High-performance parallel programming language

Features

High performance

Fortran has been designed from the ground-up for computationally intensive applications in science and engineering. Mature and battle-tested compilers and libraries allow you to write code that runs close to the metal, fast.

Statically and strongly typed

Fortran is statically and strongly typed, which allows the compiler to catch many programming errors early on for you. This also allows the compiler to generate efficient binary code.

Easy to learn and use

Fortran is a relatively small language that is surprisingly easy to learn and use. Expressing most mathematical and arithmetic operations over large arrays is as simple as you'd write them as equations on a whiteboard.

Versatile

Fortran allows you to write code in a style that best fits your problem: Imperative, procedural, array-oriented, object-oriented, or functional.

Natively parallel

Fortran is a natively parallel programming language with intuitive array-like syntax to communicate data between CPUs. You can run almost the same code on a single CPU, on a shared-memory multicore system, or on a distributed-memory HPC or cloud-based system. Coarrays, teams, events, and collective subroutines allow you to express different parallel programming patterns that best fit your problem at hand.
