Whenever the NAG Fortran Library 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 the NAG Fortran Library that is considered suitable for operation on the computer systems detailed below:
hardware: all SPARC systems operating system: Solaris 2.6 or compatible Fortran compiler: Sun Fortran 77 v5.0 or compatible
For information about implementations of the NAG Fortran Library for use on other computer systems please contact NAG.
This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:
hardware: Sun Ultra Enterprise operating system: Solaris 2.6 Fortran compiler: Sun Fortran 77 v5.0 compiler options: -O4 -fsimple=1 -dalign
The entire NAG Fortran Library, Mark 19, was compiled with full optimization (-O4) except for routine F07BDF which had to be compiled without optimization for the library libnag.so.19.
The libraries libnag.so.19 and libnag-spl.so.19 were also compiled with the
additional flags
The -dalign flag must always be used when compiling an application
which is to be linked with one of the NAG object libraries. When linking a
multi-threaded driver with the library, the
The libnag.a and libnag.so.19 object libraries have been tested using the Basic Linear Algebra Subprograms (BLAS) and linear algebra routines (LAPACK) provided by NAG (see the Chapter Introductions for F06, F07 and F08 in the NAG Fortran Library Manual). The libnag-spl.a and libnag-spl.so.19 object libraries do not contain BLAS/LAPACK entries and were tested using the SPARC-specific BLAS/LAPACK routines in the (optional) Sun Performance Library (v5.0).
For further details, refer to other documentation supplied or contact NAG (see Section 6).

To install all material use the Unix tar utility, e.g.
tar xvf /cdrom/fl19.tar(assuming the CD-ROM has been mounted as /cdrom).
A site may not need to install all four of the object libraries provided in this distribution. After installing all material as described above, you may wish to delete some material if it is not required.
To decide which is the most suitable object library for your site, determine:
After taking the above remarks into consideration, you may decide to delete some of the libraries.
The object libraries (libnag.a, libnag.so.19, etc.) 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. If you decided to install the shareable versions of the libraries, then once the libraries are in place symbolic links should be made to point to the shareable libraries, e.g.
ln -s libnag.so.19 libnag.so ln -s libnag-spl.so.19 libnag-spl.soUnless this is done, the linker, ld, will not be able to find the shareable libraries.
The script nagexample refers to the local directory containing the example programs. The file should be copied to (for example) /usr/local/bin, modified to reflect the local installation, and its 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_fl_un.3 /usr/local/man/man3
For the NAG Fortran Library you will be provided with an uncounted license key for use on a specific machine.
An uncounted license key consists of one FEATURE or INCREMENT line for each product licensed, for example:
FEATURE NAG_FL NAG 19.000 31-jul-2000 0 CBDA2041DC1BC45D2B68 \
"SOLA," 80896b27
This enables an unlimited number of instances of version 19 of the application NAG_FL until the date specified on the system with hostid 80896b27 only. Note that the line is continued by escaping the newline character with '\'.
You will have to inform NAG of the hostid of the system. To obtain the hostid, locate the FLEXlm utility program 'lmutil' in flsol19da/license/bin/sun4_u5, and run it with argument 'lmhostid'.
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.dator 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.
If the user advice refers to more than one compiled NAG library then each should be checked as above. If any externally-provided library of Basic Linear Algebra Subprograms (BLAS) is to be used then the following example programs should also be run:
F06EAF - testing real Level 1 BLAS
F06GAF - testing complex Level 1 BLAS
F06ERF - testing real sparse Level 1 BLAS
F06GRF - testing complex sparse Level 1 BLAS
F06PAF - testing real Level 2 BLAS
F06SAF - testing complex Level 2 BLAS
F06YAF - testing real Level 3 BLAS
F06ZAF - testing complex Level 3 BLAS
Note that the last four example programs take longer to execute than the average example program. The Users' Note may contain extra information needed when running these tests.
The following material should also be made accessible to users:
documentation files:
doc/essint doc/summary doc/news doc/replaced doc/calls doc/called doc/blas_lapack_to_nag doc/nag_to_blas_lapackone or more of the compiled libraries:
libnag.a libnag.so (symbolic link pointing at libnag.so.19) libnag-spl.a libnag-spl.so (symbolic link pointing at libnag-spl.so.19)example program material:
examples/source/??????e.f examples/data/??????e.d examples/results/??????e.r scripts/nagexample
Note that the example material has been adapted, if necessary, from that printed in the NAG Fortran Library Manual, so that programs are suitable for execution with this implementation with no further changes (but see Section 4.5.2 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.
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.
On-line documentation is bundled with this implementation. Please see the Readme file on the distribution medium for further information.
