Welcome to the GEOS project!

-----------------------------

GEOS is a simulation framework for modeling coupled flow, transport, and geomechanics

in the subsurface.  The code provides advanced solvers for a number of target applications,

including

  - carbon sequestration,

  - geothermal energy,

  - and similar systems.  



A key focus of the project is achieving scalable performance on current and next-generation

high performance computing systems.  We do this through a portable programming model and research into scalable algorithms.

Who develops GEOS?

-------------------

GEOS is an open source project and is developed by a community of researchers at

several institutions.  The bulk of the code has been written by contributors from

four main organizations:

  - Lawrence Livermore National Laboratory,

  - Stanford University,

  - TotalEnergies,

  - Chevron



See our

[authors](https://geosx-geosx.readthedocs-hosted.com/en/latest/docs/sphinx/Contributors.html)

page for more details.  



How does GEOS relate to the earlier GEOS code?

------------------------------

GEOS is the offshoot of an earlier code developed at LLNL also called GEOS.  The new

code differs from our previous efforts in two important ways:

  - This new code GEOS uses a fundamentally different programming model to achieve

    high performance on the complicated chip architectures common on today's

    HPC systems.  This code is ready for exascale-class systems as they are delivered.

  - The new code has been released as an open-source effort to encourage collaboration

    within the research and industrial community.  See the release notes below

    for details of the [LGPL 2.1 License](./LICENSE) that has been adopted.
