Legacy IBM XL Fortran compilers are still available for use

What can IBM Open XL Fortran for AIX do for your business?

IBM Open XL Fortran for AIX® is IBM’s next-generation Fortran compiler, facilitating the creation and maintenance of applications that are written in Fortran for IBM Power. It optimizes your infrastructure on IBM Power platforms, supporting extensive numerical, scientific, and high-performance computing. With full exploitation of the latest Power10 architecture, IBM Open XL Fortran for AIX can generate code that leverages the capabilities of Power10 to maximize your hardware utilization.

IBM Open XL Fortran for AIX combines IBM XL Fortran technology with LLVM compiler infrastructure. LLVM is an open-source compilation framework that is actively maintained by a large development community, supporting multiple architectures and programming languages.


Maximize your Power hardware ROI

Capitalize on Power10 architecture, such as Matrix Multiply Accelerator (MMA), and maximize your return on investment with full hardware exploitation.

Optimize application performance

Take advantage of both common LLVM optimizations and IBM’s industry-leading technologies to improve workload performance.

Migrate applications to Power easily

Adheres with international programming language standards, including Fortran 2003, a subset of Fortran 2008, and language interoperability standards.

Enable continuous delivery

Faster build speed helps to shorten the development cycle, enable faster iterations, and provide continuous delivery for business-critical applications on AIX.

Accelerate the shift to the hybrid cloud model

Offer new monthly licenses per the virtual process core (VPC) charge unit. Enable you to license IBM Open XL compilers on virtual servers per the needed capacities when you transition to hybrid cloud.
