Description

IBM XL Fortran Advanced Edition V9.1 for Linux is a tool for developing high performance application.

FORTRAN 77, Fortran 90, Fortran 95 standards and Fortran 2003 draft standard: XL Fortran Advanced Edition V9.1 for Linux is a compiler that complies with FORTRAN 77, Fortran 90 and Fortran 95 standards. It extends support for additional Fortran 2003 draft standard features. It also supports IBM and common industry extensions from various compiler vendors.

Newly supported Fortran 2003 features include:

The ISO_C_BINDING intrinsic module, BIND(C) attribute/statement, module variables, common block, subroutine/function and -qalign=bindc compiler suboption provide support for interoperability with C.
The PUBLIC/PRIVATE attribute for derived type components provides accessibility of each component.
The ASSOCIATE construct associates an entity with either a variable or the value of an expression.
Command-line argument intrinsics:
- COMMAND_ARGUMENT_COUNT
- GET_COMMAND_ARGUMENT
- GET_ENVIRONMENT_VARIABLE
The FLUSH statement makes data from an external file available to other process.
The ISO_FORTRAN_ENV intrinsic module provides public entities relating to the Fortran environment.
The IMPORT statement makes named entities from the host scoping unit accessible in the interface body by host association.
The PROCEDURE statement declares a dummy procedure or external procedure.
The IOMSG= specifies for I/O statements provides an explanatory message on error, end-of-record, or end-of-life conditions.
The NEW_LINE intrinsic returns the new line character.
The 2003std run-time options provide conformance checking of code for adherence to the Fortran 2003 draft standard.

OpenMP API: OpenMP is an industry specification describing a common set of APIs which support Symmetric Multi-Processing (SMP) programming in C/C++ and Fortran on all architectures, including UNIX^® and Windows NT™ platforms. OpenMP is a portable, scalable model, which gives shared-memory parallel programmers a simple and flexible interface for developing parallel applications for platforms ranging from the desktop to the supercomputer.

XL Fortran Advanced Edition V9.1 for Linux provides full support for the OpenMP Fortran API V2.0. For more information on the OpenMP Fortran API V2.0, visit

http://www.openmp.org/specs/

Exploiting the POWER5 architecture and BladCenter JS20: XL Fortran Advanced Edition for Linux provides support for IBM PowerPC Architecture™ and the POWER4, POWER5, and PowerPC 970 extensions to it. V9.1 adds new exploitation of POWER5 — the latest hardware architecture, and IBM BladeCenter JS20 with PowerPC 970 processor. The -qarch and -qtune compiler options instruct the compiler to generate and tune code to a specific architecture respectively. This allows the compiler to take advantage of machine-specific instructions to further improve performance. The -qarch option specifies the target architectures on which the resulting programs will run. The -qtune and -qcache options refine the degree of platform-specific optimization performed.

Industry-leading optimization technology: XL Fortran Advanced Edition V9.1 for Linux includes industry-leading optimization technology. Through compiler options and directives, programmers are offered a number of ways to optimize their code. A range of optimization levels (-O2, -O3, -O4 and -O5) allow you to perform from comprehensive low-level optimization to more extensive whole-program optimization. Other compiler options for optimization:

-qarch and -qtune instruct the compiler to generate code for a specific architecture.
-qhot allows for high-order transformations that specifically improve performance of loops.
-qipa invokes interprocedural analysis (IPA) and enables the compiler to optimize across different files (whole-program analysis); this can result in significant performance improvements.
-qpdf tunes optimizations through profile-directed feedback (PDF); results from sample program execution on "train" data sets are used to fine tune optimizations in conditional branches and frequently executed code sections.
-qshowpdf option, which is used together with -qpdf1 option, provides additional information to an executable so that PDF record can be displayed by the showpdf tool.
Optimization utilities showpdf and mergepdf are used to view and manipulate information gathered by PDF (-qpdf1/-qpdf2) to enhance PDF-directed compilation.

Symbolic debugger support: Use gdb or other symbolic debuggers for your programs.

Port or migration support: XL Fortran Advanced Edition V9.1 for Linux provides full Fortran language standards compliance. The xlf, f77, and fort77 commands enable maximum compatibility with existing FORTRAN 77 programs. The default options, provided with the xlf90 command, give access to the full range of Fortran 90 language features. Similarly, the default options provided with the xlf95 command give access to the full range of Fortran 95 language features.

In addition, XL Fortran Advanced Edition V9.1 for Linux provides a comprehensive set of language extensions (such as intrinsic functions, data types) enabling ease of porting from other platforms and many different kinds of compiler vendors as well. Several options, including -qport, are offered to minimize your porting effort.

Run-Time environment: XL Fortran Advanced Edition V9.1 for Linux provides a run-time environment to support library modules, and I/O services and utilities. The XL Fortran run-time environment includes both single-threaded and multi-threaded versions to maximize the performance available to both types of applications. Various aspects of the XL Fortran run-time, including I/O characteristics, error reporting, and obsolete language feature support, can be controlled using environment variables.

New or changed compiler options and other features

-qflttrap=nanq detects all NaN values handled or generated by floating point instructions, including those not created by invalid operations.
-qport=nullarg treats an empty argument, which is delimited by a left parenthesis and a comma, two commas, or a comma and a right parenthesis, as a null argument.
-qmodule=mangle81 provides compatibility with V8.1 module naming conventions for non-intrinsic modules.
-qsaveopt saves the command-line options used for compiling a source file in the corresponding object file.
-qversion provides the version and release for the invoking compiler.
Subset of Mathematical Acceleration SubSystem Vector (MASSV) libraries available.
VMX support with automatic SIMD vectorization on SLES 9 running on BladeCenter JS20.
32-bit and 64-bit modules are now included in a single module file.
