15:00 - 15:15  Status of the CERN Magnetic Tape Robot Acquisition
               Speaker - H.Renshall/CERN
               Abstract - In autumn 1995 CN division proposed a
               modernisation plan for the central tape services
               including migration to high capacity tapes and
               automation of all active data. After intensive
               studies the project has just gone out to tender
               on a short list of four different tape drives and
               robotics with delivery for early 1997. The studies
               leading to these selections will be reviewed.

               experiment at DESY to provide transparent
               (file system-like) and efficient access to a

               labs and institutes. Useful progress was made so I
               would like to continue the discussion with the added
               input of our DESY and Italian colleagues.

        THURSDAY Morning - Clusters, Farms, Large Systems

09:30 - 10:00  DANTE : Aleph cluster in Italy
               Speaker - Maurizio Davini/INFN Pisa
               Abstract - The Aleph "DANTE" is a cluster of
               7 HP 735 machines running HPUX 9.05. It is used
               for montecarlo production and data analysis.
               It is configured in a CERN-like way (AFS, nqs/AFS,
               Hepix Scripts) like hpplus. The most interesting
               part is the data storage. It consists of
               an HP Magneto-Optic Changer (88 plates), an
               ACL 4/52 DLT Library (52 DLT 4000s) and HP
               software OpenView Omnistorage that provides
               HSM migration

               Abstract - A MEIKO CS-2 has been installed at
               CERN for over two years now. After an overview
               of the system, which is currently supported by
               Quadrics Supercomputers World Ltd (QSW), a
               subsiduary of Alenia Spazia, the various parallel
               applications will be described. A brief review of
               CPU performance (and price) trends will be followed
               by some thoughts on the future of computing in High
               Energy Physics.

               relatively short period of time one of the Central
               systems with the largest history, CERNVM. The
               presentation will address the key targeted areas
               and the marketing and publicity guidelines which
               were applied to bring this transition to its

               Speaker - Claudia Bondila/CERN
               Abstract - We are developing an "interactive
               benchmark". This benchmark will reproduce a
               typical CERN interactive load and will be used to
               help determine system configurations and to compare
               different hardware platforms. In the talk I will
               describe the procedure we use to categorise users,
               the load simulation programs and show some results.

               can acces the ASIS software from their central
               services in the same way as at CERN and to
               describe the new procedure for a remote site to
               mirror the ASIS contents in an efficient and
               controllable manner. This new piece of software
               will be available in the next months.

11:00 - 12:00  A scalable mail service for mobility era -
               LAL experience with IMAP and IMSP/ACAP
               Speaker - Michel Jouvin/LAL
               Abstract - LAL faces the problem of user
               mobility (geographically or desktop platform).
               One year ago, we began to setup a new mail
               service to deal with the user requirements for
               a mail environment accessible from anywhere
               they are. We chose emerging technologies IMAP
               and IMSP. After a presention of the services
               offered by these protocols, this talk will
               present our experience and our choices for
               servers and clients.

12:00 - 12:30  X11 problems: how the HEPiX X11 scripts can help you

               Abstract - I will present the various problems
               that we've seen while deploying X at CERN and how
               the HEPiX X11 scripts help us. I will also present
               my experiences installing the HEPiX X11 scripts
               outside CERN.

12:30 - 14:00  Lunch

        FRIDAY Afternoon - X11 and Closing

14:15 - 15:00  Bill and HEPiX: The implications for HEPiX
               of the rise of NT
               Animator - John Gordon/RAL
               Abstract - Various labs and experiments are
               suggesting that NT may be (one of) their
               platform(s) of choice in the near future.
               What are the implications of this for HEPiX?
               What are the integration issues? How soon will
               NT be able to provide the wide range of support
               that the HEP user can expect from unix?
