Overview

This is a library for solving the eikonal equation in Cartesian coordinates using the fast sweeping method. The implementation relies on SYCL thereby allowing the same code to be run on a CPU or GPU.

Installation

Prerequisites

The library requires

1. CMake 3.10 or higher.
2. A C++20 compliant compiler.
3. A SYCL v1.2 compliant compiler - e.g., dpcpp or Intel.
4. spdlog
5. Boost

Optionally, to build the Python bindings the following are needed

1. Python3
2. pybind11

Configuration

An example configuration script utilizing the Intel compiler is given

#!/usr/bin/bash
BUILD_DIR=intel_build
if [ -d ${BUILD_DIR} ]; then
   rm -rf ${BUILD_DIR}
fi
mkdir ${BUILD_DIR}
cd ${BUILD_DIR}
cmake .. \
-DCMAKE_CXX_COMPILER=/opt/intel/oneapi/compiler/2021.1.1/linux/bin/icpx \
-DCMAKE_CXX_FLAGS="-Wall -tbb -fsycl -fsycl-unnamed-lambda" \
-DWRAP_PYTHON=TRUE \
-DPYTHON_EXECUTABLE=/home/bbaker/anaconda3/bin/python \
-DPYTHON_INCLUDE_DIRS=/home/bbaker/anaconda3/include/python3.8 \
-DPYTHON_LIBRARIES=/home/bbaker/anaconda3/lib

After configuration descend into the build directory and type

make
make test
