News from EU DataGrid

• What happened from last meeting (Nov.30th)
• What is going to happen next
• What to do for ATLAS

DataGrid official start

• The EU project DataGrid has started January 1st
• The contracts with the foreseen level of founding
  ( 10 M Euro) , were signed just in time in
  December
• The project duration is 3 years as foreseen
• The funding covers only the personnel for
  middleware development

Meetings in December

• 11th in Milan WP6 meeting
• Start to organise the sites and the Grid s/w
  releases
• see site http//marianne.in2p3.fr
• 19th at CERN WP8 TWG meeting
• first meeting to present short term use-casesof
  the experiments in view of giving requirements
  for middleware release and development
• interim L. Perini present (presentation in
  www.mi.infn.it/perini/atwp8-19dec00.ppt)

WP8 TWG

• It was agreed that WP8 set up a Technical Working
  Group (TWG) composed of one application software
  expert from each experiment and from ESA (WP9)
  and biology (WP10), plus the WP8
  experiment-neutral personpower in the different
  partners (5 people).
• This WG will be chaired by the CERN WP8 person
  who will act as the WP8 architect (Ingo
  Augustin) and will have the task in the next
  slide.

WP8 TWG Tasks (1)

• 1.Help the WP8 architect to collect the
  requirements from the experiment ESA and Biology
  to present them in the ATF.
• 2.Liaise with the Middleware WP's (1-5)
  regarding the services required by the
  applications, and the definition of the
  appropriate interfaces.
• 3.Discuss WP8 architectural questions. It is an
  open question as to whether, for example, the
  HEP experiments require an 'upper middleware'
  layer, common to all experiments, running over
  the middleware services, or whether the
  interface to generic middleware services
  directly. Similar questions arise the non-HEP
  applications.

WP8 TWG Tasks (2)

• 4.Definition of the 'sample' applications
  requested by the Test-bed. Both CMS and LHCb feel
  they can offer some existing running distributed
  application for discussion with the middleware
  groups. ALICE and ATLAS will see whether they can
  add their own applications. This WG will look at
  this in detail.
• 5.Define what is required, especially in the
  short term, from the Test-bed environments. This
  group would provide technical liaison with the
  Test-bed and Networking workpackages (e.g. attend
  their meetings). Special priority points are,
  for instance
• 1.Provision of Standard, Supported, Documented
  Globus installation kit
• 2.Definition of Test-bed sites and contact
  people
• 3.Definition of Certification system to be
  employed by the datagrid project

WP8 TWG role and ATLAS action

• This sub-group should be as compact as possible,
  to be able to meet, virtually or in person, in
  its own right, preparing our point of view for
  the global Test-bed and Architecture meetings.
  The experiment TB rep, unless the same person,
  would normally not attend, unless briefing was
  required for a forthcoming TB meeting. The
  frequency of meetings will be at the discretion
  of our architect and the WP8 coordinator.
• ACTION Nominate TWG ATLAS Representative

• Need to write for ATLAS
• Short description of short and long term
  Use-Cases
• Requirements for short and long term Use-Cases
  (filling template)
• Short summary list of HEP application
  Requirements
• First job for new ATLAS TWG person serious help
  expected from myself et al. involved ( R.Baker
  etc.)
