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.
This implementation is a compiled, tested, ready-to-use version of the NAG Fortran Library that is considered suitable for operation on the computer systems detailed below:
hardware: IBM POWER 6 systems and compatible operating system: Linux 18.104.22.168 and compatible 64bits Fortran compiler: IBM XL Fortran Compiler, Version 12.1 and compatible
This implementation supports the XL Fortran compile-time option -qextname.
This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:
hardware: IBM POWER 6 operating system: Linux 22.214.171.124.el5 (Red Hat Enterprise Linux 5) 64 bits Fortran compiler: IBM XL Fortran Compiler, Version 12.1
The NAG Fortran Library, Mark 22, was compiled with
the highest level of optimization that enabled the functionality
provided by the library to be verified and validated.
Most files were compiled with compiler flags:
-O3 -q64 -qstrict -qnosave -qzerosize -qarch=pwr5 -qtune=auto
It was necessary to compile some code without full optimization.
These files were compiled with compiler flags -O0 -q64 -qstrict -qnosave -qzerosize -qarch=pwr5 -qtune=auto :
g05ylxn.f90These files were compiled with compiler flags -O2 -q64 -qstrict -qnosave -qzerosize -qarch=pwr5 -qtune=auto :
This library has been tested on the computing system detailed below:
hardware: IBM POWER 5 operating system: Linux 126.96.36.199 (SLES 11) 64 bits Fortran compiler: IBM XL Fortran Compiler, Version 12.1 - March 2009 update
This library has been tested using the Basic Linear Algebra Subprograms (BLAS) and linear algebra routines (LAPACK) provided by NAG (see the Chapter Introductions for F06, F07 and F08 in the NAG Mark 22 Library Manual, which we will refer to as the Library Manual).
The library has been also tested with version 4.4 of the IBM® Engineering Scientific Subroutine Library (ESSL). Please see the IBM web site for further information about ESSL (http://www-03.ibm.com/systems/p/software/essl).

The files require approximately the following disk space:
Library software: 356 MB Library Manual: 316 MB
If you have downloaded the Library materials from our web site as a tar gzip file (flil622dal.tgz), cd to the directory where the file is located and extract the installation materials using the following commands:
gunzip flil622dal.tgz tar xvf flil622dal.tarThis will extract the files install.sh, fl22.tar, in.html and un.html.
If you have downloaded the Library Manual as a tar gzip file (mk22_doc.tgz) run the command
gunzip mk22_doc.tgzto extract the file mk22_doc.tar.
./install.shBy default, the materials will be installed in /opt/NAG/ or /usr/local/NAG/ depending on your system. You may choose a different location. In this document we refer to the directory /opt/NAG/flil622dal or /usr/local/NAG/flil622dal as [INSTALL_DIR]. This convention is also used in the Users' Note (un.html).
The directory [INSTALL_DIR]/scripts contains one or more scripts to show how to use the libraries provided with this implementation. See Users' Note, Example Programs. Subsequent to the installation, if you move the library 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 NAG Fortran Library interface blocks define the type and arguments of each user callable NAG Fortran Library routine. These are not essential to calling the NAG Fortran Library from Fortran programs. Their purpose is to allow the Fortran compiler to check that NAG Fortran Library routines are called correctly.
The interface block files (nag_interface_blocks/*) are supplied in both source form and pre-compiled module form. (The source form is only required if the pre-compiled form is incompatible with the compiler in use.)
The -Ipathname option should then be specified on each compiler invocation (where pathname is [INSTALL_DIR]/nag_interface_blocks/ext or [INSTALL_DIR]/nag_interface_blocks/noext) to tell the compiler where to find the modules (see Users' Note, Interface Blocks).
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.
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/ppclinux64/ 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 FLIL622DAL), by e-mail (or FAX) 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:
FLIL622DA TRIAL 2008/11/12 "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, store the text of it in a file, say
[INSTALL_DIR]/license.lic.The location of the license file 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 are included in the Kusari License Management documentation in the license/doc/ subdirectory of the software distribution.
The following material should also be made accessible to users:
The nagdoc_fl22 directory contains the Library Manual. This should be made available to users.
libnag_nag.a libnag_nag.so libnag_essl.a libnag_essl.sointerface block files:
nag_interface_blocks/*example program material:
examples/source/??????e.f examples/data/??????e.d examples/results/??????e.r scripts/nag_example*
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 3.3 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.
The NAG Response Centres are available for general enquiries from all users and also for technical queries from sites with an annually licensed product or support service.
The Response Centres are open during office hours, but contact is possible by fax, email and phone (answering machine) at all times.
When contacting a Response Centre, it helps us deal with your enquiry quickly if you can quote your NAG site reference and NAG product code (in this case FLIL622DAL).
