                 Tony Cass               

12:30 - 14:00  Lunch
14:00 - 14:30  L3-data analysis on an IBM RS6000 cluster 
               Speaker - Frank Behner/ETH Zurich

14:30 - 15:00  FARFALLA (C++ hep data manager)  
               Speaker - Chris Walter/Caltech
               This talk follows the CHEP talk on this project which described
               the procedural user interface. In this session, the speaker
               will present an overview of the package or mention some 
               specific things which might be generally useful; such as a 
               small modification to the way they handle XDR data to allow 
               the writing of short-data (from camac 16 bit operations for 
               example) without the normal XDR 2 byte overhead.  [XDR is a 
               standard for writing binary data in a machine-independent way.]

15:00 - 15:30  Developments with the HEPiX Shell Startup Scripts  
               Speaker - Axel Koehler/DESY
               Much work was done on these two scripts during a joint
               development between DESY and CERN including the addition of
               a Makefile, the production of more documentation, adaptions
               for use with AFS and the addition of a code management system
               which should enable different sites to make use of a single
               set of source modules henceforth.

15:30 - 16:00  Break

16:00 - 17:00  LBL Computer Colloqium
               The evolution of Software in HEP: A strategy towards LHC 
               Speaker - Rene Brun/CERN
               Abstract -
               The experience with software in the existing large experiments 
               has demonstrated the need for long term planning and a careful 
               choice of the essential tools and technology. We are now 
               preparing the ground for a new generation of experiments to be 
               run at the LHC. In the talk, I will go through some of the 
               ingredients of a possible strategy:
               - The evolution of the existing environment and tools
               - The impact of Object Oriented paradigms on our data 
                 modelling techniques      
               - A multilingual environment
               - A common framework between Simulation, Online filtering 
                 and monitoring, Reconstruction and Data Analysis.
               - The Data Storage and Data Analysis model
               - The Teams model in a worldwide experiment

Evening        Conference Dinner
               Exact time and arrangements will be announced at the
               Conference. Please sign up for this in advance.

               Abstract -

14:00 - 14:30  Migration of CERNVM, status and plans
               Speaker - Miguel Marquina/CERN
               With the decision to migrate the CERN physics community off 
               the CERN IBM mainframe we have started a gradual run-down of 
               the CERNVM service in both the batch and the interactive areas. 
               It is expected that many physics users will move to UNIX-based 
               systems and a UNIX Migration Task Force has been established. 
               This talk will cover the initial studies carried out by that 
               task force and report on their status at the time of the 

14:30 - 15:00  UNIX Product Support at Fermi - discussion of UAS and the 
               structure we are putting in place 
               Speaker - Steve Wolbers/FNAL
