IBM extends the XL Fortran family to Linux on the pSeries platform.
XL Fortran (XLF) V8.1 and XL Fortran Run-Time Environment (XLF RTE) V8.1 support Linux on the pSeries platform such as SuSE Linux Enterprise Server 8 (SLES 8) for pSeries running on the IBM PowerPC® family of processors.
XLF V8.1 for Linux on pSeries is based on the mature compiler technology of XLF for AIX® and is fully compliant with FORTRAN 77, Fortran 90, and Fortran 95 standards. It also supports both IBM and industry extensions. In addition, this program provides full support for the OpenMP Fortran API V2.0. With 32-bit and 64-bit optimization supported in the compiler, XLF V8.1 for Linux on pSeries generates highly optimized code for PowerPC processors, including POWER4 architecture.
XLF V8.1 for Linux on pSeries
The XLF compiler is now available for Linux on pSeries. XLF for Linux on pSeries is based on the mature compiler technology of XLF for AIX, and currently supports SLES 8 for pSeries.
FORTRAN 77, Fortran 90, and Fortran 95 Standards: XLF V8.1 for Linux on pSeries is a native and highly optimized compiler that exploits pSeries architecture and fully complies with FORTRAN 77, Fortran 90, and Fortran 95 standards. It partially supports draft Fortran 2000 standard features. It also supports IBM and industry extensions from various compiler vendors.
Supported draft Fortran 2000 features include:
OpenMP: 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.
XLF V8.1 for Linux on pSeries provides full support for the OpenMP Fortran API V2.0. For more information on the OpenMP Fortran API V2.0, visit:
Use the xlf_r, xlf90_r or xlf95_r command to compile XL Fortran SMP programs. For the compiler to recognize the SMP directives and activate parallelization, you must also specify the -qsmp option.
32-Bit and 64-Bit Support: Use XLF for Linux on pSeries to develop both 32-bit and 64-bit mode applications. XLF V8.1 for Linux on pSeries provides 64-bit pointer and 64-bit addressability. High optimization levels (-O5, -O4 and -qhot), interprocedural analysis, and parallelization are supported for 64-bit mode applications.
Exploiting the PowerPC Architecture: XLF for Linux on pSeries supports POWER3, POWER4, and PowerPC architectures. Use compiler options -qarch and -qtune to instruct the compiler to generate code specific to an architecture. 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.
Asynchronous I/O: XLF for Linux on pSeries supports asynchronous I/O. Asynchronous I/O can be used to improve the performance of applications that perform input and output of large amounts of data. Asynchronous I/O makes it possible for other program statements to be executed while the data transfer is taking place.
Port or Migration Support: The XLF compiler helps you port or migrate source code among Fortran compilers by providing full FORTRAN 77, Fortran 90, and Fortran 95 language support and selected language extensions (such as intrinsic functions, data types) from many different compiler vendors.
The xlf, xlf_r, f77, and fort77 commands provide maximum compatibility
with existing FORTRAN 77 programs. The default options provided with the
xlf90 and xlf90_r commands give access to the full range of Fortran 90
language features. The default options provided with the xlf95 and
xlf95_r commands give access to the full range of Fortran 95 language
IBM XL Fortran Run-Time Environment (RTE) V8.1 for Linux on pSeries
XLF RTE V8.1 for Linux on pSeries provides a run-time environment to support library modules, asynchronous I/O, threadsafe I/O, and I/O services and utilities.
