Installer's Note



Contents


1. Introduction

This document provides implementation-specific information relating to the installation of the NAG Library specified in the title.

By installing this software you agree to NAG's Terms and Conditions. Please note that these Terms and Conditions are subject to change without notice. The NAG Software Licence Terms and Conditions and details of revisions are available from https://www.nag.co.uk/content/nag-terms-conditions.

2. Implementation Provided

2.1. Applicability

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 (R) Mac 64 systems and compatible
operating system:  macOS 10.13 Darwin Kernel Version 17.0.0 and compatible
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.

2.2. Derivation and Additional Test Platforms

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

hardware:          Intel(R) Core(TM) i5-4278U  
operating system:  macOS 10.13 Darwin Kernel Version 17.0.0
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 (with -i8 for 64-bit integers) C compiler options : -O3 -axCORE-AVX2,AVX -no-fma -fp-model precise -fp-speculation=safe -fno-inline -fPIC -m64 -fexceptions
This implementation includes libraries (and associated files) for use with both 32-bit integers (denoted by lp64) and 64-bit integers (denoted by ilp64). The 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.

For details of any other systems on which this implementation has been tested, please see the Supplementary Information page on our website.

Please see the Intel website for further information about MKL (https://software.intel.com/intel-mkl).

4. Installation

4.1. Installation of Library Software and Manual

If you have downloaded the Library materials, double click on nlmi627dbl.dmg to mount the disk image. You should see the files install.command, nl27.tgz, nag_tsandcs.txt, in.html, un.html and mk27_doc.tgz.

To install the Library software, double click on install.command and follow the instructions. By 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/nlmi627dbl or /opt/NAG/nlmi627dbl 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 (https://www.nag.co.uk/numeric/nl/nagdoc_27/).

4.1.1. Silent Installation

From a command line, it is also possible to run install.command in unattended or silent modes. The installer takes command line switches for this purpose:

4.1.2. Licence Management

The use of this product is controlled by the Kusari licence management system. This release of the Library uses version 2.2-88 of Kusari.

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/macx64 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 NLMI627DBL), 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:

  NLMI627DB 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.key
or
  /opt/NAG/nag.key
The 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.lic
The 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.lic
or 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. See also the Kusari FAQ: https://www.nag.co.uk/content/kusari-frequently-asked-questions.

4.2. Further Information

4.2.1. Checking the Installation

Access to the Library materials can be checked by running a few example programs following the advice given in the Users' Note, Section 3.1; a suitable sample would be d01auf, e04uca, f07adf, d01sjc, f07adc and g05sjc. The installation can also be tested using the script nag_example (see Users' Note, Section 3.3).
