Fortran Compilers |
Compilers |
Fortran has several open source and commercial compilers.
GNU Fortran Compiler (gfortran) is a mature free and open source compiler, part of the GNU Compiler Collection.
OpenCoarrays is a library and compiler wrapper around gfortran which enables the parallel programming features of Fortran 2018 with gfortran.
Flang is a new front-end for Fortran 2018 that has been recently added to LLVM. It is implemented in modern C++ and uses a Fortran-oriented MLIR dialect for lowering to LLVM IR. This project is under active development.
Flang is an open source compiler based on the NVIDIA/PGI commercial compiler.
LFortran is a modern, interactive, LLVM-based Fortran compiler.
Intel Parallel Studio XE is Intel's suite of compilers, tools, and libraries for Fortran, C, C++, and Python. Intel offers the Linux edition of their compiler suite for free for open source contributors.
The latest NAG Fortran Compiler release (7.0) has extensive support for legacy and modern Fortran features including parallel programming with coarrays, as well as additional support for programming with OpenMP.
The Compiler also provides significant support for Fortran 2018 (atomic operations, events and tasks, plus other smaller features), almost all of Fortran 2008, complete coverage of Fortran 2003, and all of OpenMP 3.1. All platforms include supporting tools for software development: source file polishers, dependency generator for module and include files, call-graph generator, interface builder and a precision unifier.
PGI compilers deliver the performance you need on CPUs, with OpenACC and CUDA Fortran for HPC applications development on GPU-accelerated systems. OpenACC and CUDA programs can run several times faster on a single Tesla V100 GPU compared to all the cores of a dual-socket server, and interoperate with MPI and OpenMP to deliver the full power of today’s multi-GPU servers.
The Cray Compiling Environment (CCE) is the cornerstone innovation of Cray's adaptive computing paradigm. CCE builds on a well-developed and sophisticated Cray technology base that identifies regions of computation that are either sequential scalar, vector parallel or highly multithreaded. It includes optimizing compilers that automatically exploit the scalar, vector and multithreading hardware capabilities of the Cray system. CCE supports Fortran, C and C++.
IBM® XL Fortran for Linux is an industry standards-based programming tool used to develop large and complex applications in the Fortran programming language. It generates code that leverages the capabilities of the latest POWER9 architecture and maximizes your hardware utilization. IBM XL Fortran for Linux optimizes your infrastructure on IBM Power Systems™ in support of extensive numerical, scientific and high-performance computing.
The AMD Optimizing C/C++ Compiler (AOCC) compiler system is a high performance, production quality code generation tool. The AOCC environment provides various options to developers when building and optimizing C, C++, and Fortran applications targeting 32-bit and 64-bit Linux® platforms. The AOCC compiler system offers a high level of advanced optimizations, multi-threading and processor support that includes global optimization, vectorization, inter-procedural analyses, loop transformations, and code generation. AMD also provides highly optimized libraries, which extract the optimal performance from each x86 processor core when utilized. The AOCC Compiler Suite simplifies and accelerates development and tuning for x86 applications.
Linux user-space Fortran compiler. Tailored for HPC and scientific codes, with support for popular Fortran and OpenMP standards and tuned for leading server-class Arm-based platforms. Built on the open source Flang front-end, and the LLVM‑based optimization and code generation back-end. Available as part of the Arm Compiler for Linux package.
Our compilers build faster code more efficiently than ever before. Pro Fortran delivers Absoft’s exclusive AP load balancing (offering an increase in performance of up to 20%!), AVX, OpenMP 3.1, highly extended Fortran 95 compiler with F2003 and F2008 features,, FX3 graphical debugger, native tool suite integration, AMDAL HPC scientific and engineering library, and much more. Plus, Pro Fortran is the only compiler with Fast Data Visualization, an Absoft exclusive technology for graphical rendering and data output.
Oracle C, C++, Fortran Compiler is highly optimized for Oracle systems, on-premise and in the cloud
- Advanced code generation technology for the latest Oracle SPARC and x86 based systems
- Support for the latest industry standards, including C++14, C++11, C11 and OpenMP 4.0 and extensive GCC compatibility features
- Automatic code analysis during compilation and automatic stack overflow protection at application runtime
Combining the 32/64-bit LGF Rainier compiler with the classic Lahey/Fujitsu LF95 compiler, LF Professional v7.8 delivers! LGF Rainier has full Fortran 95/90/77 compliance with extensive support for the Fortran 2003 and 2008 standards. Lahey/Fujitsu LF95 offers best in class diagnostics. Includes the automatic-parallelizing GFortran compiler, Lahey/Fujitsu Fortran 95 compiler, Visual Studio 2015 Shell (compatible with VS2017), Lahey's Exclusive Visual Studio Fortran support, Winteracter WiSK Graphics package, and more!
Silverfrost FTN95 is a full Fortran 95 standards compliant compiler, capable of producing fast executables for Win32 and for Microsoft .NET. FTN95 ships with the world's best runtime checking and a great range of supporting software. All standard and many vendor-specific legacy language features are supported, so that Fortran projects may be any combination of Fortran 77, Fortran 90 and Fortran 95.
The Fortran compiler conforms to the Fortran-2003 standard (ISO/IEC 1539-1:2004) and supports many features from Fortran-2008 (ISO/IEC 1539-1:2010).
The following is a list of Fortran compilers that seem discontinued, so we do not list them above:
- Hewlett Packard
- Watcom
- PathScale
- G95
- Open64
- Unisys
Please let us know if there is any compiler that is not listed, or if we listed a compiler in the Discontinued section and it is in fact actively maintained.
