Whenever the NAG Fortran 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).
This implementation is a compiled, tested, ready-to-use version of the NAG Fortran Library that is considered suitable for operation on the computer systems detailed below:
hardware: Silicon Graphics MIPS III or MIPS IV machine operating system: IRIX 6.5 or compatible Fortran compiler: SGI MIPSpro 7.3 Fortran 77 or 90
For information about implementations of the NAG Fortran Library for use on other computer systems please contact NAG.
This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:
hardware: Silicon Graphics Origin 2000 (R10000)
operating system: IRIX 6.5
Fortran compiler: SGI MIPSpro 7.3 Fortran 77
compiler options: -n32 -mips3 (for MIPS III ISA / n32 ABI)
-n32 -mips4 (for MIPS IV ISA / n32 ABI)
-64 -mips3 (for MIPS III ISA / n64 ABI)
-64 -mips4 (for MIPS IV ISA / n64 ABI)
The entire NAG Fortran Library, Mark 19, was compiled with level 3 optimization (-O3), except for the following routines, which had to be compiled at lesser optimization levels:
c06fprt.f (-O2) d01anyt.f (-O2) d02nmst.f (-O2) d02nmxt.f (-O2) d05bdyt.f (-O2) e04hbzt.f (-O2) e04kdft.f (-O1) e04lbrt.f (-O2) f01axzt.f (-O2) x03aayt.f (-O2)
The libraries have been tested using the Basic Linear Algebra Subprograms (BLAS) and linear algebra routines (LAPACK) provided by NAG (see the Chapter Introductions for F06, F07 and F08 in the NAG Fortran Library Manual). They have also been tested using the set of BLAS and LAPACK supplied by Silicon Graphics in the CHALLENGEcomplib libraries, complib.sgimath version 3.1 on Origin 2000 (R10000).
For further details, refer to other documentation supplied or contact NAG (see Section 6).

The library directories (lib32/mips3, lib32/mips4, lib64/mips3 and lib64/mips4) each contain the following files:
libnag.a - archive library libnag.so - shareable library libnag_csm.a - archive library requiring complib.sgimath libnag_csm.so - shareable library requiring complib.sgimath
each archive library: 26.5-35.0 Mb each shareable library: 16.2-19.3 Mb interface blocks: 6.0 Mb example program material: 5.0 Mb documentation files: 2.5 Mb licensing materials: 15.7 Mb
To install all material use the Unix tar utility, e.g.
cd /opt tar xvf /cdrom/fl19.tar(assuming the CD-ROM has been mounted as /cdrom).
The installer should decide on which of the eight archive and the eight corresponding shareable libraries should be installed. To install all primary material (to be made available to users), use the Unix tar utility to read documentation, compiled libraries, interface blocks and examples, e.g.
cd /opt
tar xvf /cdrom/fl19.tar flsg619da/doc flsg619da/lib32/mips4 \
flsg619da/interface_blocks_lib32 \
flsg619da/examples flsg619da/scripts/nagexample
for the MIPS IV / n32 libraries.
It is advisable that the libraries are kept in the installed directory, /opt/flsg619da/, and appropriate symbolic links 'libnag.a', 'libnag.so', 'libnag_csm.a' and 'libnag_csm.so' made to them from the appropriate system library directories where the linker (ld) will find them, e.g.
ln -s /opt/flsg619da/lib32/mips4/libnag.a /usr/lib32/mips4/libnag.a ln -s /opt/flsg619da/lib32/mips4/libnag.so /usr/lib32/mips4/libnag.so ln -s /opt/flsg619da/lib32/mips4/libnag_csm.a /usr/lib32/mips4/libnag_csm.a ln -s /opt/flsg619da/lib32/mips4/libnag_csm.so /usr/lib32/mips4/libnag_csm.sofor the MIPS IV / n32 libraries.
For the MIPS III / n32 libraries the appropriate directory is /usr/lib32/mips3; for the MIPS III and MIPS IV / n64 libraries the appropriate directories are /usr/lib64/mips3 and /usr/lib64/mips4 respectively.
The script nagexample refers to the local directory containing the example programs. The file should be copied to (for example) /usr/local/bin, modified to reflect the local installation, and its protection set to world execute.
