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: Cray T3E systems operating system: UNICOS/mk 2.0.3 or later Fortran compiler: Cray CF90 v3.0.2.3 or later C compiler: cc v3.0.2.1 and run-time libraries must be installed if source is to be recompiled MPI: MPT (Cray implementation of MPI) version 1.2.1.0 If a different version of MPT or a different implementation of MPI is installed, the supplied BLACS library (libnagmpiblacs.a) may have to be rebuilt with different options set in the file Bmake.inc. 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 by NAG Ltd. staff logged in remotely to Cray Research in Eagan, MN on the computing system detailed below: hardware: Cray T3E operating system: UNICOS/mk 2.0.3 Fortran compiler: Cray CF90 v3.0.2.3 C compiler: cc v3.0.2.1 MPI: MPT (Cray implementation of MPI) version 1.2.1.0 The entire NAG Parallel Library, Release 2, was compiled with the following switches for the Fortran source code: -dp disables double precision arithmetic -X m directs the compiler to generate a malleable object file, it allows you to change the number of processors used each time the executable file is run -O 2,aggress specifies the level 2 of optimization and raises the limits for internal tables, which increases opportunities for optimization The C source code was compiled with the analogous switches. More detailed information on the meaning of the different switches can be found in the CF90 compiler documentation. Some routines in the library have been compiled using the level 0 of optimization, -O 0: d01axfpt.f d01axtpt.f d01axvpt.f d01axwpt.f d01axypt.f d01axzpt.f e04jbfpt.f e04jbwpt.f e04jbxpt.f e04jbypt.f e04jbzpt.f f11bbfpt.f f11bbupt.f f11bbvpt.f f11bbwpt.f f11bbxpt.f f11bbypt.f f11bbzpt.f This library has been tested using the Basic Linear Algebra Subprograms (BLAS) and the Basic Linear Algebra Communication Subprograms (BLACS) provided by NAG. Version 1.1 of the BLACS was used in this implementation. 3. Distribution Medium 3.1. Recording Details The implementation is distributed in tar format on 4mm magnetic tape cartridges, unless otherwise indicated on the medium and accompanying despatch note. For further details, refer to other documentation supplied or contact NAG (see Section 6). 3.2.

File Sizes The files require approximately the following disk space: compiled libraries, libnagmpi.a: 4795 kb libnagmpiz.a: 369 kb libnagpblas.a: 1706 kb libnagmpiblacs.a: 1203 kb libnagtools.a: 893 kb libnagfls.a: 1584 kb example program material: 253 kb documentation files: 831 kb scripts: 51 kb libraries source code: 7122 kb support routines source code: 802 kb (source code not needed on disk permanently) 4. Library Installation 4.1. Installation To install all material (including source) use the UNIX tar utility, e.g. tar xvf /dev/rmt0 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, Version 1.1), 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. 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 The libraries and support routines source code should be needed only for updating to a later maintenance level (see Section 4.4) or for reference by the NAG Site Contact. They should not be made available to users. 4.2. 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. 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 these routines 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. 4.3. Release to Users The supplied Users' Note should be checked and amended as necessary (particularly the section "Accessing the Library"). 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 libnagmpiblacs.a libnagtools.a 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. 4.4. Maintenance 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 name and implementation code, precision used, Release, maintenance level and the underlying message passing mechanism (MPI in this case). From time to time, NAG may issue a software maintenance bulletin which will advise on the steps necessary to move to a later level of maintenance. The primary purpose of this bulletin is to inform sites about known errors in the library. Details of corrections are supplied in case the errors are causing serious inconvenience. Contractually a site is not obliged to apply the corrections, which will be incorporated in the next version of the library supplied by NAG, but may choose to do so if it wishes. In the latter case it is important that the source and compiled version of A00AAZP are modified to reflect any such change of Release or maintenance level. Instructions will be given in the bulletins. NAG expects a site to inform its users about the errors described in the bulletin whichever course of action it chooses to adopt. To update a compiled library the installer should compile the modified source, and replace the older versions of these objects in the supplied library with the new. This can be done using the UNIX ar utility, e.g. ar ruvl /usr/local/lib/libnagmpi.a *.o 5. Additional Services from NAG (a) Documentation Each NAG Parallel Library site is provided with a printed copy of the NAG Parallel Library Manual. Additional manuals are available at prices published in the NAG documentation order form. The NAG Parallel Library is also supported by a Hypertext system at extra cost which allows the user to browse through the Library documentation. Users will be advised of the availability of this system for different platforms as they become available. If you require further information please contact NAG. 6. Support from NAG (a) Contact with NAG 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 write to NAG directly, at one of the supplied addresses.
