Cocoa: Coastal and Ocean Circulation on Accelerators
Overview
Cocoa is a modern C++20 re-implementation of the ADCIRC two-dimensional depth-integrated shallow water model, designed from the ground up for GPU acceleration using the Trilinos and Kokkos frameworks.
Key Features
- Multi-backend acceleration - CUDA (NVIDIA), HIP (AMD), OpenMP, or serial execution via Kokkos
- Distributed computing - MPI-based domain decomposition with ParMETIS partitioning
- Mixed precision - Double-precision compute with selective float storage of bandwidth-sensitive fields
- Unstructured meshes - Triangular finite element meshes in NetCDF format
- Complete physics - Bottom friction, lateral stress, tidal potential forcing, meteorological forcing
- Wet/dry algorithm - Robust wetting and drying for coastal inundation modeling
Running
cocoa -i config.yaml
For distributed runs:
mpiexec -np 4 cocoa -i config.yaml
Containers
Pre-built Docker containers are available on DockerHub under cocoaorg/cocoa, split into three families by accelerator toolchain (the tag suffix selects the family):
| Image | Hardware | Notes |
|---|---|---|
cocoaorg/cocoa:<tag>-cpu | CPU only (x86-64 and ARM64) | Single multi-arch tag; the ARM64 variant runs natively on Apple Silicon via Docker Desktop |
cocoaorg/cocoa:<tag>-cuda | NVIDIA GPUs (CUDA) | GPU-only; volta70-blackwell100 |
cocoaorg/cocoa:<tag>-rocm | AMD GPUs (ROCm/HIP) | GPU-only; mi300, mi200 |
