Compilations are hosted on a System p server, a PowerPC® processor-based blade server or a POWER™ processor-based blade server that generates optimized code for the Cell Broadband Engine™ (Cell/B.E.) processor within the BladeCenter® QS21. The XL Fortran for Multicore Acceleration for Linux on System p product gives application developers the tools to exploit the unique performance capability of processors compliant with the new Cell/B.E. Architecture.

The Cell/B.E. Architecture is an innovative and powerful microprocessor architecture that extends the 64-bit Power Architecture™ technology. It has the potential to accelerate applications in numerically intensive, graphical, and streaming applications, among others, in a variety of industries. The Cell/B.E. Architecture resulted from a collaboration between Sony, Toshiba, and IBM to develop the next-generation processor.

The XL family of compilers has grown at IBM beginning in the mid-1980's with development of the earliest IBM POWER-based AIX® systems. Since then, the compilers have been under continuous development, with special attention to producing highly optimized code that fully exploits the POWER and PowerPC range of systems. Recent additions to the XL family support the high-performance Blue Gene®/P and Blue Gene/L supercomputers.

All of this expertise and heritage serving the enterprise business and supercomputing environments is now unleashed to programmers of the Cell/B.E. Architecture, allowing them to take advantage of proven IBM compiler technology.

Description

XL Fortran for Multicore Acceleration for Linux on System p, V11.1 is part of a larger family of IBM Fortran and C/C++ compilers. These compilers are derived from a common code base that share compiler functions and optimization technologies on a variety of platforms and programming languages, such as AIX, selected Linux distributions, z/OS®, z/VM®, Blue Gene/L, and Blue Gene/P operating systems. The common code base, along with compliance with international programming language standards, helps support consistent compiler performance and ease of program portability across multiple operating systems and hardware platforms.

XL Fortran for Multicore Acceleration for Linux on System p, V11.1 is a cross-compiler. Applications are compiled on a System p server, a PowerPC processor-based blade server or a POWER processor-based blade server running Red Hat Enterprise Linux 5.1, with the resulting executable code targeted for a Cell/B.E. Architecture host also running Red Hat Enterprise Linux 5.1.

At the heart of the new Cell/B.E. processor is the PPU. The PPU is a 64-bit processor fully compliant with the Power Architecture standard, and capable of running both operating systems and applications. The Cell/B.E. processor also incorporates a set of eight SPUs into its design. The SPUs are optimized for running computationally intensive applications, operate independently of each other, and can access memory shared between all SPUs and the PPU.

A highly configurable compiler

XL Fortran offers a wealth of features to allow the compiler to be tailored to unique compilation requirements.

Compiler invocation and linking commands: XL Fortran compiles PPU and SPU program code in separate steps using compiler invocation commands targeted specifically for each type of program code. Several versions of PPU-specific compiler invocation commands are provided. Besides ppuxlf , other variants are also provided to help meet special compilation needs. SPU-specific invocation commands are also provided with spuxlf and its variants.

Compiler options: A large selection of compiler options are available to control compiler behavior. Different categories of options help debug applications, optimize and tune application performance, select language levels and extensions for compatibility with non-standard features and behaviors supported by other Fortran compilers, and perform many other common tasks that would otherwise require changing the source code.

XL Fortran allows compiler options to be specified through a combination of environment variables, compiler configuration files, command line options, and compiler directive statements embedded in the program source.

Automated program analysis and tranformations

The XL Fortran compiler is capable of performing sophisticated program analysis and transformation of program code that can result in significant performance improvements with relatively little development effort. For example, the compiler can:

  • Use interprocedural analysis (IPA) to optimize across program files

    IPA can result in significant performance improvements. Interprocedural analysis can be specified on the compile step only or on both compile and link steps in "whole program" mode. Whole program mode expands the scope of optimization to an entire program unit, which can be an executable or shared object.

  • Perform automatic SIMD vectorization of your program code

    When the -qhot=simd compiler option is in effect, the compiler takes certain operations that are performed in a loop on successive elements of an array, and converts them into a call to a vector instruction. This call calculates several results at one time, which is faster than calculating each result sequentially. Applying this suboption is useful for applications with significant image processing demands. Not all loops can be successfully vectorized. However, specifying the -qreport compiler option together with -qhot=simd will cause the compiler to generate diagnostic information that can help improve the efficiency of loops.

  • Automatically generate code overlays for the SPUs

    Specifying -qipa=overlay instructs the compiler to automatically generate code overlays for the SPUs that allow two or more code segments to be loaded at the same physical address as they are needed. This feature lets developers create SPU programs that would otherwise be too large to fit in the local memory store of the SPUs. In addition, the compiler also provides the -qipa=overlayproc and -qipa=nooverlayproc compiler options to give developers direct control over generation of code overlays.

