Hi

The Devito DSL (https://www.devitoproject.org/) is a Python package to implement optimized stencil computation (e.g., finite differences, image processing, machine learning) from high-level symbolic problem definitions. Devito builds on SymPy and employs automated code generation and just-in-time compilation to execute optimized computational kernels on several computer platforms, including CPUs, GPUs, and clusters.

Key Features
  • A functional language to express finite difference operators.
  • Straightforward mechanisms to adjust the discretization.
  • Constructs to express sparse operators (e.g., interpolation), classic linear operators (e.g., convolutions), and tensor contractions.
  • Seamless support for boundary conditions and adjoint operators.
  • A flexible API to define custom stencils, sub-domains, sub-sampling, and staggered grids.
  • Generation of highly optimized parallel code (SIMD vectorization, CPU and GPU parallelism via OpenMP and OpenACC, multi-node parallelism via MPI, blocking, aggressive symbolic transformations for FLOP reduction, etc.).
  • Distributed NumPy arrays over multi-node (MPI) domain decompositions.
  • Inspection and customization of the generated code.
  • Autotuning framework to ease performance tuning.
  • Smooth integration with popular Python packages such as NumPy, SymPy, Dask, and SciPy, as well as machine learning frameworks such as TensorFlow and PyTorch.
Best regards
Gerard

If you mean the list of the website, I think listing devito there is fine. Feel free to make a PR.
