This is the administrative information article for the Parallel Computing
Archive at HENSA Unix.  Please consult the accompanying article for details
of the new files and areas.

The archive is at unix.hensa.ac.uk in /parallel.  It contains freely
distributable software and documents, in the High Performance and Parallel
Computing subject area with special interest in the Transputer processor
and occam language.

There are currently 236M of files available.

  I think the number of unique users is going down since more people are
  using anonymous WWW access rather than ftp or email, which ask for your
  email address.

Not much change at the top this month or significant new entries apart from
the few jobs entries.


WHERE IS IT?
~~~~~~~~~~~
At the HENSA Unix (Higher Education National Software Archive) archive,
funded by the JISC.  The HENSA Unix archive is accessible via the WWW, ftp,
gopher as well as an interactive browsing facility called fbr.

The parallel archive is provided with help and funding from SEL-HPC (London
and South East centre for High Performance Computing) project and the EU
COMETT project supporting occam and Transputer training.



HOW DO I FIND WHAT I WANT?
~~~~~~~~~~~~~~~~~~~~~~~~~~
The files are all located in /parallel and each directory contains a short
Index file of the contents.

If you want to check what has changed in between these postings, look at
/parallel/Changes or <URL:http:/www.hensa.ac.uk/parallel/www/changes.html>
file which contains the new files added.  Files older than that are in
/parallel/info/Changes, indexed by year/month.

There is also a full text index available of all the files in
/parallel/info/FullIndex.ascii but be warned - it is very large (over
530K).  Compressed and gzipped versions are in the same directory.

For those UNIX dweebs, there are output files of ls-lR in
/parallel/info/ls-lR along with compressed and gzipped versions too.

In addition, there are several WAIS indices of the archive, which can be
accessed from the WWW home page, see below.


HOW DO I CONTACT IT?
~~~~~~~~~~~~~~~~~~~~

There are several ways to access the files which are described below - log
in to the archive to browse files and retrieve them by email; transfer
files by DARPA FTP over JIPS or use Blue Book NI-FTP.

WWW Access
~~~~~~~~~~

If you have NCSA Mosaic, Netscape Mosaic, Lynx or another World-Wide-Web
browser, you can connect to the WWW server via:

	<URL:http://www.hensa.ac.uk/parallel/>

OR if you want reference me in your WWW tree, please use the following bit
of HTML:

<A HREF="http://www.hensa.ac.uk/parallel/">Parallel Computing Archive</A>.


Transferring files by FTP from JIPS/the Internet
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

	site: unix.hensa.ac.uk	(or 129.12.43.16 on SuperJANET)
        login: anonymous
        password: <your email address>

Use the 'get' command to transfer a file from the remote machine to the
local one.  When transferring a binary file it is important to give the
command 'binary' before initiating the transfer.  For more details of the
'ftp' command, see the manual page by typing 'man ftp'.


Browsing and transferring by gopher
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Starting at the Root Minnesota Gopher gopher, select the following entries:

	8.  Other Gopher and Information Servers/

	5.  Europe/

	45. United Kingdom/

	22. HENSA unix (National software archive, University of Kent), (UK)/

	7.  Parallel Archive/

OR add the following to your .gopherrc

	Name=Parallel Archive
	Type=1
	Port=70
	Path=1/.archive/parallel
	Host=nutmeg.ukc.ac.uk.

OR Use <URL:gopher://unix.hensa.ac.uk/11/.archive/parallel>
   [But if you can use this, the WWW interface is much better]

Then browse the archive.  [The numbers are very likely to change] The short
descriptions are abbreviated to fit on an 80 column display but the long
ones can always be found under 'General Information.' (the Index files).
Updates to the gopher tree follow a little behind the regular updates.


Transferring files by Email
~~~~~~~~~~~~~~~~~~~~~~~~~~
To obtain a specific file email a message to

      archive@unix.hensa.ac.uk

containing the single line

      send path-of-file

or 'help' for more information. Getting /parallel/README, or
/parallel/FullIndex.ascii would be a good start.


Logging in from the Internet or SuperJANET
------------------------------------------

	telnet unix.hensa.ac.uk	(or 129.12.43.16)

Once connected, use the login name 'archive' and your email address to
enter. You will then be placed inside the fbr restricted shell. Use the
help command for up to date details of what commands are available.


COMING SOON
~~~~~~~~~~~
WWW occam and transputer teaching materials.



DONATIONS
~~~~~~~~~
Donations are very welcome.  We do not allow uploading of files directly
but if you have something you want to donate, please contact me.