The man page, which directs users to the HTML form of the Users' Note, is provided as an nroff source file and also as a packed, pre-formatted file for systems without the Documentor's Work Bench software option. The relevant file belongs in section 3 of man. It should be moved a directory in the man search path, e.g.
either
cd doc mv nag_fl_un.3 /usr/local/man/man3or
cd doc mv nag_fl_un.z /usr/local/man/cat3
The NAG Fortran Library Interface Blocks define the type and arguments of each user callable NAG Fortran Library routine. These are not essential to calling the NAG Fortran Library from Fortran 90 programs. Their purpose is to allow the Fortran 90 compiler to check that NAG Fortran Library routines are called correctly.
The interface block files (interface_blocks_lib32/*.mod and interface_blocks_lib64/*.mod) are supplied in pre-compiled module form. They should be moved to a suitable location so that access is convenient, e.g.
mkdir /usr/local/lib/fl77_modules_lib32 mv interface_blocks_lib32/* /usr/local/lib/fl77_modules_lib32 mkdir /usr/local/lib/fl77_modules_lib64 mv interface_blocks_lib64/* /usr/local/lib/fl77_modules_lib64
The -I"pathname" option should then be specified on each f90 invocation (where "pathname" is /usr/local/lib/fl77_modules_lib32 or /usr/local/lib/fl77_modules_lib64) to tell the compiler where to find the modules.
For the NAG Fortran 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_FL NAG 19.000 31-jul-2000 0 CBDA2041DC1BC45D2B68 \
"SG6A," 80896b27
This enables an unlimited number of instances of version 19 of the application NAG_FL 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 flsg619da/license/bin/sgi64_u6 or flsg619da/license/bin/sgi32_u6, 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.dator 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.
The specific library used by the linker depends on the compilation options, if any, specified by the user and on the system processor. On systems such as the Silicon Graphics Power Indigo2, based on a R8000 processor, the default, if the SGI_ABI environment variable has not been set, is 64-bit and MIPS IV. On systems such as the Silicon Graphics Origin 2000, based on a R10000 processor, the default, if the SGI_ABI environment variable has not been set, is high performance 32-bit (-n32) and MIPS IV.
A script, runex, is supplied in the scripts directory, as part of the implementation. The script can be used for testing any of the installed libraries as follows.
In the C shell use the commands:
setenv NAG_OPTIONS '-n32 -mips4' runex c02affIn the Bourne shell the equivalent commands would be:
NAG_OPTIONS='-n32 -mips4' export NAG_OPTIONS runex c02affwhere NAG_OPTIONS contains the compiler ABI and ISA options.
Since several compiled NAG libraries are included in this implementation, it is advisable that each should be checked as above. If any externally provided library of Basic Linear Algebra Subprograms (BLAS) is to be used then the following example programs should also be run:
F06EAF - testing real Level 1 BLAS
F06GAF - testing complex Level 1 BLAS
F06ERF - testing real sparse Level 1 BLAS
F06GRF - testing complex sparse Level 1 BLAS
F06PAF - testing real Level 2 BLAS
F06SAF - testing complex Level 2 BLAS
F06YAF - testing real Level 3 BLAS
F06ZAF - testing complex Level 3 BLAS
Note that the last four example programs take longer to execute than the average example program. The Users' Note may contain extra information needed when running these tests.
The following material should also be made accessible to users:
documentation files:
doc/essint doc/summary doc/news doc/replaced doc/calls doc/called doc/blas_lapack_to_nag doc/nag_to_blas_lapackcompiled libraries:
lib[32|64]/mips[3|4]/libnag.a lib[32|64]/mips[3|4]/libnag.so lib[32|64]/mips[3|4]/libnag_csm.a lib[32|64]/mips[3|4]/libnag_csm.sointerface block files:
interface_blocks_lib[32|64]/*.modexample program material:
examples/source/??????e.f examples/data/??????e.d examples/results/??????e.r scripts/nagexample
Note that the example material has been adapted, if necessary, from that printed in the NAG Fortran Library Manual, so that programs are suitable for execution with this implementation with no further changes (but see Section 4.5.2 for comments about possible differences in results obtained). Making the example material directly available to users provides them with easily adaptable templates for their own problems.
The "example programs" for the routines in the F06 chapter are not typical example programs and they are not in the Library Manual. They are test programs, which are supplied to sites for use in an installation test of the Library. Some of them take much longer to run than other example programs. Routines which are equivalent to BLAS, are tested twice: once when called by their NAG F06 names, and once when called by their BLAS names.
