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:

hardware:          Intel(R) Mac 64 systems and compatible
operating system:  Mac OS X 10.6 Darwin Kernel Version 10.8 and compatible
C compiler:        GCC Compiler for i686-apple-darwin10
                   Version 4.2 and compatible

2.2. Derivation

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

hardware:         MacPro4.1 - Quad-core Intel(R) Xeon(R) CPU @ 2.26GHz
operating system: Mac OS X 10.6.8 (10K549) Darwin Kernel Version 10.8.0
C compiler:       GCC Compiler for applications running on i686-apple-darwin10
                  Version 4.2.1 (Apple Inc. build 5664)

This implementation was also tested at NAG Ltd., Oxford on the computing systems described below:

hardware:         Intel(R) Core(TM) i5-2415M CPU @ 2.30GHz
operating system: Mac OS X 10.7.4 (11E53) Darwin Kernel Version 11.4.0
C compiler:       GCC Compiler for applications running on i686-apple-darwin11
                  Version 4.2.1 (Based on Apple Inc. build 5658)
hardware:         Intel(R) Core(TM) i5-2415M CPU @ 2.30GHz
operating system: Mac OS X 10.8.1 (12B19) Darwin Kernel Version 12.1.0
C compiler:       GCC Compiler for applications running on i686-apple-darwin11
                  Version 4.2.1 (Based on Apple Inc. build 5658)
Please note this this product does NOT support earlier versions of Mac OS.

The NAG C Library, Mark 23, was compiled with the highest level of optimization that enabled the functionality provided by the library to be verified and validated.

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 23 Library Manual, which we will refer to as the Library Manual).

The library has also been tested with the Apple Computer's vecLib versions 3.6, 3.7 and 3.8.

3.2. File Sizes

The files require approximately the following disk space:

  Library software:  177 MB
  Library Manual:    204 MB

4. Installation

4.1. Installation of Library Software and Manual

If you have downloaded the Library materials from our website, double click on CLMI623DGL.dmg. This will extract the two packages CLMI623DGL.pkg and "NAG Fortran Library Manual, Mark 23.pkg" in addition to the files in.html, un.html and License

4.1.1. Installation Procedure

To install the Library Software, double click on CLMI623DGL.pkg and follow the instructions.

By default, the Library Software will be installed in /opt/NAG/. As the installer, you may wish to choose a different location. In this document we refer to the directory /opt/NAG/clmi623dgl or the directory specified by the installer as [INSTALL_DIR].

The directory [INSTALL_DIR] is referenced 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, 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 install the Library manual, double click on "NAG Fortran Library Manual, Mark 23.pkg".

By default, the Library Manual will be installed in /opt/NAG/ however it can be installed to some other location of the installer's choice. For example you may wish to install the Library Manual in 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 the NAG C Library is controlled by the Kusari license management system. This release of the NAG C Library uses version 2.2-58 of Kusari.

A short term (demonstration or trial) license key contains one or more lines like the following:

  CLMI623DG TRIAL 2011/11/12 "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.

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.

License key request and installation is performed through the Apple Installer when clmi623dgl.pkg is installed. During installation, you will be prompted for a license key. If you do not have a license key, a request form will be generated for you to complete and send to NAG via fax or e-mail.

Once you have obtained one of the above license keys it MUST be installed by running the license installer License By default, the license installer will save the license key in /opt/NAG/nag.key (prepends the file if it exists). The Library will then validate the license at runtime.

If you need to update or change the license key after installation, we recommend that you run the license installer again.

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_cl23 directory contains the Library Manual.

compiled libraries:

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.
