Installer's Note



Contents


1. Introduction

This Installer's Note is essential reading for whoever is responsible for the installation of this implementation of the NAG SMP 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. 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.

2. Implementation Provided

2.1. Applicability

This implementation is a compiled, tested, ready-to-use version of the NAG SMP Library that is considered suitable for operation on the computer systems detailed below:

hardware:          Fujitsu HX600 systems and compatible
operating system:  Linux 2.6.9-67.ELlargesmp (glibc-2.3.4-2.39) and compatible
Fortran compiler:  Fujitsu Fortran Compiler Driver Version 3.0 and compatible
Vendor library:    The thread-parallel version of the Fujitsu Scientific 
                   Subroutine Library "SSL II" (FJSVplang-ssl2-3.0.0-0) and compatible

2.2. Derivation

This implementation was produced at Fujitsu Technical Computing Facility, Paris, France (by NAG Ltd. staff) on the computing system detailed below:

hardware:          Fujitsu HX600
operating system:  Linux 2.6.9-67.ELlargesmp (glibc-2.3.4-2.39)
Fortran compiler:  Fujitsu Fortran Compiler Driver Version 3.0 
Vendor library:    The thread-parallel version of the Fujitsu Scientific 
                   Subroutine Library "SSL II" (FJSVplang-ssl2-3.0.0-0)
Compiler options:  -Kfast -X9 -fw  -Kthreadsafe -KOMP

Most source files were compiled with optimization flags -Kfast -KOMP. It was necessary to compile some code with different optimization flags.

These source files were compiled with optimization flags -O0 -KOMP

f11mehn.f    f11mepn.f    x03aayn.f

These source files were compiled with optimization flags -O3 -KOMP

c02afxn.f    f08pszn.f    g03fazn.f    g05ykfn.f

In this implementation calls to BLAS and LAPACK routines are implemented by calls to the thread-parallel version of the Fujitsu Scientific Subroutine Library "SSL II", except for the routines reported in Users' Note, Routine-specific Information. The library has been tested with SSL II (FJSVplang-ssl2-3.0.0-0).

2.3. Post Release Information

Please check the following URL: Post Release Information for details of any new information related to the applicability or usage of this implementation.

3. Distribution Medium

The software is ordinarily distributed in tar format on CD-ROM.

4. Installation

4.1. Installation of Library Software and Manual

This section provides two ways of installing the software, manual and other material provided.

4.1.1. Installation using install script

You can install the materials from the CD or download directory by executing the Bourne Shell script install in a command window as:
./install.sh
By default, the materials will be installed in /opt/NAG/ or /usr/local/NAG/ depending on your system. The installer may choose a different location. In this document we refer to the directory /opt/NAG/fsfl621da or /usr/local/NAG/fsfl621da as [INSTALL_DIR].

The directory [INSTALL_DIR] is referenced in the Users' Note (un.html).

The directory [INSTALL_DIR]/scripts contains one script to show how to use the library provided with this implementation. See Users' Note, Example Programs. Subsequent to the installation, if the installer moves the library to some other location then this script must be changed to reflect that fact.

To simplify access to the library you may wish to create a symbolic link in a system location such as /usr/lib/sparcv9 pointing at the installed library. The NAG SMP Library would then be in the default search path of the linker during the link phase.

The NAG SMP Library interface blocks define the type and arguments of each user callable NAG SMP Library routine. These are not essential to calling the NAG SMP Library from Fortran 90/95 programs. Their purpose is to allow the Fortran compiler to check that NAG SMP Library routines are called correctly.

The interface block files (nag_interface_blocks/*) are supplied in both source form and pre-compiled module form.

The -Am and -Ipathname options should then be specified on each compiler invocation (where pathname is [INSTALL_DIR]/nag_interface_blocks) to tell the compiler where to find the modules (see Users' Note, Accessing the Library).

The install script can install the Library Manual in the same location as the NAG Library material or at some other location of the installer's choice.

You may wish to move the Library Manual to the same location as that for other NAG products. You are encouraged to make them readily available to users.

4.1.2. Installation without using install script

The library can be installed manually by following the instructions below:

Use the tar utility to extract the materials, e.g.

tar xvf /cdrom/fs21.tar
(assuming the CD-ROM has been mounted as /cdrom).

To simplify access to the library you may wish to create a symbolic link in a system location such as /usr/lib/sparcv9 pointing at the installed library. The NAG SMP Library would then be in the default search path of the linker during the link phase.

The NAG SMP Library interface blocks define the type and arguments of each user callable NAG SMP Library routine. These are not essential to calling the NAG SMP Library from Fortran 90/95 programs. Their purpose is to allow the Fortran compiler to check that NAG SMP Library routines are called correctly.

The interface block files (nag_interface_blocks/*) are supplied in both source form and pre-compiled module form.

The -Am and -Ipathname options should then be specified on each compiler invocation (where pathname is [INSTALL_DIR]/nag_interface_blocks) to tell the compiler where to find the modules (see Users' Note, Accessing the Library).

The directory [INSTALL_DIR]/scripts contains one script to show how to use the library provided with this implementation. This script refers to the local directory containing the example programs. The file should be copied to (for example) /usr/local/bin, modified to reflect the local installation, and its protection set to world execute.

To install the Library Manual, use the tar utility, e.g.

tar xvf /cdrom/mk21_doc.tar
(assuming the CD-ROM has been mounted as /cdrom).

You may wish to move the Library Manual to the same location as that for other NAG products. You are encouraged to make them readily available to users.

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 D01AUF, E04UCA and F07ADF. The installation can also be tested using the script nagsmp_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_mk21 directory contains the Library Manual. This should be made available to users.

compiled libraries:

  libnagsmp.a
interface block files:
  nag_interface_blocks/*
example program material:
  examples/source/??????e.f
  examples/data/??????e.d
  examples/results/??????e.r
  scripts/nagsmp_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 4.3.1 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. Example Programs

The example results distributed were generated at Mark 21, using the software described in Section 2.2. These example results may not be exactly reproducible if the example programs are run in a slightly different environment (for example, a different Fortran compiler, a different compiler library, or a different set of BLAS or LAPACK routines). 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.

The installer should ensure that the advice given to users in Section 3.1 of the Users' Note (un.html) is suitable for the installation. This can be done by running a few example programs following that advice. The installation can also be tested using the script nagsmp_example.

4.3.2. 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, Example Programs . This example prints out details of the implementation, including title and product code, compiler and precision used, mark and maintenance level.
