This is a response to a message which was broadcast by John Blair-Fish on

in it.

Mark 12 of the NAG Fortran Library has been implemented to run on a single
transputer, with an IBM PC front-end, using the INMOS 3L compiler. This
software is available from NAG Ltd. The implementation was done by Liverpool
University.

Mark 13 of the NAG Fortran Library is currently being implemented, again to run
on a single transputer, using the Meiko Fortran compiler:   
   a) on a Meiko Computing Surface   
   b) on a Meiko PC card 
This implementation is being done by the Cambourne School of Mines. As soon as
this work has been completed and certified, it will be available from
NAG Ltd. 

There are no other implementations of the NAG Fortran Library on transputers
which are authorised by NAG. 

We are aware that some individual users have transferred selected NAG Library
routines to various transputer-based systems, having obtained a copy of
the source-text from their local NAG Site Representative. In such cases
they should always sign a NAG source-text release form, and it should be
understood that the routines are only to be used for bona fide research
purposes.

For the future, NAG are currently working with Liverpool University on the
development of a parallel numerical library for the transputer-based Supernode
machine. The work is being undertaken as part of the EC-funded Esprit 2
project, Supernode 2. This parallel library will cover the same principal areas
of numerical computation as the NAG Fortran Library, but, at least initially,
it is likely to be much less extensive in its coverage and not directly
compatible with the NAG Fortran Library. The library will be callable from
Fortran programs, and is intended to be transportable to other transputer-based
systems. When completed, the library will be marketed by NAG Ltd. Liverpool
University developed a small pilot library of parallel numerical routines under
the Supernode 1 project, and this is available from NA Software Ltd. 

NAG is also planning other collaborative research projects to develop
parallel numerical software for various types of parallel architecture,
including transputer-based systems.
