What is Arm Fortran Compiler

Tuned for scientific computing by Arm for a wide-range for 64-bit Arm platforms

We work with many Arm hardware vendors to ensure that Arm Fortran compiler generates optimal code utilizing the salient features of the hardware, allowing you to get best performance out-of-the-box.

Support for latest Fortran standards

Arm Fortran Compiler provides full support for Fortran 2003 and prior standards. It also has partial support for Fortran 2008 with a plan to add more support in the future.

Built on top of LLVM and Flang

Our commercial compiler is based on two community-driven projects – LLVM for overall compiler infrastructure and Flang for Fortran frontend. This allows our users to benefit from advances from these projects in addition to specific tuning by Arm for our architecture.

Arm Fortran Compiler supports:

  • Fortran 2003 and prior standards
  • Partial support for Fortran 2008
  • OpenMP 3.1
  • 64-bit Arm platforms including Cavium ThunderX2 and Qualcomm Centriq.
  • Full support for SVE, an Arm architecture extension suited for HPC
  • Leading Linux distributions including Red Hat 7.3+, SLES 12+ and Ubuntu 16.04+
