NAG Parallel Library, Release 3

FDLUX03D9

Linux (Intel) NAGWare f95

Installer's Note



Contents

1. Introduction

This document is essential reading for whoever is responsible for the installation of the NAG Parallel Library implementation specified in the title. The installer will be supplied with a printed copy of this document. Both this (doc/in.html) and the Users' Note (doc/un.html) are supplied on the distribution medium.

Whenever the NAG Parallel Library has been supplied in compiled form, that form is considered to be the standard library file. The use of all supplied software must be in accordance with the terms and conditions of the Software Licence signed by NAG and each site. Any request to use NAG software on a computer other than the one licensed must be referred to NAG (see Section 6).

2. Implementation Provided

2.1. Applicability

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

hardware:         Intel Pentium or compatible PCs
operating system: Linux 2.2.17-14 (RedHat 6.2) or compatible
Fortran compiler: NAGWare f95 Release 4.1 or compatible
MPI:              MPICH version 1.2.0 or compatible

For information about implementations of the NAG Parallel Library for use on other computer systems please contact NAG.

2.2. Derivation

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

hardware:         Intel Pentium i686
operating system: Linux 2.2.17-14 (RedHat 6.2)
Fortran compiler: NAGWare f95 Release 4.1(345)
compiler options: -mismatch_all -dcfuns -W0,-cope_with_scalapack_bug
C compiler:       gcc version egcs-2.91.66
MPI:              MPICH version 1.2.0

The supplied archive library libnagmpi.a includes the Fortran MPI version of the Basic Linear Algebra Communication Subprograms (BLACS v1.1, with patch02 dated 18.8.98). The entire NAG Parallel Library, Release 3, was compiled with optimization (-O4).

This implementation has been tested using the Basic Linear Algebra Subprograms (BLAS) provided by NAG in the archive libnagmpiblas.a.

This implementation has also been tested using MPICH version 1.2.1.

3. Distribution Medium

3.1. Recording Details

The implementation is distributed in tar format on CD-ROM, unless otherwise indicated on the medium and accompanying despatch note.

For further details, refer to other documentation supplied or contact NAG (see Section 6).

3.3. File Sizes

The files require approximately the following disk space:
compiled libraries, libnagmpi.a:     10.3 Mb
                    libnagmpiblas.a:  0.5 Mb
                    libnagfls.a:      0.4 Mb
example program material:             0.9 Mb
documentation files:                  0.1 Mb

4. Library Installation

4.1. Installation

To install all material use the GNU tar utility, e.g.

tar xvf /cdrom/fd03.tar
(assuming the CD-ROM has been mounted as /cdrom).

Links to the object libraries libnagmpi.a, libnagmpiblas.a and libnagfls.a should be placed in a directory, such as /usr/lib, in the default search path of the linker so that linkage is convenient.
The object library libnagmpiblas.a is a subset of the BLAS required by the NAG Parallel Library.

The script nagmpiexample is intended to provide users with a simple means of access to the example material. It will require some minor edits to reflect the local installation and should be placed in a directory, such as /usr/local/bin, which is on users' execution search paths.

4.2. Checking Accessibility

The installation may be tested by using the script nagmpiexample (when logged in as a normal user). The script will copy an example program and its data, compile it, link it with the libraries and run it.

For example, give the command

nagmpiexample f04ebfp
to run the F04EBFP example program.

4.3. Release to Users

The Users' Note (doc/un.html) should be checked and amended as necessary (particularly Sections 2.2 and 4). It can then be made available to users directly, or be absorbed into local access information.

The following material should also be made accessible to users:

other library documentation (see Section 5)

compiled libraries:

libnagmpi.a
libnagmpiblas.a
libnagfls.a
example program material:
examples/source/*e.f
examples/data/*e.d
examples/results/*e.r
scripts/nagmpiexample

Making the supplied example material directly available to users provides them with easily adaptable templates for their own problems.

4.4. Maintenance Level

The maintenance level of the supplied library can be determined by writing a simple program to call A00AAFP, which prints out details of the implementation, including title and product code, precision used, release, maintenance level and the underlying message passing mechanism (MPI in this case).

5. Documentation

Each NAG Parallel Library site is ordinarily provided with a printed copy of the NAG Parallel Library Manual (or Update). If you require additional copies then please contact NAG.

On-line documentation is also provided, in PDF form, with this implementation. Please see the Readme file on the distribution medium for further information.
