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-8R systems Operating System: SUPER-UX 16.1 and compatible Fortran Compiler: FORTRAN90/SX Rev. 340 and compatible
This implementation was produced at NEC Corporation, 1-10, Nisshin-cho, Fuchu, Tokyo, 183-8501, Japan, on the computing system detailed below:
Hardware: NEC SX-8R
Operating System: SUPER-UX 16.1
Fortran compiler: FORTRAN90/SX Version 2.0 for SX-8R Rev.340 2006/06/30
Compiler options: -dw -Pstack -Wf,-P,a,nh,-pvctl,nomsg,-Ni -Cvopt
-Wf,-O,nomsg -Wf,-pvctl,noassume,vwork=stack,vl=max512
The entire NAG Fortran Library, Mark 21, was compiled with full optimization (-Cvopt), except for the following routines, which had to be compiled at lesser optimization levels:

This library has 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 Mark 21 Library Manual, which we will refer to as the Library Manual).
This library has also been tested with the tuned NEC BLAS/LAPACK library MathKeisan/SX 2.0.0.

libnag_nec.a does not contain the NAG version of Basic Linear Algebra Subprograms (BLAS) nor the linear algebra functions (LAPACK). It has been tested with the BLAS/LAPACK provided by the NEC.
If the NEC tuned BLAS/LAPACK are available, then it is recommended that these should be used, together with the library libnag_nec.a; if the NEC tuned BLAS/LAPACK are not available, then libnag_nag.a can be used instead.
The NEC tuned BLAS/LAPACK are available in the NEC product Mathkeisan/SX. This product can be obtained from NEC by visiting http://www.mathkeisan.com/.

./install.shBy default, the materials will be installed in /usr/opt/NAG/ or /usr/local/NAG/ depending on your system. The installer may choose a different location. In this document we refer to the directory /usr/opt/NAG/fln8r21dc or /usr/local/NAG/fln8r21dc as the [INSTALL_DIR].
The directory [INSTALL_DIR] is referenced in the Users' Note (un.html).
The directory [INSTALL_DIR]/scripts contains one or more scripts to show how to use the libraries provided with this implementation. See Users' Note, Example Programs. Subsequent to the installation, if the installer moves the library to some other location then these scripts must be changed to reflect that fact.
To simplify access to the libraries you may wish to create symbolic links in a system location such as /usr/lib pointing at the installed libraries. They would then be in the default search path of the linker during the link phase.
The NAG Fortran Library Interface Blocks define the type and arguments of each user callable NAG Fortran Library routine. These are not essential to calling the NAG Fortran Library from Fortran 90/95 programs. Their purpose is to allow the Fortran 90/95 compiler to check that NAG Fortran Library routines are called correctly.
The interface block files (nag_interface_blocks/*) are supplied in both source form and pre-compiled module form.
The -Ipathname option should then be specified on each f90/f95 invocation (where pathname is [INSTALL_DIR]/nag_interface_blocks) to tell the compiler where to find the modules.
The install.sh script can install the Library Manual in the same location as the NAG Library material or at some other location of the installer's choice.
You may wish to move the Library Manual to the same location as that for other NAG products. You are encouraged to make them readily available to users.
Use the tar utility to extract the materials, e.g.
tar xvf /cdrom/fl21.tar(assuming the CD-ROM has been mounted as /cdrom).
The libraries are provided in static format. You have a choice of libraries; a self contained library which uses NAG supplied BLAS and LAPACK or a library which require the use of vendor supplied BLAS and LAPACK. You may choose to install one or both libraries.
To simplify access to the libraries you may wish to create symbolic links in a system location such as /usr/lib pointing at the installed libraries. Then they would be in the default search path of the linker during the link phase.

The directory [INSTALL_DIR]/scripts contains one or more scripts to show how to use the libraries provided with this implementation. These scripts 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.
To install the Library Manual, use the tar utility, e.g.
tar xvf /cdrom/mk21_doc.tar(assuming the CD-ROM has been mounted as /cdrom).
You may wish to move the Library Manual to the same location as that for other NAG products. You are encouraged to make them readily available to users.
The following material should also be made accessible to users:
documentation files:
The nagdoc_mk21 directory contains the Library Manual. This should be made available to users.
compiled libraries:
libnag_nag.a libnag_nec.ainterface block files:
nag_interface_blocks/*example program material:
examples/source/??????e.f examples/data/??????e.d examples/results/??????e.r scripts/nag_example*
Note that the example material has been adapted, if necessary, from that published in the Library Manual, so that programs are suitable for execution with this implementation with no further changes (but see Section 4.3.1 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 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 can be done by running a few example programs following that advice. The installation can also be tested using the scripts nag_example*.
On-line documentation is bundled with this implementation. Please see Section 4.
