Installer's Note


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 available together with the Users' Note (un.html) on the distribution medium.

Your attention is drawn to the terms and conditions of the Software License regarding the use of NAG software. Requests for information about the availability of other implementations must be referred to NAG.

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:          Intel(R) 64 systems and compatible (including AMD64)
operating system:  Linux 2.6.27 (glibc-2.9-3) and compatible
Fortran compiler:  PGI Fortran Compiler pgf90 13.6 and compatible

2.2. Derivation

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

hardware:         Intel Xeon E5405 2.00GHz
operating system: Linux (Fedora release 10 (Cambridge))
                  with glibc-2.9-3
Fortran compiler: PGI Fortran Compiler pgf90 13.6-0 64-bit target on x86-64 Linux -tp penryn

This library has been tested on the following systems:

hardware:         Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz
operating system: Linux 3.9.8-100.fc17 (Fedora release 17 (Beefy Miracle))
                  with glibc-2.15
Fortran compiler: PGI Fortran Compiler pgf90 13.6 64-bit target on x86-64 Linux
hardware:         Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz
operating system: Linux 3.9.8-100.fc17 (Fedora release 17 (Beefy Miracle))
                  with glibc-2.15
Fortran compiler: PGI Fortran Compiler pgf90 13.4 64-bit target on x86-64 Linux
hardware:         AMD Opteron(tm) Processor
operating system: Linux
                  with glibc-2.11
Fortran compiler: PGI Fortran Compiler pgf90 13.6 64-bit target on x86-64 Linux

The NAG Fortran Library, Mark 24, was compiled with the highest level of optimization that enabled the functionality provided by the library to be verified and validated.

This library has been tested using the Basic Linear Algebra Subprograms (BLAS) and Linear Algebra PACKage (LAPACK) routines provided by NAG (see the Chapter Introductions for F06, F07, F08 and F16 in the NAG Mark 24 Library Manual, which we will refer to as the Library Manual).

The library has also been tested with version 5.3.1 of the AMD ® Core Math Library for Linux (ACML) which is supplied as a part of this product (see Section 3.1).

3.2. File Sizes

The files require approximately the following disk space:

  Library software:  867 MB
  Library Manual:    240 MB

4. Installation

4.1. Installation of Library Software and Manual

If you have downloaded the Library materials from our website as a tar gzip file (fll6a24dpl.tgz), cd to the directory where the file is located and extract the installation materials using the following commands:

  gunzip fll6a24dpl.tgz
  tar xvf fll6a24dpl.tar
This will extract the files, fl24.tar, lic_agr.txt, in.html and un.html.

If you have downloaded the Library Manual as a tar gzip file (mk24_doc.tgz) run the command

  gunzip mk24_doc.tgz
to extract the file mk24_doc.tar.

4.1.1. Installation Procedure

You can install the materials from the download directory or CD/DVD by executing the Bourne Shell script install in a command window as:
If you are logged in as root then by default, the materials will be installed in /opt/NAG/ or /usr/local/NAG/ depending on your system. However, you may choose a different location. In this document we refer to the directory /opt/NAG/fll6a24dpl or /usr/local/NAG/fll6a24dpl as [INSTALL_DIR]. This convention is also used in the Users' Note (un.html).

The directory [INSTALL_DIR]/scripts contains several scripts to show how to use the pre-compiled modules and the libraries provided with this implementation. See Users' Note, Section 3.3. Subsequent to the installation, if you move this product to some other location (or use modules in a different location) then these scripts must be changed to reflect that fact.

Each library is provided in both static and shareable format. You also have a choice of libraries; self-contained libraries which use NAG supplied BLAS and LAPACK or libraries which require the use of vendor supplied BLAS and LAPACK.

The install script can install the Library Manual in the same location as the NAG Library material or at some other location of your choice.

You may wish to move the Library Manual to the same location as that for other NAG products. You are encouraged to make it readily available to users.

4.1.2. License Management

The use of this product is controlled by the Kusari license management system. This release of the Library uses version 2.2-58 of Kusari.

In order to enable the software, NAG will issue you with a license key. The license key is contained in a text file consisting of details of the software that will be enabled.

To request a license key, run the program khostid located in the license/bin/linux_x64/ subdirectory of the software distribution. This utility must be run from a command prompt. Return the information that it displays, together with the product code (in this case FLL6A24DPL), by e-mail (or FAX) to NAG. Alternatively, direct the output from this utility to a file and send both the file and the product code to NAG.

A short term (demonstration or trial) license key contains one or more lines like the following:

FLL6A24DP TRIAL 2012/11/12 "EMnxidA3oeoj0F1Yvi5ibxPjB7"
Specifically, it has a line containing the word TRIAL. Longer term license keys must be locked to a specific computer, i.e. they will enable the software on one computer only. These license keys include the word NODE instead of the word TRIAL above.

Once you have obtained one of the above license keys, the easiest way to install it is to store the text in a file,

The license software in this implementation automatically looks for these particular files and reads the first one found, so no other action is necessary. Alternatively, store the license in a file with a name and location of your choice, say,
The location of the license file, if it is not one of the default places listed above, must be made known to the NAG application by setting the environment variable NAG_KUSARI_FILE to the full pathname of the file before the application is invoked.

For example, in the C-shell, type:

  setenv NAG_KUSARI_FILE [INSTALL_DIR]/license.lic
or in the Bourne shell, type:

Further details about Kusari and how it may be configured to suit your local circumstances (e.g. how to install the license key on a server) are included in the Kusari License Management documentation in the license/doc/ subdirectory of the software distribution. See also the Kusari FAQ:

4.2. Release to Users

The Users' Note (doc/un.html) should be checked and amended as necessary (particularly Sections 3.1, 3.3 and 5). Advice on accessing the library (see Users' Note, Section 3.1) can be checked by running a few example programs following that advice; a suitable sample would be D01AUF, E04UCA and F07ADF. The installation can also be tested using the scripts nag_example* (see Users' Note, Section 3.3). The Users' Note (doc/un.html) 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 nagdoc_fl24 directory contains the Library Manual.

compiled libraries:

ACML libraries supplied by NAG
interface block files:
example program material:
C and C++ header material:

Note that the example material has been adapted, if necessary, from that published in the Library Manual, so that programs are suitable for execution with this implementation with no further changes (but see Section 3.3 of the Users' Note 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.

4.3. Further Information

4.3.1. Maintenance Level

The maintenance level of the Library can be determined by compiling and executing the example that calls A00AAF, or you could call one of the nag_example scripts with the argument a00aaf. See Users' Note, Section 3.3. This example prints out details of the implementation, including title and product code, compiler and precision used, mark and maintenance level.
