SELF is an object-oriented Fortran library that support the implementation of Spectral Element Methods for solving partial differential equations.
The SELF API is designed based on the assumption that SEM developers and researchers need to be able to implement derivatives in 1-D and divergence, gradient, and curl in 2-D and 3-D on scalar, vector, and tensor functions using spectral collocation, continuous galerkin, and discontinuous galerkin spectral element methods. Additionally, as we enter the exascale era, we are currently faced with a zoo of compute hardware that is available. Because of this, SELF routines provide support for GPU acceleration through AMD's HIP and support for multi-core, multi-node, and multi-GPU platforms with MPI.
All you need is a Fortran compiler that is compliant with the Fortran 2008 standard and supports C interoperability. You can see which compilers are regularly tested on the Github actions page. Additionally, the table below lists the supported compilers

"Supported" for us means that we test self regularly on the platforms listed; self may work just fine on a different platform. Of course, we want to have self working on as many platforms as possible; open an issue if you encounter any problems installing or running self on your own platform.
