADS"] = "1" # export OMP_NUM_THREADS=1

    The data filtering speed is faster now.