Program optimization

XL Fortran delivers several compiler options that can help control the optimization of application programs. With these options, you can:

  • Select different levels of compiler optimizations
  • Control optimizations for loops, floating point, and other types of operations

XL Fortran also includes specific optimization features specifically tailored to exploit the unique performance capabilities of the Cell/B.E. processors.

Optimizing transformations can give applications better overall execution performance. XL Fortran offers a portfolio of optimizing transformations tailored to various supported hardware. These transformations can:

  • Reduce the number of instructions executed for critical operations
  • Restructure generated object code to make optimal use of the Cell/B.E. Architecture
  • Improve the usage of the memory subsystem

Language standards compliance

The XL Fortran for Multicore Acceleration for Linux on System p compiler supports the following programming language specifications for Fortran:

  • ANSI X3.9-1978 (referred to as FORTRAN 77)
  • ISO/IEC 1539-1:1991(E) and ANSI X3.198-1992 (referred to as Fortran 90 or F90)
  • ISO/IEC 1539-1:1997 (referred to as Fortran 95 or F95)
  • Extension to the Fortran 95 standard
    • Extension specified in SAA® Fortran
    • Industry extensions that are found in Fortran products from various compiler vendors
  • Most of Fortran 2003 standard, except for derived type parameters, but including object-oriented programming, as described in "Enhanced support for Fortran 2003"
  • Common Fortran language extensions defined by other compiler vendors, in addition to those defined by IBM

In addition to the standardized language levels, XL Fortran supports many industry language extensions, including extensions to support vector programming.

Enhanced support for Fortran 2003

XL Fortran supports many Fortran 2003 standard features, including:

  • BIND(C) for portable interoperability with C code
  • Allocatable objects beyond just Fortran 95 arrays
  • Stream I/O support (PPU only)
  • ASSOCIATE and ENUM statements
  • READ with BLANK= and PAD= specifiers (PPU only)
  • WRITE with DELIM= specifier (PPU only)
  • IEEE and Fortran environment modules (PPU only)

This is one of the most complete Fortran 2003 implementation currently available, with Derived Type Parameters being the only major feature not yet implemented.

Fortran 2003 compiler invocations and file types

New compiler invocation commands instruct the compiler to adhere more closely to Fortran 2003 language standards when compiling your applications. The new invocations are:

  • ppuxlf2003, spuxlf2003
  • ppuxlf2003_r (for threaded applications)
  • ppuf2003, spuf2003

In addition to new compiler invocations, this release of XL Fortran also adds support for new filename extensions:

  • .f03
  • .F03 (invokes the C preprocessor before compiling)

Source-code migration and conformance checking

XL Fortran helps protect your investment in your existing Fortran source code by providing compiler invocation commands that instruct the compiler to compile your application code to a specific language level and warn you if it finds constructs and keywords that do not conform to the specified language level. You can also use the -qlanglvl compiler option to specify a given language level, and the compiler will issue warnings if language elements in your program source do not conform to that language level. Additionally, you can name your source files with common filename extensions such as .f77, .f90, f95, or .f03, then use the generic compiler invocations such as ppuxlf or ppuxlf_r to automatically select the language-level appropriate to the filename extension.

Libraries

XL Fortran includes the Mathematical Acceleration Subsystem (MASS).

MASS consists of libraries of mathematical intrinsic functions tuned for optimum performance on the SPUs and PPUs. These libraries offer improved performance over the standard mathematical library routines, are thread-safe, and can be used by Fortran, C and C++ applications. The PPU libraries support both 32- and 64-bit compilations. The MASS library is called automatically when specific levels of optimization are requested by the application. Explicit calls can also be made to MASS library functions regardless of whether optimization options are in effect or not.

Tools and utilities

XL Fortran contains tools and utilities for increased developer productivity including the following:

  • new_install

    After installing XL Fortran for Multicore Acceleration for Linux on System p, V11.1, running this utility will configure the compiler for use on the system.

  • xlf_configure

    This utility can be used for updating the compiler configuration file following updates to the Software Development Kit for Multicore Acceleration or to create customized compiler configuration files.

  • cleanpdf command (PPU only)

    This command is related to profile-directed feedback (PDF) and is used to remove all profiling information from the directory to which profile-directed feedback data is written.

  • resetpdf command (PPU only)

    The current behavior of the cleanpdf command is the same as the resetpdf command, and is retained for compatibility with earlier releases on other platforms.

Diagnostic listings

The compiler output listing can provide important information to aid in development and debugging of applications more efficiently.

Listing information is organized into optional sections that can be included or omitted.

Symbolic debugger support

XL Fortran can be instructed to include debugging information in the compiled objects. This debug information can be examined by the debuggers provided by the IBM Software Development Kit for Multicore Acceleration, V3.0 to help debug application programs.
