Installer's Note


1. Introduction

This Installer's Note is essential reading for whoever is responsible for the installation of this implementation of the NAG C Library. It is available together with the Users' Note (un.html) on the distribution medium.

Your attention is drawn to the terms and conditions of the Software License regarding the use of NAG software. Requests for information about the availability of other implementations must be referred to NAG.

2. Implementation Provided

2.1. Applicability

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:

operating system:  Linux 2.6.27 (glibc-2.9) and compatible
C compiler:        Intel(R) C Intel(R) 64, Version 14.0.1 and compatible

The definitions and sizes of the Integer and Pointer types used in this implementation are shown in Section 3.3 of the Users' Note.

2.2. Derivation

This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:

hardware:         Intel Xeon E5405 2.00 GHz

The NAG C Library, Mark 24, was compiled with the highest level of optimization that enabled the functionality provided by the library to be verified and validated (-O3).

This library has been tested using the Basic Linear Algebra Subprograms (BLAS) and Linear Algebra PACKage (LAPACK) routines provided by NAG (see the Chapter Introductions for f07, f08 and f16 in the NAG Mark 24 Library Manual, which we will refer to as the Library Manual).

The library has also been tested with version 11.1.1 of the Intel ® Math Kernel Library for Linux (MKL) which is supplied as a part of this product (see Section 3.1). Please see the Intel website for further information about MKL (

3.2. File Sizes

The files require approximately the following disk space:

  Library software:  1.1G
  Library Manual:    250 MB

4. Installation

4.1. Installation of Library Software and Manual

If you have downloaded the Library materials from our website as a tar gzip file then navigate to the directory where the file is located and extract the installation materials using the following commands:

  gunzip cll6i24dcl.tgz
  tar xvf cll6i24dcl.tar
This will extract the files, cl24.tar, lic_agr.txt, in.html and un.html.

If you have downloaded the Library Manual as a tar gzip file (cl24_doc.tgz) run the command

  gunzip cl24_doc.tgz
to extract the file cl24_doc.tar.

4.1.1. Installation Procedure

You can install the materials from the download directory or CD/DVD by executing the Bourne Shell script install in a command window as:

If you are logged in as root then by default, the materials will be installed in /opt/NAG/ or /usr/local/NAG/ depending on your system. However, you may choose a different location. In this document we refer to the directory /opt/NAG/cll6i24dcl or /usr/local/NAG/cll6i24dcl as [INSTALL_DIR]. This convention is also used in the Users' Note (un.html).

The directory [INSTALL_DIR]/scripts contains several scripts to show how to use the libraries provided with this implementation. See Users' Note, Section 3.2. Subsequent to the installation, if you move this product to some other location then these scripts must be changed to reflect that fact.

Each library is provided in both static and shareable format. You also have a choice of libraries; self-contained libraries which use NAG supplied BLAS and LAPACK or libraries which require the use of vendor supplied BLAS and LAPACK.

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, and be available for execution at run time (in the case of shareable libraries). Note that if both the static and shareable version of a library are placed in a directory then the shareable version is usually used by default.

The include files should be moved to a directory such as /usr/include so that they can be accessed during compilation, e.g.

  mv include/*.h /usr/include

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.

You may wish to move the Library Manual to the same location as that for other NAG products. You are encouraged to make it readily available to users.

4.1.2. License Management

The use of this product is controlled by the Kusari license management system. This release of the Library uses version 2.2-72 of Kusari.

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.

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 CLL6I24DCL), 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:

CLL6I24DC TRIAL 2013/11/12 "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 include the word NODE instead of the word TRIAL above.

Once you have obtained one of the above license keys, the easiest way to install it is to store the text in a file,

The 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,
The 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.lic
or in the Bourne shell, type:

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. See also the Kusari FAQ:

4.2. Release to Users

The Users' Note (doc/un.html) should be checked and amended as necessary (particularly Sections 3.1, 3.2 and 5). Advice on accessing the library (see Users' Note, Section 3.1) can be checked by running a few example programs following that advice; a suitable sample would be d01sjc, f07adc and g05sjc. The installation can also be tested using the scripts nagc_example* (see Users' Note, Section 3.2). The Users' Note (doc/un.html) should then be made available to users directly, or be absorbed into local access information.

The following material should also be made accessible to users:

documentation files:

The nagdoc_cl24 directory contains the Library Manual.

compiled libraries:

  libnagc_nag.a (symbolic link pointing at
  libnagc_mkl.a (symbolic link pointing at
  MKL libraries supplied by NAG
  Intel run-time libraries supplied by NAG
include files:
example program material:

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 3.2 of the Users' Note 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.

4.3. Further Information

4.3.1. Maintenance Level

The maintenance level of the Library can be determined by compiling and executing the example that calls a00aac, or you could call one of the nagc_example scripts with the argument a00aac. See Users' Note, Section 3.2. This example prints out details of the implementation, including title and product code, compiler and precision used, mark and maintenance level.
