Installer's Note



Contents


1. Introduction

This Installer's Note is essential reading for whoever is responsible for the installation of this implementation of the NAG Fortran Library. It is supplied in printed form to accompany the software, and is also available together with the Users' Note (un.html) in the doc folder on the distribution medium.

Your attention is drawn to the terms and conditions of the Software Licence regarding the use of NAG software. Any request to use this software other than on the licensed computer must be referred to NAG, as should requests for information about the availability of other implementations.

2. Implementation Provided

2.1. Applicability

This implementation is a compiled, tested, ready-to-use version of the NAG Fortran Library that is considered suitable for operation on the computer systems detailed below:

hardware:         32-bit Intel systems and compatible
operating system: Windows 98/NT/ME/2000/XP
Fortran compiler: Intel Fortran for 32-bit applications

2.2. Derivation

This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:

hardware:         Intel Xeon
operating system: Windows 2000
Fortran compiler: Intel Fortran for 32-bit applications v7.0, Build 20030129Z
compiler options: /MT /O3

The option /MT causes an application using the NAG Library to be linked with the static, multithread runtime libraries libF90mt.lib, libIEPCF90mt.lib, libmmt.lib and libcmt.lib.

The entire NAG Fortran Library, Mark 20, was compiled with full optimization (/O3), except for the following routines, which had to be compiled at lesser optimization levels:

D06DAF (/Od)         F08PSZ (/Od)         G08EDF (/Od)         Y90RBF (/Od)
F04FEF (/Od)         G03FAZ (/Od)         X03AAY (/O3 and /Op)

Two static libraries are provided. One contains all the routines mentioned in the NAG Fortran Library Manual. The second allows the use of third party, processor tuned versions of the Basic Linear Algebra Subprograms (BLAS) and linear algebra routines (LAPACK). (Refer to the Chapter Introductions for F06, F07 and F08 in the NAG Fortran Library Manual for more information about the BLAS and LAPACK.)

NAGBL.LIB


Contains NAG versions of all BLAS and LAPACK routines by both their BLAS/LAPACK names and NAG F06/F07/F08 names.


NAG.LIB


Contains NAG versions of BLAS/LAPACK by their NAG F06/F07/F08 names only. The BLAS/LAPACK names must be resolved from some other library, for example Intel MKL.

NAG.LIB has been tested with Intel MKL version 6.0 beta (December 2002). Please see the Intel web site for further information about MKL (http://www.intel.com/software/products/mkl).

3. Distribution Medium

The software is ordinarily distributed on CD-ROM.

4. Installation

4.1. Library Installation

You should have Administrator privileges to install this software.

The CD contains an InstallShield SETUP executable file (.EXE) for the library implementation and a Windows Installer package for the manual (manual.msi). Installation of the manual is optional. It may be viewed from the CD or installed onto local disk as described in Section 4.2.

To install the Library insert the CD into your CD drive to display the NAG Library Setup Menu. If the Setup Menu does not display, run e:\setup.exe where e is the drive letter for your CD drive. Select Install the library, Windows Installer will lead you through the installation.

Installation of the Library requires a license key, which will be provided by NAG. This will either be a `Trial' key, which will allow you to try out the library for a limited period of time, or a `Fully Paid' key which enables use of the library indefinitely on a specific workstation. If you do not have a key, Installer will generate a file (usually saved as C:\NagKeyRqst.txt), which may be E-mailed or faxed to NAG (see Appendix). In return NAG will send you a valid license key.

Should you need to re-install the license key, (for example to replace a trial key), locate an run the utility flw3220dbl\bin\key_inst.exe.

Once in possession of a valid license key, begin the installation process again. You will be prompted for the license key. Once this has been entered the process will continue.

If the Fortran compiler is not installed in the folder C:\Program Files\Intel\Compiler70 the environment variable COMP_DIR in the file ...\FL20\flw3220dbl\batch\envvars.bat must be modified to show the path to the folder in which it is installed.

