The information in this section supplements that found in the NAG installation notes and concerns only the NAG Fortran double precision library, release MARK 16. For further details, consult the NAG installation notes for the platform in question.
The NAG library should be installed on CERNVM, the VXCERN cluster and in AFS. It will be automatically copied from AFS into the asis tree, accessed via NFS on those systems that do not have AFS.
In AFS, it should be stored in /afs/cern.ch/asis/packages/licensed/nag-mark16/@sys. On asis, the corresponding tree is /asis/packages/licensed/nag-mark16/@sys.
For management purposes, a separate volume is created for each operating system.

Unix versions of NAGLIB should be delivered with on QIC or DAT tapes. There is a DAT drive on hpcernlib and a QIC drive on zfatal.
Go to the directory where you would like to install the software, e.g. /asis/packages/licensed/nag-mark16/rs_aix32, mount the tape in the drive and load the software by typing tar x.
On some systems, more than one version of NAGLIB exists. For example, on RS6000s and HP/UX, versions both with and without the trailing underscore are provided.
In general, make sure that the file libnag.a

In the above list, 3 links where created locally, the Alpha/OSF shared library was renamed and the RS6000 library rebuilt locally. In fact, the NAG supplied libnag_u.a would have been sufficient.
Test programs can be run in the following manner:
Running the test programs

The VM/CMS version of NAGLIB arrives on 9 track tape. As there are no more units of this type on the CERN central services, the first step is to copy the tape to a 3480 cartridge. This can be done in the tape vault, with the help of the DCS staff.
Having copied the tape, it must now be loaded. This is done using the CMS TAPE command.
Procede as follows:

The installation documentation is supplied in a single file: DOCS DOC. This can be split using the COPYFILE command, e.g. using the following EXEC.
Unpacking the documentation file

One should then run some tests to verify that the installation is ok. As on other systems, we run three tests, A02AAF, G05FFF and X03AAF. These tests can be found in the file EXPT FORTRAN. As was the case with the documentation file, this file can be split using the COPYFILE command, or simply with a text editor. Input data for those tests that require it can be found in the file EXPD DATA.

The remaining two tests can be run in a similar manner, with the exception that G05FFF has no input data. The correct results from these programs can be found in the file EXPR RESULTS. Finally, one should modify or create the GIME NOTICE file, e.g.

NAG Fortran Library - Mark 16
The NAG software has been purchased ONLY for local usage at CERN.
Please contact the CERN Program Library Office for information on
the availability and licensing.
See the file UN DOC * (Users' Note) for supplementary information
regarding this version of the NAG Fortran Library.
---------------------------------------------------------------------------
The CERNLIB exec may also need modification to permit access to the new versions of NAGLIB. Once this has been done, the software can be announced.
VMS versions of NAGLIB are supplied on TK50. This is a problem as there are no TK50 drives on the CNLAVC, nor on VXCERN. For the time being, drives still exist on VXLDB2 node. This will not be the case for Mark 17 at which point a different method of distribution, e.g. DLT, must have been found for VMS systems.
On VMS systems, the NAG provided installation instructions should be followed. It was not possible to read the Fortran source on either AXP or VAX, but the libraries were successfully loaded.
The files were then copied to CERN:[NAG.MARK16 on VXCERN and the CNLAVC.
The tests may then be run as on other systems, e.g.
