1 =============
2 sphere readme
3 =============
4 ``sphere`` is a 3D discrete element method algorithm utilizing CUDA. ``sphere``
5 allows for optional simulation of two-way coupled fluid flow using the
6 Navier-Stokes or Darcy formulations.
7
8 A powerful Nvidia GPU with proper support for double precision floating is
9 highly recommended. ``sphere`` has been tested with Nvidia Tesla GPUs, and has
10 successfully been employed on the clusters `Grendel
11 <https://www.cscaa.dk/grendel/hardware/>`_ (Aarhus University), `ICME
12 <https://icme.stanford.edu/computer-resources/gpu-cluster>`_ (Stanford
13 University), `Comet <https://www.sdsc.edu/services/hpc/hpc_systems.html#comet>`_
14 (San Diego Supercomputing Center), `Bridges
15 <https://psc.edu/index.php/resources/computing/bridges>`_ (Portland
16 Supercomputing Center), and `Stampede <https://www.tacc.utexas.edu/stampede/>`_
17 (Texas Advanced Supercomputing Center).
