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 Itanium 2 (IA64) systems and compatible
operating system: 64-bit Linux 
Fortran compiler: Intel Fortran Itanium Compiler Version 9.1 or compatible
MPI:              MPICH 1.2.7p1 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:         SGI Altix
operating system: Red Hat Linux Advanced Server release 2.1AS (Derry) 
                  with SGI ProPack 2.3 
Fortran compiler: Intel(R) Fortran Itanium(R) Compiler for Itanium(R)-based 
                  applications Version 9.1 Package ID: l_fc_p_9.1.032
compiler options: -fPIC -auto -O4
C compiler:       Intel(R) C Itanium(R) Compiler for Itanium(R)-based 
                  applications Version 9.1 Package ID: l_cc_p_9.1.038
compiler options: -DAdd_ -O
MPI:              MPICH Version 1.2.7p1
BLAS:             Intel(R) Math Kernel Library 8.1 for Linux Package ID: 
                  l_mkl_p_8.1.014

Two archive libraries are supplied, libnagmpi.a and libnagmpi_sup.a.

The supplied archive library libnagmpi.a includes the Fortran MPI version of the Basic Linear Algebra Communication Subprograms (BLACS v1.1, with patch03 dated February 24, 2000). Both libraries were compiled with full optimization (-O4).

This implementation has been tested using the Basic Linear Algebra Subprograms (BLAS) provided in Intel(R) Math Kernel Library 8.1 for Linux. The MKL version 8.1 libraries are supplied as a part of this product (see contents).

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:    10.9 Mb
                    libnagmpi_sup.a  0.7 Mb
example program material:            0.9 Mb
documentation files:                 0.1 Mb
MKL (8.1) for IA64 libraries        84.8 Mb

4. Library Installation

4.1. Installation

To install all material use the Unix 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 and libnagmpi_sup.a may be placed in a directory, such as /usr/lib, 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 installer should ensure that the users' environment is set up so that they can compile, link and execute (with the mpif77 and mpirun commands provided by MPICH) an MPI Fortran program that calls the Intel(R) Math Kernel Library. This is usually accomplished by setting the relevant environmentvariables (PATH and LD_LIBRARY_PATH) to the correct values in a script that gets executed at shell startup time. Alternatively, the installer may use the ldconfig(8) program to configure the run-time dynamic linker so that compiler run-time libraries and MKL libraries are accessible but this may be too inflexible for users who might want to use different versions of these libraries. If one relies on the LD_LIBRARY_PATH environment variable, it is imperative that it is set at shell startup time otherwise mpirun will fail, with a typical message "error while loading shared libraries".

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. Almost all the example programs have 4 processes. nagmpiexample uses mpirun (provided by your MPICH installation) to run the processes.

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
libnagmpi_sup.a
example program material:
examples/source/*e.f
examples/data/*e.d
examples/results/*e.r
scripts/nagmpiexample
MKL libraries supplied by NAG
  mkl_64/*

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

On-line documentation is bundled with this implementation. Please see Section 4.
