Whenever the NAG fl90 has been supplied in compiled form, that form is considered to be the standard library file.
Your attention is drawn to the terms and conditions of the Software License 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.
This implementation is a compiled, tested, ready-to-use version of NAG fl90 that is considered suitable for operation on the computer systems detailed below:
hardware: IBM Power5 32-bit systems or compatible
(including Power3 and power4)
operating system: AIX v5.3 or compatible
Fortran compiler: IBM xlf90 v9.1 or compatible
For information about implementations of NAG fl90 for use on other computer systems please contact NAG.
This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:
hardware: IBM Power5 system operating system: AIX v5.3 Fortran compiler: IBM xlf90 version 9.1.0.0 compiler options: -O3 -qstrict -w -u -qarch=pwr3 -qtune=pwr4 -qnosave -qthreaded
The entire NAG fl90 library, Release 4, was compiled with optimization level (-O3 -qstrict), except for the following procedure, which had to be compiled with less optimization level:
e04ncy_8d (-O2) e04ncz_8d (-O2) f02mef_9d (-O0) f07hox_9d (-O0) f08maf_9d (-O0) f08mpf_9d (-O0) f08qkf_9d (-O0) f08qxf_9d (-O0) f11uaf_9d (-O0) g03acf_9d (-O0)The Library can be used with or without the compiler flag -qextname.
This library has been tested using the Basic Linear Algebra Subprograms (BLAS) and linear algebra routines (LAPACK) provided by NAG.
The library has been also tested with IBM BLAS and the Engineering and Scientific Subroutine Library ESSL v4.2.

./install.shBy default, the materials will be installed in /opt/NAG/ or /usr/local/NAG/ depending on your system. The installer may choose a different location. In this document we refer to the directory /opt/NAG/fnai304dal or /usr/local/NAG/fnai304dal as [INSTALL_DIR].
The directory [INSTALL_DIR] is referenced in the Users' Note (un.html).
The directory [INSTALL_DIR]/scripts contains one or more scripts to show how to use the libraries provided with this implementation. See Users' Note, Example Programs. Subsequent to the installation, if the installer moves the library to some other location then these scripts must be changed to reflect that fact.
To simplify access to the libraries you may wish to create symbolic links in a system location such as /usr/lib pointing at the installed libraries. They would then be in the default search path of the linker during the link phase, and be available for execution at run time (in the case of shareable libraries). Note that if both the static and shareable version of a library are placed in a directory then the shareable version is usually used by default.
The install script can install the Library documentation material in the same location as the NAG Library material or at some other location of the installer's choice.
You may wish to move the Library documentation files to the same location as that for other NAG products. You are encouraged to make them readily available to users.
The module information files (nagfl90_modules/*.mod) are supplied in pre-compiled module form.
The
Alternatively, you could update the IBM xlf configuration file
(the default is /etc/xlf.cfg) or create your own copy of
xlf.cfg to include the
In the scripts provided and in the Users' Note (un.html) we use files with extension f90 and invoke the compiler using xlf90_r. Please ensure that suffix = f90 is part of the setting in the "xlf90_r" section within the IBM xlf configuration file to be used (the default is /etc/xlf.cfg).
Use the tar utility to extract the materials, e.g.
tar xvf /cdrom/fn04.tar(assuming the CD-ROM has been mounted as /cdrom).
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. You may choose to install some or all of the libraries.
To simplify access to the libraries you may wish to create symbolic links in a system location such as /usr/lib pointing at the installed libraries. Then they would be in the default search path of the linker during the link phase, and be available for execution at run time (in the case of shareable libraries). Note that if both the static and shareable version of a library are placed in a directory then the shareable version is usually used by default.
To install the Library documentation material manually, use the tar utility, e.g.
tar xvf /cdrom/fn04_doc.tar(assuming the CD-ROM has been mounted as /cdrom).

The directory [INSTALL_DIR]/scripts contains one or more scripts to show how to use the libraries provided with this implementation. These scripts refer to the local directory containing the example programs. The files should be copied to (for example) /usr/local/bin, modified to reflect the local installation, and their protection set to world execute.
In the scripts provided and in the Users' Note (un.html) we use files with extension f90 and invoke the compiler using xlf90_r. Please ensure that suffix = f90 is part of the setting in the "xlf90_r" section within the IBM xlf configuration file to be used (the default is /etc/xlf.cfg).
In order to enable the software, NAG will issue you with a license key. The license key is a simple text file containing details of the software that will be enabled.
To request a license key, run the program key_rqst located in the license/bin/rs6000_u3/ subdirectory of the software distribution. This utility does not have a GUI and must be run from a command prompt. Complete the form that it displays and e-mail (or FAX) it to NAG.
A short term (demonstration or trial) license key contains one or more lines like the following:
FEATURE NAG_FN NAG 21.000 10-sep-2005 0 CBDA2041DC1BC45D2B68 "ANY" DEMOSpecifically, it has a line starting with the word FEATURE and is referred to here as an uncounted license key. Longer term uncounted 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 FLEXlm hostid of the computer instead of the word DEMO above.
Once you have obtained the license key, store the text of it in a file, say [INSTALL_DIR]/license.lic.
For an uncounted license, the location of the license file must be made known to the NAG application by setting the environment variable LM_LICENSE_FILE to the full pathname of the file before the application is invoked.
For example, in the C-shell, type:
setenv LM_LICENSE_FILE [INSTALL_DIR]/license.licor in the Bourne shell, type:
LM_LICENSE_FILE=[INSTALL_DIR]/license.lic export LM_LICENSE_FILENo other actions are required to install an uncounted license.
Further details about FLEXlm and how it may be configured to suit your local circumstances are included in the FLEXlm End Users Guide.
The following material should also be made accessible to users:
documentation files:
The nagdoc_fn04 directory contains the online documentation. This should be made available to users, in addition to the following:
compiled libraries:
libnagfl90_nag.a libnagfl90_nag.so libnagfl90_essl.a libnagfl90_essl.somodule information files:
nagfl90_modules/*.modexample program material:
examples/source/*.f90 examples/data/*.dat examples/results/*.r scripts/nagfl90_example*
Note that the example material has been adapted, if necessary, from that printed in the NAG fl90 Manual, so that programs are suitable for execution with this implementation with no further changes. Making the example material directly available to users provides them with easily adaptable templates for their own problems.
On-line documentation is bundled with this implementation. Please see Section 4.
The NAG Response Centres are available for general enquiries from all users and also for technical queries from sites with an annually licensed product or support service.
The Response Centres are open during office hours, but contact is possible by fax, email and phone (answering machine) at all times.
When contacting a Response Centre it helps us deal with your enquiry quickly if you can quote your NAG site reference and NAG product code (in this case FNAI304DAL).
