Your attention is drawn to the terms and conditions of the Software Licence 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 the NAG Fortran Library that is considered suitable for operation on the computer systems detailed below:
hardware: NEC SX-5 and SX-6 Series operating system: SUPER-UX 12.1 or compatible Fortran compiler: f90/SX Rev. 253 or above or compatible
This implementation was produced at NEC Solutions America, Inc., Houston on the computing system detailed below:
hardware: NEC SX-5/8A operating system: SUPER-UX 12.1 Fortran compiler: f90/SX Rev.253 compiler options: -Cvopt -float0 -P stack -Wf,-pvctl,noassume,vwork=stackThe entire NAG Fortran Library, Mark 20, was compiled with full optimization, except for the following routines, which had to be compiled at lesser optimization levels:
c02afwt.f (-Cvsafe) f07mrft.f (-Cvsafe) g03fazt.f (-Cvsafe) c02agyt.f (-Cvsafe) f07mwft.f (-Cdebug) g05lazt.f (-Cdebug) f06bcft.f (-Cvsafe) f08asut.f (-Cvsafe) g05lezt.f (-Cvsafe)
The library libnag.a was 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 library libnag_noblas.a does not use the NAG BLAS and was tested using the NAG LAPACK routines and the NEC tuned BLAS library (libblas.a).

To install all material use the Unix tar utility, e.g.
tar xvf /cdrom/fl20.tar(assuming the CD-ROM has been mounted as /cdrom).
If NEC tuned BLAS are available then it is recommended that these should be used, together with the library libnag_noblas.a; if NEC tuned BLAS are not available then libnag.a can be installed instead.
NEC tuned BLAS are available in the NEC product Mathkeisan/SX. This product can be obtained from NEC by sending an email to technical@atcc.necsys.com.
The appropriate object library (libnag.a or libnag_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.
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 modified to reflect the local installation, and moved to a directory in the man search path, e.g.
cd doc mv nag_fl_un.3 /usr/share/man/man3
The interface block files (interface_blocks/*.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/lib/fl77_modules mv interface_blocks/* /usr/lib/fl77_modulesThe
Alternatively, the files may be moved to the same directory as the pre-defined modules supplied with the compiler
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. Further information is contained in the readme file on the distribution medium.
The following material should also be made accessible to users:

The NAGdoc directory contains the online documentation. This should be made available to users, in addition to the following:

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.
Online documentation is bundled with this implementation. Please see Section 4.2.
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 FLNE520DB).
