This implementation is a compiled, tested, ready-to-use version of the NAG Library that is considered suitable for operation on the computer systems detailed below:
hardware: Intel x86-32 systems and compatible operating system: Linux 4.11.12-100.fc24.x86_64
(GNU C Library (GNU libc) stable release version 2.23) and compatible [Note: requires libstdc++ from GCC 5.1.0 or later] Fortran compiler: Intel Fortran Compiler
version 19.0.3.199 and compatible C compiler: Intel C Compiler
version 19.0.3.199 and compatible vendor library: Intel MKL version 2019.0.3 and compatible
The NAG AD Library is not included in this implementation.
The definitions and sizes of the C Integer and Pointer types used in this implementation are shown in Section 3.5 of the Users' Note.
This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:
hardware: Intel(R) Xeon(R) E5-2603 v4 operating system: Linux 4.11.12-100.fc24.x86_64The flags listed above were chosen to be conservative in terms of performance optimization to prioritize consistency of numerical results. However key computational kernels in the NAG Library have been compiled and tested with higher levels of optimization.

(Fedora 24 (Twenty Four)) Fortran compiler: Intel Fortran Compiler
version 19.0.3.199 20190206 C compiler: Intel C Compiler
version 19.0.3.199 20190206 vendor library: Intel MKL version 2019.0.3 Fortran compiler options: -O3 -axCORE-AVX2,AVX -no-fma -fp-model precise -fp-speculation=safe -auto -fPIC -threads -fexceptions C compiler options : -O3 -axCORE-AVX2,AVX -no-fma -fp-model precise -fp-speculation=safe -fPIC -m32 -fexceptions

Details of the software are given in the Users' Note (un.html).
Assuming you have downloaded the Library materials from our website as a tar gzip file (nllux27dcl.tgz), cd to the directory where the file is located and extract the installation materials using the following command:
tar xvzf nllux27dcl.tgzThis will extract the files install.sh, nl27.tgz, nag_tsandcs.txt, in.html and un.html.
If you have downloaded the Library Manual as a tar gzip file (mk27_doc.tgz), move the file into the same location as the Library materials. You can then install the materials from the download directory by executing the shell script install.sh in a command window as:
./install.shBy default, the materials will be installed under $HOME/NAG/, or if the directory $HOME does not exist, under /opt/NAG/. However, you may choose a different location. In this document we refer to the directory $HOME/NAG/nllux27dcl or /opt/NAG/nllux27dcl as [INSTALL_DIR]. This convention is also used in the Users' Note.
The install script can install the Library Manual in the
same location as the NAG Library material or at some other location of
your choice.
Alternatively, the Library Manual may be viewed from the NAG website
In order to enable the software, NAG will issue you with a licence key as follows. The licence key is contained in a text file consisting of details of the software that will be enabled. For evaluation purposes a trial licence may be used. Before obtaining a full licence you need to know the Kusari hostid of the system on which you intend to use this product. How to do this is described below.
To request a licence key, run the program khostid located in the license/bin/linux_x86 subdirectory of the software distribution. This utility must be run from a command prompt. Return the information that it displays, together with the product code (in this case NLLUX27DCL), by email to NAG. Alternatively, direct the output from this utility to a file and send both the file and the product code to NAG.
A short term (demonstration or trial) licence key contains one or more lines like the following:
NLLUX27DC TRIAL 2019/11/12 "EMnxidA3oeoj0F1Yvi5ibxPjB7"Specifically, it has a line containing the word TRIAL. Longer term licence keys must be locked to a specific computer, i.e. they will enable the software on one computer only. These licence keys typically include the word NODE or FULL instead of the word TRIAL above and may contain extra fields.
Once you have obtained one of the above licence keys, the easiest way to install it is to store the text in a file,
$HOME/nag.keyor
/opt/NAG/nag.keyor
/usr/local/NAG/nag.keyThe licence software in this implementation automatically looks for these particular files and reads the first one found, so no further action is necessary. Alternatively, store the licence in a file with a name and location of your choice, say,
[INSTALL_DIR]/licence.licThe location of the licence file, if it is not one of the default places listed above, must be made known to the NAG application by setting the environment variable NAG_KUSARI_FILE to the full pathname of the file before the application is invoked.
For example, in the C shell, type:
setenv NAG_KUSARI_FILE [INSTALL_DIR]/licence.licor in the Bourne shell, type:
NAG_KUSARI_FILE=[INSTALL_DIR]/licence.lic export NAG_KUSARI_FILE
Further details about Kusari and how it may be configured to suit your local circumstances (e.g. how to install the licence key on a server) are included in the Kusari Licence Management documentation in the license/doc/ subdirectory of the software distribution.
