Original Press Release:



IBM XL Fortran Advanced Edition V9.1 for Linux - Now Exploits IBM POWER5 Architecture



Overview
IBM XL Fortran Advanced Edition V9.1 for Linux(TM) is the follow-on product to IBM XL Fortran V8.1 for Linux. It supports the
following Linux distributions: SUSE LINUX Enterprise Server 9 for POWER(TM) (SLES 9) and Red Hat Enterprise Linux AS for POWER V3
(RHEL 3).

XL Fortran Advanced Edition V9.1 for Linux is a tool for developing high performance applications. With its extensive industry-leading optimization technology, you have a powerful development environment to build Fortran applications.

XL Fortran Advanced Edition for Linux is a highly optimizing, native Fortran compiler designed to exploit the IBM eserver pSeries® line of symmetric-multiprocessing (SMP) hardware. It supports IBM PowerPC® architecture and the POWER4(TM), POWER5(TM) and PowerPC 970 extensions to it. V9.1 adds new exploitation of POWER5 - the latest hardware architecture, and IBM eserver BladeCenter(TM) JS20 with PowerPC 970 processor.

XL Fortran Advanced Edition V9.1 for Linux is a standard-based compiler. XL Fortran fully supports OpenMP Fortran API V2.0 and is fully compliant with FORTRAN 77, Fortran 90, and Fortran 95 standards. It also provides partial support for the Fortran 2003 draft standard. XL Fortran supports both IBM and industry extensions as well.

With the V9.1 release, XL Fortran ships a subset of the IBM Mathematical Acceleration SubSystem Vector (MASSV) libraries of tuned mathematical intrinsic functions. In addition, Vector Multimedia Extension (VMX) with automatic SIMD vectorization is available with XL Fortran V9.1 for SLES 9 running on IBM eserver BladeCenter JS20 hardware.

Key prerequisites
o Linux distributions running on iSeries(TM) or pSeries:
