ROMS-X is a new GPU-enabled code designed to replicate the functionality of the ROMS code but with the ability to exploit GPU architectures.

ROMS-X is built upon the AMReX software framework for massively parallel block-structured applications. The AMReX software framework provides performance portability across multiple architectures.

See Getting Started for instructions as to how to clone the ROMS-X and AMReX codes, and for how to build and run a ROMS-X example. Mimimum requirements for system software are also given there.

Documentation of the ROMS-X theory and implementation is available here .

In addition, there is doxygen documentation of the ROMS-X Code available here

See CONTRIBUTING.md for how to contribute to ROMS-X development.
