Besides GitHub, GitLab, SourceForge, and Netlib, there are also domain-specific repositories with Fortran code, with a few listed at the Fortran Wiki below. Are there other such repositories specific to a scientific or engineering discipline?
- Geophysics source-code archive - codes that accompany articles published in the “Geophysical Software and Algorithms” section in the journal Geophysics.
- HEPForge - development environment for high energy physics software projects
- Biostatistics software from the University of Texas
- Crystallography Source Code Museum
- MGNet - repository for information related to multigrid, multilevel, multiscale, aggregation, defect correction, and domain decomposition methods.
- NonSmooth Optimization (NSO) Software codes by Napsu Karmitsa and coworkers and links to codes by others. Site also has codes for clustering, regression, and imputation.
- Radiation Safety Informational Computational Center (RSICC) - Since its inception in 1962, RSICC has evolved into one of the world’s leading resources for a broad range of the best available nuclear computational tools and services.
- Public Domain Aeronautical Software - valuable aeronautical computer programs complete with public domain source code, instructions and sample cases.
- Collected Algorithms (CALGO) from ACM - Software associated with papers published in the Transactions on Mathematical Software, as well as other ACM journals are incorporated in CALGO. This software is refereed for originality, accuracy, robustness, completeness, portability, and lasting value.
- StatLib—Applied Statistics algorithms
