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.

Since the last posting on 4th August, 23 megabytes of files have
been added making around 209M of files available.

Well!  The new HTML link pages have pushed everything else a long
way down the list. The first binary file is at #18 and that is the
Networks, Routers and Transputers book, first part of chapter 10.


WHERE IS IT?
~~~~~~~~~~~
At the HENSA/Unix (Higher Education National Software Archive)
archive, funded by the JISC.  The HENSA/Unix archive is
accessible via an interactive browsing facility, called fbr as
well as email, DARPA ftp, gopher and NI-FTP (Blue Book) services.

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 the /parallel/Changes 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 330K).  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.

Logging in:
~~~~~~~~~~~
Via the Internet or UK's SuperJANET / JIPS:
	telnet unix.hensa.ac.uk	(or 129.12.43.16)

JANET X.25 network:
	call uk.ac.hensa.unix (or 000049200900 if you do not have NRS)

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.


Transferring files by FTP
~~~~~~~~~~~~~~~~~~~~~~~~
DARPA 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'.


The NI-FTP (Blue Book) request over JANET
        <ARCHIVE>path-of-file  from uk.ac.hensa.unix
        Username: guest
        Password: <your email address>

The program to do an NI-FTP transfer varies from site to site but
is usually called hhcp or fcp.  Ask your local experts for
information.


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.


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


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.


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

If you have Mosaic, Lynx or another World-Wide-Web client, you can
connect to the parallel archive's WWW server via the following URL:

	http://unix.hensa.ac.uk/parallel/index.html

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

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


COMING SOON
~~~~~~~~~~~
Some articles from older occam User Group newsletters.
Pictures of T9000s and real hardware.


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.
