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 6th June, I've added around 28 megabytes of files
making around 166M of files available.


STATISTICS
~~~~~~~~~~

During June:
  Over 979,054,193 bytes (933MB) transferred [1195MB in May]
  Over 18,000 file accesses                  [26,000 in May]
  Over 2,400 users                           [2,200  in May]

  85.4% FTP 11.3% Gopher 2.1% WWW 1.3% Email <1% Interactive

  [91.1% FTP 7.0% Gopher 1.1% Email <1% Interactive and WWW in May]

  Top 10 files accessed (excluding directory Index files):

The WWW access is quite dominating the top 10 but the old favourites are
still there -- the full index file and the README.


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.


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

JIPS (via 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.


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
~~~~~~~~~~~
WAIS Indexing of entire archive and USENET newsgroups.
Some articles from older occam User Group newsletters.
Enhanced WWW indices and searching.


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.
