UnrealEngine

Then open some "x64 Native Tools Command Prompt" of Visual Studio and execute the following line which properly configures the environment to use the DPC++ compiler:

set "DPCPP_DIR=path_to_dpcpp_compiler"
set "PATH=%DPCPP_DIR%\bin;%PATH%"
set "PATH=%DPCPP_DIR%\lib;%PATH%"
set "CPATH=%DPCPP_DIR%\include;%CPATH%"
set "INCLUDE=%DPCPP_DIR%\include;%INCLUDE%"
set "LIB=%DPCPP_DIR%\lib;%LIB%"

Now download and unpack some recent TBB version for Windows, e.g. oneTBB 2021.2.0:

https://github.com/oneapi-src/oneTBB/releases/download/v2021.2.0/oneapi-tbb-2021.2.0-win.zip

To compile tutorials contained in this folder first create and enter a build folder inside the tutorial you want to compile. E.g. for the minimal tutorial execute:

cd minimal
mkdir build
cd build

Then configure the tutorial you would like to compile by pointing to the Embree and TBB installation on your system.

cmake -G Ninja
      -D CMAKE_CXX_COMPILER=clang++
      -D CMAKE_C_COMPILER=clang
      -D CMAKE_BUILD_TYPE=Release
      -D embree_DIR=%cd%\..\..\..\lib\cmake\embree-4.3.3\
      -D TBB_DIR=path_to_tbb\oneapi-tbb-2021.2.0\lib\cmake\tbb ..

Now you can build the tutorial:

cmake --build .

In order to run the tutorial you have to set the PATH to the bin folder in order to find the Embree DLL:

set PATH=%cd%......\bin;%PATH%

Now you can run the tutorial:

.\minimal.exe
.\minimal_sycl.exe

Compilation under Linux using SYCL

Install one of the SYCL compilers supported by Embree, see section [Compiling Embree / Linux SYCL Compilation] of the Embree documentation.

To properly configure your environment, you have to source the startup.sh of the unpacked DPC++ compiler:

source dpcpp_compiler/startup.sh

Now download and unpack some recent TBB version for Linux, e.g. oneTBB 2021.2.0:

wget https://github.com/oneapi-src/oneTBB/releases/download/v2021.2.0/oneapi-tbb-2021.2.0-lin.tgz tar xzf oneapi-tbb-2021.2.0-lin.tgz

To compile tutorials contained in this folder first create and enter a build folder inside the tutorial you want to compile. E.g. for the minimal tutorial execute:

cd minimal
mkdir build
cd build

Then configure the tutorial you would like to compile by pointing to the Embree and TBB installation on your system.

cmake -D CMAKE_BUILD_TYPE=Release \
      -D CMAKE_CXX_COMPILER=clang++ \
      -D CMAKE_C_COMPILER=clang \
      -D embree_DIR=`pwd`/../../../lib/cmake/embree-4.3.3/ \
      -D TBB_DIR=path_to_tbb/oneapi-tbb-2021.2.0/lib/cmake/tbb/ ..

Now you can build the tutorial:

cmake --build .

Now you can run the tutorial:

./minimal
./minimal_sycl
