Xolotl is a continuum simulator under development within two DOE SciDAC programs, available at https://github.com/ORNL-Fusion/xolotl . It is a high-performance computing code using advection-reaction-diffusion (ADR) kinetic rate theory to model the time evolution of the divertor material in next generation tokamaks like ITER, as well as nuclear fuel in fission reactors.
- C++17 compiler
- CMake >= 3.13
- MPI
- Boost
- Kokkos >= 4.4
- HDF5
- PETSc >= 3.16 (configured with kokkos and kokkos-kernels; see scripts/build_petsc.sh)
Xolotl can now build all dependencies (using PETSc's build system) during the CMake configure step:
cd $HOME
git clone https://github.com/ORNL-Fusion/xolotl $HOME/xolotl-source
mkdir $HOME/xolotl-build
cd $HOME/xolotl-build
cmake \
-DXolotl_BUILD_PETSC=ON \
[-DXolotl_ENABLE_CUDA=ON | -DXolotl_ENABLE_OPENMP=ON] \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=$HOME/xolotl-build/install \
$HOME/xolotl-source/
make
make test
make install
If Boost, HDF5, or LAPACK are not found during configuration, they will
automatically be requested from PETSc's build system. Or you can specify this
directly via -DXolotl_BUILD_BOOST=ON, etc.
If you wish to configure and install PETSc separately, use (or reference) our PETSc build script.
You can find more information about this code on our Wiki and how to install Xolotl and its dependencies in Build Configuration.
Once installed, you can use a Benchmark file to run the code:
./xolotl <input_parameter_file>
as described in Running Xolotl, with the description of the different options at Parameter File and PETSc Options.
If you want to contribute please check Guidelines.
A list of publications using Xolotl is available at Publications.
For any question you can send an email to our mailing list: xolotl-psi-development@lists.sourceforge.net.
