This paper introduces the necessary background for developers who are migrating to the Intel Visual Fortran Compilers from Compaq Visual Fortran. It discusses changes in behavior, and it highlights source and build changes that may be needed as part of that migration. Introduction The Intel Visual Fortran product can coexist on a system with CVF, and you can continue using the older product if you wish. Intel® Visual Fortran Compiler 10.0 for Windows* integrates However, Intel Visual Fortran does not integrate with Microsoft with Microsoft developer tools to provide very high levels of Visual Studio 6 environment used by CVF, whereas CVF does not optimization for the full spectrum of Intel® processor technologies. integrate with the 2002 and later versions of Microsoft Visual In addition to performance and industry-compatibility gains, Studio. The Intel and Compaq products install into separate folder this version provides full support for IA-2, Intel® 64 (formerly trees and use separate registry variables. Intel® EM64T) and IA-64 (Intel® Itanium) architecture processors All Fortran sources must be recompiled with Intel Visual Fortran including the latest Intel multi-core processors, as well as support Compiler; you cannot use CVF-compiled objects, modules, or static for previous generations of processors. libraries with Intel Visual Fortran Compiler. You can, however, use CVF- In most cases, you can rebuild existing Compaq Visual Fortran built dynamic link libraries (DLLs) with applications compiled with the (CVF) applications with the new compilers without source Intel Visual Fortran Compiler, as long as you do not try to share input/ changes, but some applications may need minor coding changes, output units across the two environments. Note also that third-party and build methods may need minor adjustments.

Intel Visual Fortran Compiler supports all of the CVF language syntax, including extensions from Digital Equipment Corporation Product Compatibility (DEC) Fortran and Microsoft Fortran PowerStation* 4. All CVF If you already have installed Microsoft Visual Studio 2005* or library routines are supported, including those from the QuickWin Microsoft Visual Studio .NET 200*, Intel Visual Fortran will and Portability libraries, as are all of the system-interface modules. integrate into that Visual Studio development environment allowing In most cases, a simple rebuild of the application with the Intel you to create, build and debug Fortran and mixed-language compiler is all that is needed.

Visual Studio installed, Intel Visual Fortran will install Microsoft Features Not Supported Visual Studio Premier Partner Edition* to provide a rich development Intel Visual Fortran supports all of the language syntax supported environment for Fortran programming on IA-2 and Intel® 64 by CVF. However, some of the CVF product features are not systems. (Note that some license types of Intel Visual Fortran do supported by Intel Visual Fortran.

  • Data Layout Optimization Techniques for Modern and Emerging Architectures
    DATA LAYOUT OPTIMIZATION TECHNIQUES FOR MODERN AND EMERGING ARCHITECTURES DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Qingda Lu, B.E., M.S. ***** The Ohio State University 2008 Dissertation Committee: Approved by Dr. P. Sadayappan, Adviser Dr. Xiaodong Zhang Adviser Dr. J. Ramanujam Graduate Program in Dr. Atanas Rountev Computer Science and Engineering c Copyright by ° Qingda Lu 2008 ABSTRACT The never-ending pursuit of higher performance is one fundamental driving force of computer science research. Although the semiconductor industry has fulfilled Moore’s Law over the last forty years by doubling transistor density every two years, the effectiveness of hardware advances cannot be fully exploited due to the mismatch between the architectural environment and the user program. Program optimization is a key to bridge this gap. In this dissertation, instead of restructuring programs’ control flow as in many previous efforts, we have applied several new data layout optimization techniques to answer many optimization challenges on modern and emerging architectures. In particular, the developed techniques and their unique contributions are as follows. We describe an approach where a class of computations is modeled in terms of con- • stituent operations that are empirically measured, thereby allowing modeling of the overall execution time. The performance model with empirically determined cost components is used to perform data layout
