IBM POWER6, 64-bit, AIX, xlf, Double Precision

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 Library for SMP & Multicore. 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 Library for SMP & Multicore that is considered suitable for operation on the computer systems detailed below:

hardware:          IBM POWER6 systems
operating system:  AIX 6.1 and compatible
Fortran compiler:  IBM XLF version and compatible
Vendor library:    IBM ESSL version and compatible
This implementation is not compatible with previous versions of XLF (i.e. XLF 12 and earlier).

The shared library is only recommended for use with the exact compiler version used to create this implementation (IBM XLF version If this is not the default compiler installation on your system, the environment variable LIBPATH must be set to point to the library directory of the IBM XLF version installation. Given this compatibility issue, users are advised to use the static library whenever possible.

2.2. Derivation

This implementation was produced at Rechenzentrum Garching (RZG) of the Max Planck Society and the IPP (by NAG Ltd. staff) on the computing system detailed below:

hardware:          IBM POWER6
operating system:  AIX 6.1
Fortran compiler:  IBM XLF version 
Vendor library:    IBM ESSL version
Compiler options:  -q64 -qarch=pwr6 -qtune=pwr6 -qundef -qfixed -qnolm \
-qnosave -qthreaded -qxlf77=nopersistent:leadzero -qsmp=omp

The library can be used with or without the compiler flag -qextname.

Each routine in the NAG Library for SMP & Multicore, Mark 22, was compiled with the highest level of optimization that enabled the functionality provided by the library to be verified and validated. Most routines in the library were compiled with optimization flags -O3 ; some routines will have been compiled with a lower level of optimization when necessary.

In this implementation:

The library has been tested with ESSL version Please see the IBM web site for further information about ESSL (

3.2. File Sizes

The files require approximately the following disk space:
  Library software:  178 MB
  Library Manual:    316 MB

4. Installation

4.1. Installation of Library Software and Manual

If you have downloaded the Library materials from our web site as a tar gzip file (fsai622dal.tgz), cd to the directory where the file is located and extract the installation materials using the following commands:
gunzip fsai622dal.tgz
tar xvf fsai622dal.tar
This will extract the files, fs22.tar, lic_agr.txt, 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.tgz
to extract the file mk22_doc.tar.

4.1.1. Installation using install script

You can install the materials by executing the Bourne Shell script 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/fsai622dal or /usr/local/NAG/fsai622dal as [INSTALL_DIR]. This convention is also used in the Users' Note (un.html).

The directory [INSTALL_DIR]/scripts contains two 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 libraries to some other location then these scripts must be changed to reflect that fact.

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 static version is usually used by default.

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 the NAG Library for SMP & Multicore is controlled by the Kusari license management system. This release of the NAG Library for SMP & Multicore uses version 2.2 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/aix64/ 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 FSAI622DAL), 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:

FSAI622DA TRIAL 2010/11/12 "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

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.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, 3.3 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 D01AUF, E04UCA and F07ADF. The installation can also be tested using the scripts nagsmp_example and nagsmp_example_shar. (see Users' Note, Section 3.3). 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_fl22 directory contains the Library Manual.

compiled libraries:

interface block 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 3.3 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.

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 A00AAF, or you could call the script nagsmp_example with the arguments a00aaf 1. See Users' Note, Section 3.3. This example prints out details of the implementation, including title and product code, compiler and precision used, mark and maintenance level.
