Installer's Note



Contents


1. Introduction

This document is essential reading for whoever is responsible for the installation of the NAG fl90 implementation specified in the title. The installer will be supplied with a printed copy of this document. Both this (in.html) and the Users' Note (un.html) are supplied in the doc directory on the distribution medium.

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).

For each of the following Instruction Set Architecture (ISA) and Application Binary Interface (ABI) combinations:

   MIPS  IV ISA / n64 ABI
   MIPS III ISA / n64 ABI
   MIPS  IV ISA / n32 ABI
   MIPS III ISA / n32 ABI
a module directory and two compiled libraries are provided by NAG:

The example results given in the directory examples/result are those obtained using libnagfl90_64_mips4.a. Using another ISA/ABI combination or a library without the NAG version of the BLAS and LAPACK procedures, and the corresponding libcomplib.sgimath library, may produce slightly different results.

4. Installation

4.1. Library Installation

To install all library material use the Unix tar utility, e.g.

cd /opt
tar xvf /cdrom/fn04.tar
(assuming the CD-ROM has been mounted as /cdrom).

Materials for specific ISA/ABI combinations can also be installed using tar. For example, if only the materials for MIPS IV / n64 are required,

cd /opt
tar xvf /cdrom/fn04.tar fnsg604dbl/doc fnsg604dbl/libnagfl90_64_mips4* \
                        fnsg604dbl/nag_mod_dir_64_mips4 \
                        fnsg604dbl/examples fnsg604dbl/scripts
will install (from /cdrom) the library documentation, the appropriate compiled libraries and module directory, the examples and the scripts.

It is advisable to keep the libraries in the installed directory /opt/fnsg604dbl and make symbolic links libnagfl90.a and libnagfl90_noblas.a to them from the appropriate system library directory, where the linker (ld) will find them. For example, if only the MIPS IV / n64 materials have been installed:

ln -s /opt/fnsg604dbl/libnagfl90_64_mips4.a /usr/lib64/mips4/libnagfl90.a
ln -s /opt/fnsg604dbl/libnagfl90_64_mips4_noblas.a \
         /usr/lib64/mips4/libnagfl90_noblas.a
(the system directory /usr/lib64/mips4 is appropriate for the MIPS IV / n64 libraries;
for the MIPS III / n64 libraries the appropriate directory is /usr/lib64/mips3 ;
for MIPS IV / n32 it is /usr/lib32/mips4 ;
and for MIPS III / n32, /usr/lib32/mips3).

The module information files (e.g. nag_mod_dir_64_mips4/*) are supplied in pre-compiled module form. They should be moved to a suitable location so that access is convenient; for example:

mkdir /usr/local/lib/fl90_modules
mv nag_mod_dir_64_mips4/* /usr/local/lib/fl90_modules
or, a symbolic link could be made to them, e.g.
ln -s /opt/fnsg604dbl/nag_mod_dir_64_mips4  /usr/local/lib/fl90_modules

The -Ipathname option should then be specified on each f90 invocation (where pathname is /usr/local/lib/fl90_modules) to tell the compiler where to find the modules.

If material for more than one ISA/ABI combination has been installed, the names chosen for the location of the modules must reflect this; in this case it may be useful to retain names reflecting the original NAG names, for example:

ln -s /opt/fnsg604dbl/nag_mod_dir_64_mips4 \
         /usr/local/lib/fl90_modules_64_mips4
However, also setting up the simpler name, fl90_modules, for the default ISA/ABI combination of your system may be beneficial for the majority of users.

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 and modified to reflect the local installation and the ABI/ISA combination used (or preferred). Their protection should be 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

4.1.1. License Management

The use of the NAG fl90 Library is controlled by the FLEXlm network license management system (FLEXlm is a registered trademark of Globetrotter Software Inc). This release of the NAG fl90 Library uses version 7.2g of FLEXlm.

In order to enable the software, NAG will issue you with a license key. The license key is a simple text file (usually called license.dat), containing details of the software that will be enabled.

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

FEATURE NAG_FN NAG 4.000 30-nov-2002 0 CBDA2041DC1BC45D2B68 "ANY" DEMO
Specifically, it does not have any lines starting with the word SERVER 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.

To apply for a longer term license key, contact one of the NAG Response Centres quoting the product to be licensed and the FLEXlm hostid for the computer. To obtain the FLEXlm hostid, select the appropriate lmutil program from the platform specific directory under the license/bin/ subdirectory, and run it with argument lmhostid. For example, if you are in the directory fnsg604dbl you can use:

./license/bin/sgi64_u6/lmutil lmhostid

On systems without an ethernet card, use the arguments lmhostid -long.

Once you have obtained the license key, store the text of it in a file, say /usr/local/lib/nag/license.dat.

The location of this 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 /usr/local/lib/nag/license.dat
or in the Bourne shell, type:
LM_LICENSE_FILE=/usr/local/lib/nag/license.dat
export LM_LICENSE_FILE
No 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 supplied in the license/htmlman/flexuser/ subdirectory.

4.2. PDF Documentation Installation

To install all PDF documentation material, use the Unix tar utility, e.g.
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.

4.3. Checking Accessibility

The installer should ensure that the advice given to users in Section 3.1 of the Users' Note (un.html) is suitable for the installation; this advice will require modification if, for example, material for more than one ISA/ABI combination has been installed. The suitability of the advice can be checked by following it to run a few example programs. The installation can also be tested using the scripts nagexample and nagexample_noblas.

4.4. Release to Users

The Users' Note (un.html) should be checked and amended as necessary (particularly Section 3.1). It can then be made available to users directly, or be absorbed into local access information.

The following material should also be made accessible to users:

compiled libraries:

libnagfl90_[32|64]_mips[3|4].a
libnagfl90_[32|64]_mips[3|4]_noblas.a
module information files:
nag_mod_dir_[32|64]_mips[3|4]/*.mod
example program material:
examples/source/*.f90
examples/data/*.dat
examples/results/*.r
scripts/nagexample
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.

4.5. Maintenance Level

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

5. Documentation

Each supported NAG fl90 site is currently provided with a printed copy of the NAG fl90 Manual (or Update). Additional copies are available for purchase; please refer to the NAG documentation order form (available on the NAG websites, see Section 6 (c)) for details of current prices.

On-line documentation is provided, in PDF form, with this implementation. Further information is contained in the Readme file on the distribution medium.
