This Installer's Note is essential reading for whoever is responsible for the installation of this implementation of the NAG Library for .NET.
Your attention is drawn to the terms and conditions of the Software License Agreement (in file lic_agr.txt) regarding the use of NAG software. Any request to use this software other than on the licensed computer must be referred to NAG, as should requests for information about the availability of other implementations.
The NAG Library for .NET Version 2 is applicable to both Windows 32 and Windows 64 systems (x86 and x64).
hardware: x86 and x86-64 systems and compatible operating system: Microsoft Windows .NET: .Net Framework 4.0 or higher (Visual Studio 2010 or later)
You do not need to have Visual Studio, but the system has been tested with Visual Studio Professional and Visual Studio Express.
Note that the 64 bit F# compiler in Visual Studio 2010 can not reference .Net Assemblies compiled for platfom:x64. This is fixed in later versions of Visual Studio. The 32 bit Library may be used with F# in Visual Studio 2010.
More details may be available on the post release page (see Section 2.2).
Please check the following URL:
for details of any new information related to the applicability or usage of this implementation.
The following shows the folder and file organization of the implementation materials as they will be installed on an x86-64 system.
DTW02 bin32/*.dll bin64/*.dll NagLibrary64.dll Naglibrary64.xml NagLibrary32.dll Naglibrary32.xml NagDotNetExampleApp.exe routines-to-run.xml flcsdnet.cs flcsdnet64.cs NagLibrary.chm ExampleClasses/*.cs ExampleData/*.d ExampleResults/*.r Kusari Licence/*.exe readme.html License-agreement.rtf lic_agr.txt unins000.*
By default these files are installed under
C:\Program Files (x86)\NAG\DTW02.
You must have Administrator privileges to install this software.
Downloaded the Library materials from our website, then run the self-extracting executable to start the installation.
After installation, you should ensure that the software described in Section 3 is present and accessible.
This software is provided with an uninstallation facility via
Control Panel|Programs|Uninstall a Program
Control Panel|Programs and Features|Uninstall or change a program
(depending on which view is displayed).
This product may be installed in silent (unattended) mode by running
from a Command Prompt. With the first version, you see a progress bar on the screen as the installation occurs, whereas with the second, nothing is displayed. The files will be installed to the default location and the PATH environment variable will be modified. The default installation location may be overridden by using the /dir switch, e.g. /dir="C:\my folder". To prevent the environment variables being updated, the /type=noenv option may be used.
The use of this product is controlled by the Kusari license management system.
In order to enable the software, NAG will issue you with a license key. The license key is a simple text file containing details of the software that will be enabled. For evaluation purposes a trial license may be used. To get a trial license contact the NAG Technical Support Service. Before obtaining a full license you need to know the Kusari hostid of the system on which you intend to use this product and how to do this is described below.
The easiest way to request a license key is to use the GUI described in the next section. Once you have a key, the same GUI can be used to install it.
The information below covers the most common requirements. For more complex licensing situations, please contact us.
The recommended way to request a license key is to use the GUI program provided. This will help you to build a standard message requesting either a trial key or a full key which can be pasted into an email to the NAG Technical Support Service. In the case of a full key, the message contains the Kusari hostid.
Once you have your license key, the same GUI can be used to install the key in the registry.
You can execute this GUI via the shortcut Request or Install NAG License Key for DTW3A02DAL found in the Start menu (Start->NAG->NAG Library for .NET Version 2).
To ensure that the license has been installed correctly please run the NAG Library for .NET Example Application (described in Section 7.1 below) and execute an example program.
The 32 bit assembly, NagLibrary32.dll was built using the following options
/target:library /platform:x86 /optimize
The 64 bit assembly, NagLibrary64.dll was built using the following options
/target:library /platform:x64 /optimize
It follows that the 32 bit assembly can be used on both 32 and 64 bit operating systems with the appropriate platform option.
Help is provided as a Windows HTML help file, and online. The online help may also be downloaded as a zip archive for local installation.
The distributed example results were generated using the 32 bit version of the library with the NAG implementation of BLAS and LAPACK. These example results may not be exactly reproducible if the example programs are run in a slightly different environment. The results which are most sensitive to such differences are: eigenvectors (which may differ by a scalar multiple, often −1, but sometimes complex); numbers of iterations and function evaluations and residuals and other "small" quantities of the same order as the machine precision.
A NAG Library for .NET application is also included which can be executed from the Start menu (Start->NAG->NAG Library for .NET Version 2->NAG Library for .NET Version 2 Example Application). This application provides a GUI that enables any subset of example programs to be conveniently executed, and also provides a check on the Licence Installation and Activation.
The NAG Library for .NET is a fully licence managed product. To use the product you will need to obtain a license key. See Section 4.3 above for details.
