Your attention is drawn to the terms and conditions of the Software Licence regarding the use of NAG software. Any request to use this software other than on the licensed computer must be referred to NAG, as should requests for information about the availability of other implementations.
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 operating system: IRIX 6.5 or compatible Fortran compiler: SGI MIPSpro 7.3.1.2 Fortran 77 or Fortran 90Note, however, that the two routines X04ACF and X04ADF are not compatible with Fortran 90.
This implementation was produced at NAG Ltd., Oxford on the computing system detailed below:
hardware: Silicon Graphics Origin 3400
operating system: IRIX 6.5
Fortran compiler: SGI MIPSpro 7.3.1.2
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 20, was compiled with full optimization (-O3), except for the following routines, which had to be compiled with -O2 optimization:
c06fpst.f d02qfvt.f d06daft.f f02bjxt.f x03aayt.f d02nmxt.f d06cbst.f d52qfvt.f g13fgtt.f
This library has 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). It has also been tested using the set of BLAS and LAPACK routines supplied by Silicon Graphics in the SGI Scientific Computing Software Library (SCSL) version 1.3.0.0.
The software is ordinarily distributed in tar format on CD-ROM.

cd /opt tar xvf /cdrom/fl20.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, license daemons, compiled libraries, interface blocks and examples, e.g.
cd /opt
tar xvf /cdrom/fl20.tar flsg620dal/doc flsg620dal/license \
flsg620dal/lib32/mips4 \
flsg620dal/interface_blocks_lib32 \
flsg620dal/examples flsg620dal/scripts/nagexample
for the MIPS IV / n32 libraries.
It is advisable that the libraries are kept in the installed directory, /opt/flsg620dal/, and appropriate symbolic links `libnag.a', `libnag.so', `libnag_scs.a' and `libnag_scs.so' made to them from appropriate system library directories where the linker (ld) will find them, e.g., for the MIPS IV / n32 libraries.
ln -s /opt/flsg620dal/lib32/mips4/libnag.a /usr/lib32/mips4/libnag.a ln -s /opt/flsg620dal/lib32/mips4/libnag.so /usr/lib32/mips4/libnag.so ln -s /opt/flsg620dal/lib32/mips4/libnag_scs.a /usr/lib32/mips4/libnag_scs.a ln -s /opt/flsg620dal/lib32/mips4/libnag_scs.so /usr/lib32/mips4/libnag_scs.so
For the MIPS III / n32 libraries, an appropriate directory is /usr/lib32/mips3; for the MIPS III and MIPS IV / n64 libraries 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 modified to reflect the local installation, and 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.
In order to enable the software, NAG will issue you with a license key. The license key is a simple text file (usually called license.dat), containing details of the software that will be enabled.
A short term (demonstration or trial) license key contains one or more lines like the following:
FEATURE NAG_FL NAG 20.000 10-apr-2002 0 CBDA2041DC1BC45D2B68 "ANY" DEMOSpecifically, it does not have any lines starting with the word SERVER and is referred to here as an uncounted license key. Longer term uncounted license keys must be locked to a specific computer, i.e. they will enable the software on one computer only. These license keys include the FLEXlm hostid of the computer instead of the word DEMO above.
To apply for a longer term license key, contact one of the NAG Response Centres quoting the product to be licensed and the FLEXlm hostid for the computer. To obtain the FLEXlm hostid, select the appropriate lmutil program from the platform specific directory under the license/bin/ subdirectory, and run it with argument lmhostid e.g.:
license/bin/sgi32_u6/lmutil lmhostidOn systems without an ethernet card, use the arguments lmhostid -long.
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_FILENo other actions are required to install an uncounted license.
Further details about FLEXlm and how it may be configured to suit your local circumstances are included in the FLEXlm End Users Guide supplied in the license/htmlman/flexuser/ subdirectory.
tar xvf /cdrom/pdf.tar(assuming the CD-ROM has been mounted as /cdrom).
You may wish to move the PDF documentation files to the same location as that for other NAG products. You are encouraged to make them readily available to users, but in such a way that they are not generally accessible from outside your site. Further information is contained in the readme file on the distribution medium.
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. In the script, the ABI and ISA must be specified in the variables STD and LD_LIBRARY_PATH.
Since several compiled NAG libraries are included in this implementation, it is advisable that each should be checked. 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: The NAGdoc directory contains the online documentation. This should be made available to users, in addition to the following:
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_scs.a lib[32|64]/mips[3|4]/libnag_scs.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.
On-line documentation is bundled with this implementation. Please see Section 4.2.