Installation will create the shortcut

Start | Programs | Numerical Algorithms Group | FL20 | Intel Fortran with NAG static Lib. Command Prompt

which is originally set to launch the command processor CMD.EXE. On Windows 98 and Me systems, the shortcut must be modified as follows (to modify a shortcut, right-click the Start button, and navigate to the shortcut, right-click it, then select Properties | Shortcut):

  1. Change the command interpreter from ...\CMD.EXE to C:\WINDOWS\COMMAND.COM
  2. Add the argument /E:3072 before the argument /K
  3. Change the last argument from
       ""C:\Program Files\NAG\FL20\flw3220dbl\batch\envvars.bat""
    to
       "C:\PROGRA~1\NAG\FL20\flw3220dbl\batch\envvars.bat"

The shortcut may then be used to start a command prompt window with the correct environment variables to use the Intel compiler with the NAG Fortran Library.

4.2. PDF Documentation Installation

It is not necessary to install the Library manual. Users may access it directly on the distribution CD, or it may be installed on a diferent workstation or server.

To install the Library manual in PDF insert the CD into your CD drive to display the NAG Library Setup Menu. If the Setup Menu does not display, run e:\setup.exe where e is the drive letter for your CD drive. Select Install the library manual. Alternatively you could run e:\manual.msi. Windows Installer will lead you through the installation.

You may wish to move the PDF documentation files to the same location as that for other NAG products. You are encouraged to make them readily available to users, but in such a way that they are not generally accessible from outside your site.

If you do not already have a copy of Adobe Acrobat Reader for your platform, a free copy can be downloaded from http://www.adobe.com/. Please check this site for availability of a reader for your platform.

Please note that if you are using Adobe Acrobat 4.0 or earlier you might experience some problems when printing documents that contain non-standard characters, such as integral signs, square roots and large brackets. These characters will print correctly using Adobe Acrobat 5.0.

The HTML form of the Essential Introduction contains some mathematical characters that are displayed as question marks by releases of Netscape earlier than 6, but these are displayed correctly by Netscape 6 and Internet Explorer. They may also be viewed via the PDF.

If using Netscape, it might be necessary to re-install Acrobat to ensure that the Acrobat plug-in has been installed. If the plug-in has not been installed, Netscape may copy PDF files to a temporary folder, and then not be able to navigate from there.

4.3. Release to Users

The Users' Note (doc\un.html) should be checked and amended as necessary (particularly Sections 3.1 and 5.). Advice on accessing the library in Section 3.1 can be checked by running a few example programs following that advice; a suitable sample would be A02AAF, D01AUF, G05LFF and X03AAF. The installation can also be tested using the script nagex.bat. The Users' Note should then be made available to users directly, or be absorbed into local access information.

The following material should also be made accessible to users:

documentation files:

The FL20\Manual folder contains the online documentation. This should be made available to users, in addition to the following:

doc\blas_lapack_to_nag
doc\nag_to_blas_lapack
compiled libraries:
lib\nag.lib
lib\nagbl.lib
interface block files:
interface_blocks\*.mod
example program material:
examples\source\??????e.f
examples\data\??????e.d
examples\results\??????e.r
batch\nagex.bat

Note that the example material has been adapted, if necessary, from that published in the NAG Fortran Library Manual, so that programs are suitable for execution with this implementation with no further changes (but see Section 4.4.2 for comments about possible differences in results obtained). Making the example material directly available to users provides them with easily adaptable templates for their own problems.

4.4. Further Information

4.4.1. Output Unit Dependencies (X04)

Certain NAG routines use explicit WRITE statements to produce output directly. The choice of output unit used can be controlled by using X04AAF and X04ABF, described in the NAG Fortran Library Manual. The defaults for this implementation are given in the Users' Note.

4.4.2. Example Programs

The example results distributed were generated using NAGBL.LIB and the software described in Section 2.2. These example results may not be exactly reproducible if the example programs are run in a slightly different environment (for example, a different Fortran compiler, a different compiler library, different arithmetic hardware, or a different set of BLAS or LAPACK routines). The results which are most sensitive to such differences are: eigenvectors (which may differ by a scalar multiple, often -1, but sometimes complex); numbers of iterations and function evaluations; and residuals and other "small" quantities of the same order as the machine precision.

The "example programs" for the routines in the F06 chapter are not typical example programs and they are not in the Library Manual. They are test programs, which are supplied to sites for use in an installation test of the Library. Some of them take much longer to run than other example programs. Routines which are equivalent to BLAS, are tested twice: once when called by their NAG F06 names, and once when called by their BLAS names.

4.4.3. Maintenance Level

The maintenance level of the library can be determined by writing a simple program to call A00AAF, which prints out details of the implementation, including title and product code, compiler and precision used, mark and maintenance level.
