Get support for Arm Fortran Compiler

Linux user-space compiler, tailored for HPC and scientific codes and available as part of the commercially supported Arm Allinea Studio tool suite.

Arm Fortran Compiler has wide Fortran application coverage and generates optimal code on 64-bit Armv8-A based platforms. The compiler also supports Arm Scalable Vector Extension (SVE), an Arm architecture extension highly suited for HPC.

  • ARM C/C++ Compiler
  • Based on Flang and LLVM

    Our compiler is built on the PGI open source Flang front-end and the LLVM based optimization and code generation back-end, providing users with the best application coverage and optimal code on Arm. See our support status for Fortran 2003 and Fortran 2008 languages.
