A non-linear least squares solver that is primarily developed by the Numerical Analysis group at STFC Rutherford Appleton Laboratory hsl@stfc.ac.uk.
AMD supports and contributes to the RALFit solver as part of its commitment to advancing open-source high-performance computing. Through this collaboration it helps ensure the solver benefits from the performance and scalability of AMD technologies.
The package is written in modern Fortran, and it provides a number of interfaces for other languages.
RALFit has been tested on Linux, although it should work on other platforms. It requires
- a modern Fortran compiler
- a C compiler
- a BLAS and LAPACK distribution
To compile, follow the instructions in libRALFit/README.md.
