Fortrana

Fortrana is a high-level, statically typed programming language designed for numerical and scientific computing. It aims to combine the performance of legacy Fortran with modern language features, supporting expressive array operations, multidimensional arrays, and efficient interoperability with C and Fortran code.

The language was developed by the Fortrana Consortium, established in 2015 to advance tools for numerical research. The name reflects its heritage from Fortran and its focus on reliable, high-performance computation.

Key features include a strong type system, first-class arrays and slices, explicit parallelism constructs for multicore and GPU execution, and a compiler that performs aggressive optimizations and automatic vectorization. Fortrana provides modules and a standard library with numerical types, random number facilities, and input/output support, along with a robust foreign-function interface.

Fortrana emphasizes portability and reproducibility. It supports cross-platform development on Linux, Windows, and macOS, with deterministic numerical kernels and a focus on reproducible results in scientific workflows.

Use cases include climate modeling, computational fluid dynamics, physics simulations, and engineering analyses. The language is commonly adopted in academic and research settings where integration with existing Fortran and C code is important.

As of the mid-2020s, Fortrana has reached 1.x releases with several compilers and backends. The ecosystem centers on the Foundation's official tools and community-driven projects, with ongoing work on documentation, tutorials, and benchmarking suites.
