Your attention is drawn to the terms and conditions of the Software License Agreement (in file lic_agr.txt, see Section 3.1) regarding the use of NAG software. Requests for information about the availability of other implementations must be referred to NAG.
This implementation is a compiled, tested, ready-to-use version of the NAG C Library that is considered suitable for operation on the computer systems detailed below:
hardware: x86_64 systems operating system: Linux 2.6.32-696.6.3.el6.x86_64This implementation is supplied with a custom version of MKL and the relevant NAG C library is only intended to be used with this specific MKL library.
(GNU C Library stable release version 2.12) and compatible C compiler: Intel C Compiler
version 184.108.40.206 and compatible vendor library: Intel MKL version 2017.0.3 (the provided custom version only).
The definitions and sizes of the Integer and Pointer types used in this implementation are shown in Section 3.3 of the Users' Note.
This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:
hardware: Intel(R) Core(TM) i7-6800K operating system: Linux 2.6.32-696.6.3.el6.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.
with GNU C Library stable release version 2.12
(CentOS release 6.9 (Final)) C compiler: Intel C Compiler
version 220.127.116.11 20170411 OpenMP runtime: None. vendor library: Intel MKL version 2017.0.3 compiler options: -O3 -axCORE-AVX2,AVX,SSE2 -no-fma -fp-model precise -fp-speculation=safe -fPIC -m64 -fexceptions

The following shows the directory and file organization of the Library Manual materials after installation.
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 (cll6i261vl.tgz), cd to the directory where the file is located and extract the installation materials using the following command:
tar xvzf cll6i261vl.tgzThis will extract the files install.sh, cl26.tgz, lic_agr.txt, in.html and un.html.
If you have downloaded the Library Manual as a tar gzip file (cl26-1_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/cll6i261vl or /opt/NAG/cll6i261vl 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
Alternatively, the Library Manual may be viewed from the NAG website
In order to enable the software, NAG will issue you with a license key. The license key is contained in a text file consisting of details of the software that will be enabled. For evaluation purposes a trial license may be used. Before obtaining a full license 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 license key, run the program khostid located in the license/bin/linux_x64 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 CLL6I261VL), 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) license key contains one or more lines like the following:
CLL6I261V TRIAL 2017/11/12 "EMnxidA3oeoj0F1Yvi5ibxPjB7"Specifically, it has a line containing the word TRIAL. Longer term license keys must be locked to a specific computer, i.e. they will enable the software on one computer only. These license 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 license keys, the easiest way to install it is to store the text in a file,
/usr/local/NAG/nag.keyThe license software in this implementation automatically looks for these particular files and reads the first one found, so no other action is necessary. Alternatively, store the license in a file with a name and location of your choice, say,
[INSTALL_DIR]/license.licThe location of the license 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]/license.licor in the Bourne shell, type:
NAG_KUSARI_FILE=[INSTALL_DIR]/license.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 license key on a server) are included in the Kusari License Management documentation in the license/doc/ subdirectory of the software distribution.
