  • AmgX provides a simple path to accelerated core solver technology on NVIDIA GPUs. AmgX provides up to 10x acceleration to the computationally intense linear solver portion of simulations, and is especially well suited for implicit unstructured methods.

    It is a high performance, state-of-the-art library and includes a flexible solver composition system that allows a user to easily construct complex nested solvers and preconditioners.

    Get Started with AmgX Today

    The AmgX library offers optimized methods for massive parallelism, the flexibility to choose how the solvers are constructed, and is accessible through a simple C API that abstracts the parallelism and GPU implementation.

    Using the methods and tools from the AmgX library, developers can easily create specialized solvers using AmgX core methods and rapidly deploy solution on GPU workstations, servers and clusters.
