Devil Ray is now developed as part of Ascent (https://github.com/Alpine-DAV/ascent).
It was moved as part of a great amalgamation to simplify ongoing development and support of Ascent and Devil Ray.
Devil Ray is a visualization and analysis library for high-order elememt meshes targeting modern HPC architectures. Devil Ray runs on both GPUs and many-core CPUs. Further, Devil Ray leverages MPI for distributed-memory computations. We support meshes consisting of hexs, quads, tets, and triangles of arbitray polynomial order, with fast paths for constant, linear, quadratic, and cubic elements. Originally architected as a ray tracer, Devil Ray is capable of rendering volumes and surfaces. Additonally, we support a limited set of filters and spatial queries. Devil Ray has been demonstrated running concurrently on over 4,000 GPUs.
Devil Ray uses a Spack-based build system. We include several Spack configuration directories that include both OpenMP and CUDA configs. We require CMake 3.9 or greater when building with OpenMP and CMake 3.14 or greater when building with CUDA. Example of building on LLNL's Pascal cluster:
git clone --recursive https://github.com/LLNL/devil_ray.git
cd devil_ray
python ./scripts/uberenv/uberenv.py --spack-config-dir=./scripts/uberenv_configs/spack_configs/llnl/pascal_cuda/
mkdir build
cd build
ml cmake
ml cuda
cmake -C ../uberenv_libs/pascal1-toss_3_x86_64_ib-gcc@4.9.3-ascent.cmake ../src/
make
