		 Internet Parallel Computing Archive
		 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
		   Supported by SEL-HPC and COMETT
		 Hosted at HENSA Unix (JISC funded)

		    Admininistrative information

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

This archive contains freely distributable software and documents, in
the High Performance and Parallel Computing subject area with special
interest in the Transputer processor concept and the occam language.

There are currently over 424M of files available.

Please consult the accompanying article for details of new files and
services.

I would like some help: the new files postings are getting rather
large (60K in total) for each month.  Would people prefer to see them
more often, say every 2 weeks or even weekly?

MIRROR SITES
~~~~~~~~~~~~

There are THREE full public mirror sites of the archive with
anonymous ftp access:

AUSTRALIA: <URL:ftp://pcrf.anu.edu.au/HENSA/>
	   WWW access to this will be available soon
FRANCE:	   <URL:ftp://ftp.ibp.fr/pub/parallel/>
	   <URL:ftp://ftp.jussieu.fr/pub/parallel/>
JAPAN:	   <URL:ftp://ftp.center.osaka-u.ac.jp/parallel/hensa/>

See <URL:http://www.hensa.ac.uk/parallel/www/mirror-sites.html> for full
details.


WORK IN PROGRESS
~~~~~~~~~~~~~~~~

* Better search database

* Better keywords for files, using IAFA Templates.

* FORM based customised WWW interface created on-the-fly.


STATISTICS

  Note: The Email system has changed on our machine and statistics
  are not possible due to the terrible logs it produces.

  Due the the disk on the French mirror site crashing, the real total
  is probably 3-400M less i.e. 1.3G.

WHERE IS IT?
~~~~~~~~~~~~
At the HENSA (Higher Education National Software Archive) UNIX
archive.  The HENSA UNIX archive is accessible via the World Wide Web
(WWW), ftp, gopher, email and interactively.  For details, see below.


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

If you want to check what has changed in between USENET postings, look
at the /pub/parallel/Changes file which contains the new files added.

There is also a full text index available of all the files in
/pub/parallel/info/FullIndex.ascii but be warned - it is very large
(over 775K).  Compressed and gzipped versions are in the same
directory.

For those UNIX dweebs, there are output files of ls-lR (1.2M) in
/pub/parallel/info/ls-lR along with compressed and gzipped versions
too.


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

There are several ways to access the files which are described below
- use the WWW, gopher, log in to the archive to browse files and
retrieve them by email or transfer files by FTP over the Internet / JIPS.


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

Connect your WWW browser program (e.g. NCSA Mosaic, Netscape
Navigator, Lynx, ...) 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/">Internet Parallel Computing Archive</A>.


Transferring files by FTP from JIPS/the Internet
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
	site: unix.hensa.ac.uk
	directory: /pub/parallel
        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 from the Root Minnesota Gopher gopher, follow the menu entries:

	Other Gopher and Information Servers
	Europe
	United Kingdom
	HENSA unix (National software archive, University of Kent), (UK)
	Internet Parallel Computing Archive

OR go straight to the gopher server at unix.hensa.ac.uk.

	unix% gopher -p 1/.archive/parallel unix.hensa.ac.uk
OR
	<URL:gopher://unix.hensa.ac.uk/11/.archive/parallel>
	(but why not use the WWW interface?)

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

      ftpmail@unix.hensa.ac.uk

containing the single line

      help

for full instructions.


Logging in from the Internet or SuperJANET
------------------------------------------
	telnet unix.hensa.ac.uk

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.


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.
