Hardware and Operating-System Support

The XL Fortran Advanced Edition Version 9.1 compiler is supported on several Linux distributions. See the IBM XL Fortran Advanced Edition V9.1 for Linux Installation Guide and README file for a list of supported distributions and requirements.

The compiler, its generated object programs, and run-time library will run on all POWER3(TM), POWER4(TM), POWER5, PowerPC 970, and PowerPC(R) systems with the required software, disk space, and virtual storage.

The POWER3, POWER4, or POWER5 processor is a type of PowerPC. In this document, any statement or reference to the PowerPC also applies to the POWER3, POWER4, or POWER5 processor.

To take maximum advantage of different hardware configurations, the compiler provides a number of options for performance tuning based on the configuration of the machine used for executing an application. IBM Copyright 2003
