About ADAM

ADAM (Accelerated fluid Dynamics on Adaptive Mesh refinement grids) is a high-performance fluid dynamics framework written in modern Fortran for device(GPU)-accelerated HPC simulations and traditional CPU-based superpc. It provides physics-agnostic SDK library offering AMR, IB, WENO, RK, parellel I/O, ecc... on top of which is easy to develop CFD solvers. The maintained applications are PRISM, an electromagnetic and plasma solver, and FLUME, a compressible Euler and MHD solver.

The primary focus is on large-scale scientific computing: ADAM targets exascale deployments on device-accelerated clusters, where thousands of devices (GPU) nodes work in concert via MPI with node-level parallelism provided by OpenACC (NVIDIA GPUs) or OpenMP offloading (AMD GPUs).

Key capabilities

• AMR — Morton-order linearized octree/quadtree; refinement at initialization by geometric, gradient and total-variation markers, and runtime regridding in FLUME ([amr] frequency)
• Immersed Boundary — complex and moving geometries without body-fitted meshes
• High-order WENO — upwind reconstructions of order 1 to 9 and centred of order 2 to 8
• GPU backend — one FNL codebase compiles for OpenACC (nvfortran) and OpenMP offloading (amdflang)
• Elliptic solvers — FLAIL: FFT and AMR multigrid Poisson solvers, on CPU and GPU
• I/O — per-rank HDF5 files with an XDMF index, stream restart files, MPI-IO slices
