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 and the Users' Note 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: IBM SP2 operating system: AIX 4.1.4 Fortran compiler: mpxlf v3.2 additional systems: The AIX bundled C compiler and run-time libraries must be installed if source is to be recompiled N.B. The IBM Parallel Environment and the IBM implementation of MPI MUST be installed. 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 the Maui High Performance Computing Centre on the computing system detailed below: hardware: IBM 9076 SP2 operating system: AIX 4.1.4 Fortran compiler: mpxlf v3.2.5 C compiler: bundled The entire NAG Parallel/MPI Library was compiled with full optimization (-O3). This library has been tested using the Basic Linear Algebra Subprograms (BLAS) and the Basic Linear Algebra Communication Subprograms (BLACS) provided by NAG. 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.

Library Installation 4.1. Installation To install all material use the UNIX tar utility, e.g. tar xvf /cdrom/fd02.tar (assuming the CD-ROM has been mounted as /cdrom). Note: If your machine already has the libraries containing the Parallel BLAS (PBLAS) and the ScaLAPACK tools library then the corresponding NAG versions of these libraries (libnagpblas.a and libnagtools.a) need not be installed. If your machine already has the Basic Linear Algebra Communication Subprograms (BLACS, release from October 1995 with the patches from September 1996), then the corresponding NAG version (libnagmpiblacs.a) need not be installed. In this case the MPI version of the BLACS must be used. The object libraries (libnagmpi.a, libnagmpiz.a, libnagpblas.a, libnagmpiblacs.a, libnagtools.a and libnagfls.a) should be moved to a directory, such as /usr/local/lib, in the default search path of the linker, if possible, so that linkage is convenient. After the object libraries are in place, run ranlib, e.g. ranlib /usr/local/lib/libnagmpi.a ranlib /usr/local/lib/libnagmpiz.a ranlib /usr/local/lib/libnagpblas.a ranlib /usr/local/lib/libnagmpiblacs.a ranlib /usr/local/lib/libnagtools.a ranlib /usr/local/lib/libnagfls.a The man page should be moved to a directory in the man search path, e.g. cd doc mv nag_mpi_un.3 /usr/local/man/man3 4.2. License Management The use of the NAG Parallel Library is controlled by the FLEXlm network license management system (FLEXlm is a registered trademark of Globetrotter Software Inc). This release of the NAG Parallel Library uses version 6.1 of FLEXlm. The remainder of this section describes how a FLEXlm license key should be installed to enable the use of the Library. Further details about FLEXlm and how it may be configured to suit your local circumstances are included in the FLEXlm End User Manual and FAQ supplied in the directory fdib202dm/license/htmlman. For the NAG Parallel Library you will be provided with an uncounted license key for use on a specific machine. An uncounted license key consists of one FEATURE or INCREMENT line for each product licensed, for example: FEATURE NAG_FD NAG 2.000 31-jul-2000 0 \ CBDA2041DC1BC45D2B68 "IB2M" 80896b27 This enables an unlimited number of instances of version 2 of the application NAG_FD until the date specified on the system with hostid 80896b27 only. Note that the line is continued by escaping the newline character with '\'. You will have to inform NAG of the hostid of the system. To obtain the hostid, locate the FLEXlm utility program 'lmutil' in fdib202dm/license/bin/rs6000_u3, and run it with argument 'lmhostid'. Once you have obtained the license key, store the text of it in a file, say /usr/local/lib/nag/license.dat The location of this file must be made known to the NAG application by setting the environment variable LM_LICENSE_FILE to the full pathname of the file before the application is invoked. For example, in the C-shell, type: setenv LM_LICENSE_FILE /usr/local/lib/nag/license.dat or in the Bourne shell, type: LM_LICENSE_FILE=/usr/local/lib/nag/license.dat export LM_LICENSE_FILE No other actions are required to install an uncounted license. 4.3. Checking Accessibility The installation may be tested by using the `runex' script (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. Environment variables contained in the file `langopts' must be modified to reflect the local setup of your machine. For example, give the command runex f04ebfp to run the F04EBFP example program. This will place the results in the subdirectory examples/newresults. The `runex' script uses `poe', the parallel execution command provided by the parallel environment for the IBM SP2. The command uses the flags `-rmpool' to set the pool from which nodes will be selected to run the job. A value of `0' is given for the pool number, if this is not appropriate the value should be changed. Default values are assumed for all other Parallel Operating Environment variables. The installer should then ensure that the advice given to users in the Users' Note (in the section concerning accessibility) is suitable. The Users' Note is provided in man page form in doc/nag_mpi_un.3, but you may have moved this to /usr/local/man/man3. Note: Some example programs in D01 Chapter of the Library may produce different results by varying the number of nodes. The parallel algorithms used in D01ATFP, D01AUFP and D01AXFP (routines for evaluation of singular one-dimensional integrals) use a non-deterministic master/slave paradigm. For this reason, you may find that the associated example programs may produce different `error estimates' and `number of function evaluations'. This should not be treated as a problem with the Library as long as the `computed result' is the same and the computed `error estimate' is of the same order in different runs of these example programs. 4.4. Release to Users The supplied Users' Note should be checked and amended as necessary (particularly the section concerning accessibility). The Users' Note is provided in man page form in nag_mpi_un.3. The following material should be made accessible to users: compiled libraries: libnagmpi.a libnagmpiz.a libnagpblas.a (or an equivalent PBLAS implementation) libnagmpiblacs.a (or an equivalent MPI-based BLACS implementation) libnagtools.a (or an equivalent ScaLAPACK tools implementation) libnagfls.a example program material: examples/source/*e.f examples/data/*e.d examples/results/*e.r scripts/runex man pages: doc/nag_mpi_un.3 documentation: doc/contents.ascii doc/news.ps doc/future.ps doc/reserved.ascii doc/essint.ps doc/tutorial/tutorial.ps tutorial example program material: doc/tutorial/*.f doc/tutorial/*.dat Making the supplied example material directly available to users provides them with easily adaptable templates for their own problems. 5.
