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. In particular, users must not have free access to the text of the library routines. Any request to use NAG software on a computer other than the one licensed must be referred to NAG (see Section 6).
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: Fujitsu VPP5000 operating system: UXP/V V20L10 Fortran compiler: Fujitsu UXP/V Fortran V20L20 C compiler: Fujitsu UXP/V C V20L20 MPI: Fujitsu UXP/V MPI-2 V20L20 Other libraries: BLAS/VP V20L20, LAPACK/VP V20L20, ScaLAPACK V20L20 Addressing mode: 64-bit
For information about implementations of the NAG Parallel Library for use on other computer systems please contact NAG.
This implementation was produced at Fujitsu Ltd, Japan on the computing system detailed below:
hardware: Fujitsu VPP5000 operating system: UXP/V V20L10 X01021 PUF (UX28219) Fortran compiler: Fujitsu UXP/V Fortran V20L20 L01091 compiler options: -Oe C compiler: Fujitsu UXP/V C V20L20 L01091 compiler options: –O4 MPI: Fujitsu UXP/V MPI-2 V20L20 L00011 UL59538
The entire NAG NAG Parallel Library, Release 3, was compiled with full optimization (-Oe), except for the following routines, which had to be compiled at lesser optimization levels:
This implementation has been tested using the Basic Linear Algebra Subprograms (BLAS) and the Basic Linear Algebra Communication Subprograms (BLACS) provided by Fujitsu.
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).
The following shows the directory/file organization of the materials as they will be installed.
|-- in.html |-- doc --|-- un.html | |-- libnagmpi.a | |-- include --|-- *.h fdfuj03dm --| | |-- source ---|-- *e.f |-- examples --|-- data -----|-- *e.d | |-- results --|-- *e.r | | |-- [a-z] ----|-- * | | | |-- PBBLAS ---|-- * | | | |-- PBLAS ----|-- * |-- source ----| | |-- BLACS ----|-- * | | | |-- TOOLS ----|-- * | | | |-- support --|-- * | | | |-- support_blas --|-- * | |-- scripts ---|-- *
The files require approximately the following disk space:
compiled libraries, libnagmpi.a: 11.7 Mb example program material: 0.7 Mb documentation files: 0.1 Mb scripts: 0.1 Mb library source code: 8.9 Mb (not needed on disk permanently)
To install all material (including source), use the Unix tar utility, e.g.
tar xvf /cdrom/fd03.tar
(assuming the CD-ROM has been mounted as /cdrom).
The source code should be needed only for reference by whoever is responsible for the installation of the library. It should not be made available to users. The include files are required only if the source code is to be recompiled.
A link to the object library libnagmpi.a should be placed in a directory, such as /usr/lang/lib64, in the default search path of the linker so that linkage is convenient.
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.
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
to run the F04EBFP example program. Almost all the example programs have 4 processes. nagmpiexample should be run using jobexec or the NQS system with 5 virtual processors specified.
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. Users should also have access to the other documentation (see Section 5) and the following software:
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.
The maintenance level of the supplied library can be determined either by inspecting the source of routine A00AAZP or 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).
Each supported NAG Parallel Library site is currently provided with a printed copy of the NAG Parallel Library Manual (or Update). If you require additional copies then please contact NAG.
Online documentation is also provided, in PDF form, with this implementation. Please see the Readme file on the distribution medium for further information.
Queries concerning this document or the implementation generally should be directed initially to your local Advisory Service. If you have difficulty in making contact locally, you can contact NAG directly at one of the addresses given in the Appendix. Users subscribing to the support service are encouraged to contact one of the NAG Response Centres (see below).
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 please quote your NAG site reference and NAG product code (in this case FDFUJ03DM).
The NAG websites are an information service providing items of interest to users and prospective users of NAG products and services. The information is reviewed and updated regularly and includes implementation availability, descriptions of products, downloadable software, product documentation and technical reports.
