Fortran 77 and 90 codes by Mladen Rogina, covering ODEs, PDEs, linear algrebra, and other topics.

Fortran tools to write standardized NetCDF output for a variety of ocean circulation models. The files contain required metadata to be compatible with DMACS standards. A C++ particle trajectory tool reads NetCDF files to make particle paths.

Parallel plane wave pseudopotential program for atomistic total energy calculation based on density functional theory. It is designed for large system simulations to be run on large parallel computers like Cray T3E and IBM SP machines at NERSC. It is ...

Materials science total energy planewave pseudopotential Fortran 90 code, by Andrew Canning.

Fast global ionospheric and plasmaspheric model based on a combination of the parameterized output of several regional theoretical ionosphere models and an empirical plasmaspheric model.

LPOTT: Pion-Nucleus Scattering; PiN: Chiral Color Dielectric Quark Model for pi-Nucleon Interactions; and LPOTp: Polarized Proton Scattering from Polarized Nuclei, in Parallel, by Rubin Landau

Code for CTEQ, GRV, MRS, and ALEKHIN distributions.

High-order finite-difference Fortran 90 code for compressible hydrodynamic flows with magnetic fields. It is highly modular and can easily be adapted to different types of problems. The code runs efficiently under MPI on massively parallel shared- or ...

Several are implemented in Fortran.
