Gfortran

GNU Fortran (gfortran) is open-source Fortran compiler from the GNU Compiler Collection (GCC). It supports multiple Fortran standards, including Fortran 77, Fortran 90, Fortran 95, Fortran 2003, Fortran 2008, and Fortran 2018, making it a versatile tool for scientific computing and numerical simulations. gfortran is widely used for developing high-performance applications in areas such as physics, engineering, and finance.

• Supports a wide range of Fortran standards, from Fortran 77 to Fortran 2018.
• Optimizes code for better performance on different hardware platforms.
• Provides full integration with the GNU toolchain, including debugging and profiling tools like GDB and gprof.
• Supports advanced features such as automatic parallelization, vectorization, and SIMD (Single Instruction, Multiple Data).
• Can be used in combination with other GCC languages, such as C and C++, for mixed-language programming.
