The history of the Fortran language can be traced straight to IBM. Fortran was originally proposed by John Backus in 1953, and the initial Fortran compiler, for IBM mainframe computers, was delivered in 1957.
Fast-forward to today, and Fortran is widely used on the field of High-Performance Computing. It has become an ANSI standard, and has been implemented on all major platforms on this space. What makes Fortran successful on this space is its ability to provide developers with very good performance for numerical computation withour requiring extensive tuning. The Fortran language has been designed in a way that facilitates program optimization without the need for complicated program analysis.
IBM continues having a strong commitment to the Fortran language, given its widespread use on the HPC space. The current family of IBM Fortran implementations is the XLF compiler, available for AIX, Linux on Power, and the IBM Blue Gene supercomputer systems. The current version of this compiler, XLF 13.1, features full FORTRAN 2003 support, a complete OpenMP 3.0 implementation, and extensive exploitation of the IBM POWER7 microprocessor.
We are opening this forum to create more direct communication between users of the XLF compilers and the IBM compiler development organization. We hope you'll find the content informative and interesting, and look forward to your contribution as well through ques
