Whenever the NAG fl90 has been supplied in compiled form, that form is considered to be the standard library file. The use of all supplied software must be in accordance with the terms and conditions of the Software Licence signed by NAG and each site. Any request to use NAG software on a computer other than the one licensed must be referred to NAG (see Section 6).
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: Compaq Alpha systems operating system: Compaq Tru64 UNIX OSF1 V5.0 or compatible Fortran compiler: Compaq Fortran V5.4A 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: Compaq AlphaServer DS20 operating system: Compaq Tru64 UNIX OSF1 V5.0 (Rev. 1094) Fortran compiler: Compaq Fortran V5.4A-1472 (V5.4A-1472-46B2F) compiler options: -pthread -reentrancy threaded
The entire NAG fl90 library, Release 4, was compiled with optimization level (-O5), except for the following underlying procedures, which had to be compiled with less optimization:
f11aza_9d (-O0) f11cza_9d (-O0) e04ums_8d (-O2)
For further details, refer to other documentation supplied or contact NAG (see Section 6).

libnagfl90.a is the compiled library including the NAG version of the BLAS and LAPACK procedures while libnagfl90_noblas.a does not contain the NAG version of the BLAS and LAPACK procedures and MUST be used with the vendor library CXML (Compaq Extended Math Library).
The examples results given in the directory results are those obtained using libnagfl90.a. Using libnagfl90_noblas.a and CXML may produce slightly different results.
The following shows the directory/file organization of the PDF documentation materials as they will be installed.

compiled library: 19.5 Mb compiled library (without NAG BLAS/LAPACK): 17.0 Mb module information files: 13.0 Mb example program material: 4.3 Mb library documentation files: 0.1 Mb scripts: 0.1 Mb PDF documentation files: 20.2 Mb licensing materials: 21.0 Mb
To install all library material use the Unix tar utility, e.g.
tar xvf /cdrom/fn04.tar(assuming the CD-ROM has been mounted as /cdrom).
The appropriate object library (libnagfl90.a or libnagfl90_noblas.a) should be moved to a directory, such as /usr/lib, in the default search path of the linker, if possible, so that linkage is convenient. Alternatively, a symbolic link could be made, e.g.
ln -s /fndau04dc/libnagfl90.a /usr/lib/libnagfl90.aor
ln -s /fndau04dc/libnagfl90_noblas.a /usr/lib/libnagfl90_noblas.a
The module information files (nag_mod_dir/*.mod) are supplied in pre-compiled module form. They should be moved to a suitable location so that access is convenient, e.g.
mkdir /usr/local/lib/fl90_modules mv nag_mod_dir/* /usr/local/lib/fl90_modulesor, a symbolic link could be made to them, e.g.
ln -s /fndau04dc/nag_mod_dir /usr/local/lib/fl90_modules
The -I"pathname" option should then be specified on each f95 invocation (where "pathname" is /usr/local/lib/fl90_modules) to tell the compiler where to find the modules.
Alternatively, the files may be moved to the same directory as the pre-defined modules supplied with the compiler.
The scripts nagexample and nagexample_noblas 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.
The man page, which directs users to the HTML form of the Users' Note, should be moved to a directory in the man search path, e.g.
cd doc mv nag_fn_un.3 /usr/man/man3
First, you need to determine the hostid of the system. This may be achieved by running the FLEXlm utility program 'lmutil' provided in fndau04db/license/bin/alpha_u3, using the argument 'lmhostid'. For example, if you are in the directory fndau04db you can use:
Next, contact a NAG Response Centre and request a license key. Customers in North America should contact NAG Inc, all others should contact NAG Ltd; in both cases you will need to quote your NAG site reference, NAG product code (FNDAU04DB) and the hostid you have just determined.
For the fl90, NAG will provide you with an 'uncounted license key' for use on a specific machine. This will consist of a FEATURE or INCREMENT line for the licensed product, for example:
FEATURE NAG_FN NAG 4.000 30-nov-2002 0 CBDA2041DC1BC45D2B68 "DAUB," 80896b27(which would enable an unlimited number of instances of version 4 of the application NAG_FN, until the date specified, on the system with hostid 80896b27 only). Note that the line may be continued by escaping the newline character with '\'.
Once you have obtained the license key, store the text of it in a file, say /usr/local/lib/nag/license.dat - if you already have any FLEXlm licenced products on your system, you will need to add the new license key as an extra line in your existing file of FLEXlm license keys; you can determine the location of this with
If the environment variable LM_LICENSE_FILE is not already set, you must set it to the full pathname of the file of FLEXlm license keys; this variable will be accessed by the NAG application to confirm that a valid license exists.
For example, in the C-shell, LM_LICENSE_FILE may be set by typing:
setenv LM_LICENSE_FILE /usr/local/lib/nag/license.dator, in the Bourne shell, by:
LM_LICENSE_FILE=/usr/local/lib/nag/license.dat export LM_LICENSE_FILE
No other actions are required to install an uncounted license.
tar xvf /cdrom/pdf.tar(assuming the CD-ROM has been mounted as /cdrom).
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.
The following material should also be made accessible to users:
libnagfl90.a or libnagfl90_noblas.a
module information files:
nag_mod_dir/*.modexample program material:
scripts/nagexample or scripts/nagexample_noblas
pdf documentation files
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 provided, in PDF form, with this implementation. Further information is contained in the Readme file on the distribution medium.
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 please quote your NAG site reference and NAG product code (FNDAU04DC).
The NAG websites are an information service providing items of interest to users and prospective users of NAG products and services. The information is reviewed and updated regularly and includes implementation availability, descriptions of products, downloadable software, product documentation and technical reports.
