gfortran compiles and runs the following testsuites and applications:

MPICH2 - Message Passing Interface library

OpenMPI - Message Passing Interface library

BOM - Bergen Ocean Model

MICRESS - Phase-field code

MOSES - Marine Simulation

GLIMMER - a 3D finite-difference ice sheet model

CAMx - The Comprehensive Air quality Model

BRAWLER - USAF Air-to-Air Combat Simulation Program

FRUIT - FORTRAN Unit Test Framework (note the changes to make the source standard compliant: s/function get_last_message_/function get_last_message_ ()/ and s/function is_last_passed_/function is_last_passed_ ()/ )

## Testsuites

NIST F77 - Testsuite

Polyhedron - Testsuite

ISO Varying String Testsuite - Lawrie Schonberger's Testsuite

## Math Libraries

BLAS - Basic Linear Algebra Subprograms for vector and matrix operations

LAPACK - Linear Algebra PACKage

ACML - AMD Core Math Library

MATRAN - A matrix wrapper for F95

MINPACK - Solving nonlinear equations and nonlinear least squares problems

SHTOOLS - Tools for working with spherical harmonics

MUESLI - a free numerical and graphical library, written mainly in Fortran 95. Very close to MATFOR which allows a MATLAB-like syntax in the Fortran code

PSBLAS - Parallel Sparse Basic Linear Algebra Subroutines

## Electronic Structure Codes

CPMD - Quantum chemistry, ab initio molecular dynamics

CP2k - atomistic and molecular simulations of solid state, liquid, molecular and biological systems

GAMESS(US) - The General Atomic and Molecular Electronic Structure System (GAMESS) is a general ab initio quantum chemistry package.

GAMESS(UK) - The General Atomic and Molecular Electronic Structure System (GAMESS) is a general ab initio quantum chemistry package. Note that the US and UK versions are really completely different programs, having split from a common ancestor a long time ago.

Gaussian 03 and 09 - electronic structure program, notoriously difficult to compile with many compilers, information on how to compile it with gfortran can be found here (in French; Google Translate)

VASP - Plane wave ab initio density functional theory

octopus - Density-functional theory program (time-dependent)

EXCITING - FP-LAPW density-functional code

Wien2k - FP-LAPW density-functional code (Release notes: "gfortran seems to be a very good compiler")

Abinit - an ab-initio density-functional-theory package

Tonto-1.0 & 2.3 - Quantum Chemistry program

FLEUR - FLAPW density-functional program

Augmented Spherical Wave package - Very fast ab initio density functional theory

Espresso (PWscf) - Plane-Wave Self-Consistent Field DFT code (startup.f90 change

`-malign-double`option,`util/pack.f`needs`-fno-range-check`option)CASINO - the Cambridge quantum Monte Carlo code

CASTEP - UK Plane-wave DFT electronic structure code - notorious as a "compiler-breaker"

BerkeleyGW - Plane-wave GW and Bethe-Salpeter equation code for quasiparticle and optical properties
