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: all NEC SX-5 systems operating system: SUPER-UX 11.1 or greater. Fortran compiler: F90/SX Rev 231
For information about implementations of NAG fl90 for use on other computer systems please contact NAG.
This implementation was produced at NEC Systems Inc, The Woodlands (Texas) on the computing system detailed below:
hardware: SX-5/4 operating system: SUPER-UX 11.1 Fortran compiler: F90/SX Rev 231 compiler options: -P stack -Cvopt -Wf,-pvctl,noassume,vwork=stack
The entire NAG fl90 library, Release 4, was compiled with default optimization (-Cvopt), except for the following underlying procedures, which had to be compiled unoptimized (-Cvsafe):
c06fpf_9d c06fqf_9d c06rqf_9d c06rpf_9d f07bax_9d f07uff_9d f04bff_9d c02agy_7d f02tef_9d g13ezf_9d g13ebf_9d
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 procedures while libnagfl90_noblas.a does not contain the NAG version of the BLAS procedures and MUST be used with the vendor tuned BLAS contained in the NEC Mathkeisan product.
The following shows the directory/file organization of the PDF documentation materials as they will be installed.

compiled library: 27.0 Mb compiled library (without NAG BLAS): 26.5 Mb module information files: 16.0 Mb example program material: 6.0 Mb library documentation files: 0.1 Mb PDF documentation files: 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).
Two object libraries (libnagfl90.a and libnagfl90_noblas.a) are provided to enable usage on all NEC SX-5 systems; however, only one of them should be made available at each site. The NEC Mathkeisan product contains components that improve the run-time performance of NAG Library procedures. Consequently if this is licensed then libnagfl90_noblas.a should be made available; otherwise libnagfl90.a should be made available. To make the appropriate library available it 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.
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_modulesThe -I"pathname" 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.
Alternatively, the files may be moved to the same directory as the pre-defined modules supplied with the compiler.
The script nagexample refers to the local directory containing the example programs. The script must be modified to reflect the file locations in the local installation. The script also assumes that libnagfl90.a is being used; if libnagfl90_noblas.a is actually made available the script should be modified, as indicated in comments, to reflect this. The file should then be copied to (for example) /usr/local/bin 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_fn_un.3 /usr/share/man/C
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 examples results given in the directory results are those obtained using libnagfl90.a. Using libnagfl90_noblas.a and the NEC tuned BLAS may produce slightly different results.
The following material should also be made accessible to users:
libnagfl90.a or libnagfl90_noblas.amodules information files:
nag_mod_dir/*.modexample program material:
examples/source/*.f90 examples/data/*.dat examples/results/*.r scripts/nagexamplepdf 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.
Online documentation is provided, in PDF form, with this implementation. Please see the Readme file on the distribution medium for further information.
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 (in this case FNNE504DB).
The NAG websites are an information service providing items of interest to users and prospective users of NAG products and services.
