Arm Fortran Compiler

Arm Fortran Compiler is a commercial compiler that is tailored for server, HPC, and scientific codes, with support for Fortran and OpenMP. The compiler is built on the open source Flang front-end, and the LLVM‑based optimization and code generation back-end.

Arm Fortran Compiler:

  • Is tuned for leading server-class Arm-based platforms, including Marvell ThunderX2, Fujitsu A64FX, and Arm Neoverse-N1 (including Amazon Graviton and Ampere Altra).
  • Supports the modern Fortran (2008 and prior) and OpenMP (4.5 and prior) standards.
  • Can generate Scalable Vector Extension (SVE) and Scalable Vector Extension two (SVE2) code.
  • Is supported on all leading Linux distributions: RHEL, SLES, and Ubuntu.
