Whenever the NAG Fortran SMP 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 7).
This implementation is a compiled, tested, ready-to-use version of the NAG Fortran SMP Library that is considered suitable for operation on the computer systems detailed below:
hardware: IBM RS/6000 Power3 Systems operating system: AIX 5L v5.1 or compatible Fortran compiler: XL Fortran version 7.1.1 or compatible BLAS library: ESSL SMP Library version 3.3
For information about implementations of the NAG Fortran SMP Library for use on other computer systems please contact NAG.
For further details, refer to other documentation supplied or contact NAG (see Section 7).

compiled library: 17.0 MB example program material: 10.0 MB documentation files: 0.1 MB
To install all material, use the Unix tar utility, e.g.
tar xvf /cdrom/fs20.tar(assuming the CD-ROM has been mounted as /cdrom).
The object library (libnagsmp.a) should be moved to a directory, such as /usr/lib, in the default library search path of the linker, if possible, so that linkage is convenient.
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, should be moved a directory in the man search path, e.g.
cd doc mv nag_smp_un.3 /usr/local/man/man3
The following material should also be made accessible to users:
documentation files:
doc/blas_lapack_to_nag doc/nag_to_blas_lapackcompiled library:
libnagsmp.aexample 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 supplied in the NAG Fortran SMP Library documentation, so that programs are suitable for execution with this implementation with no further changes (but see Section 4.4.2 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 documentation. 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.
hardware: IBM RS/6000 Power3 44P Model 270
operating system: AIX 5L v5.1
Fortran compiler: XL Fortran version 7.1.1
BLAS/LAPACK library: ESSL SMP Library version 3.3
compiler options: -q64 -qfixed -qarch=pwr3 -qtune=pwr3 -qsmp=omp -qnosave
-qxlf77=leadzero
The entire NAG Fortan SMP Library, Release 2, was compiled with full optimization (-O3), except for the following routines which had to be compiled with -O2 optimization.

In this implementation calls to the following Basic Linear Algebra Subprograms (BLAS) are implemented by calls to the ESSL library:
