Euler_kokkos

What is it ?

Provide performance portable Kokkos implementation for compressible hydrodynamics.

Dependencies

• Kokkos
• CMake with version >= 3.1

How to get Kokkos sources

Kokkos sources are included as a git submodule.

To download kokkos sources with project "euler_kokkos_two_phase" clone it with option "--recursive"

git clone --recursive https://github.com/ziqiangzou/euler_kokkos_two_phase.git

If you performed a regular "git clone", just type

git submodule init
git submodule update

to retrieve kokkos sources.

Build

A few example builds

Build without MPI / With Kokkos-openmp

Create a build directory, configure and make

mkdir build && cd build
cmake -DUSE_MPI=OFF -DKOKKOS_ENABLE_OPENMP=ON ..
make -j 4

Add variable CXX on the cmake command line to change the compiler (clang++, icpc, pgcc, ....)

./euler_kokkos ./test.ini --kokkos-threads=4

Developping with vim and youcomplete plugin

Assuming you are using vim (or neovim) text editor and have installed the youcomplete plugin, you can have semantic autocompletion in a C++ project.

Make sure to have CMake variable CMAKE_EXPORT_COMPILE_COMMANDS set to ON, and symlink the generated file to the top level source directory.
