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-cases”of the experiments
in view of giving requirements for middleware release and
development

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 nonHEP applications.

WP8 TWG Tasks (2)
–
4.Definition of the 'sample' applications requested by the Testbed. 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

WP8 TWG Document
• In preparation “ Planning Specification of GRID services
(HEP User Requirements and Use-Cases)”
• Draft document (no ATLAS parts yet) in
http://www.mi.infn.it/~perini/twg-v0.2.pdf
• 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.)
