Possible offline software organisation in UK

1. ATLAS Software ReviewConcluded many things / annoyed many people

......but....

Stated aim is to ‘globalise’ software, so that effort from around world can be tapped properly.

Idea of MOUs for some software tasks has emerged

Therefore opportunities , to reconsider UK offline software contribution

and particularly to develop OO sector.

Background:

2. In ATLAS M.C. external members of committee commented:•UK software effort does not seem to be very coherent ?•Concerned that we dont have a ‘plan to reach a plan’ of computing/software model

some questions:

1. Is UK based coordination needed ?

2. Would we be better concentrating effort on some obvious sectors related to SCT ?

3. Do we want to prepare to ‘bid’ for some real virgin ‘deliverable’ with an associated MOU.

4. Is it just a question of PR-defend non- national based virtual groups -presenting what is done already in more coherent way- pseudo MOUs-play active part in development of computing/software model

Individualsworking in virtual

groups Not UK based

Choose to work more closely in UK on some few

projects

Some software tasks I know of which have UK connections/potential:

Geant-4 Simulation of SCT

Taskleader: Jo Pater

Contributors: Steve Snow, Chris Lester, Bill Murray, Tim Brodbeck+others at Lancs

Observations:

Fairly virgin ground

Very important and highly relevant to UK interests

Internationally co-ordinated by Jo at CERN

Probably doesnt need UK meeting layer ....but...people tospeak to are a always useful

Strongly suggest we always write a joint reporton this to the UK MC !!!

We could identify this as a ‘core’ UK area and encourage some others in

UK to join

Alignment using tracks

Taskleader/Organiser: Steve Haywood

Contributors in UK ?

SCT database

Taskleader Jo Pater at present

Contributors in UK ?

Observations:I presume this covers production => physics

I presume it needs a core of Objectivity experts + mechanical experts

OO Reconstruction and analysis framework (ARVE and evolutions)

Coordinator : TBA

Contributors:D.Candlin, R.Candlin, ?????sorry - who else in UK?????

Comments:

ATLAS Needs this !

Bona fide offline software contribution iin OO sector

I suggest that any new physics interest could be pushed to do itin OO framework

=> push it forward by users=> lead to contributions to this area

Software production process (ASP & evolution)

Dont know what to say here except that UK peoplehave been invloved in this, and sent unified letter to MCand ATLAS

=> this prior effort and feeling should be respected

=> this expertese should continue to be used.

Some personal observations to lead into discussion

OO sector is certainly long term future and lots of work is needed => opportunity for new (and old) blood

Management is acutely aware that it must changeperception or fact that ist difficult to do anythingquickly in this sector - so it WILL become easier.

Now is a good time for us to at least review how best UKsoftware effort might be applied to the ATLAS software needs.

SCT simulation looks like a de-facto area we should back

OO reconstruction framework looks interesting (naive view: links offline software with physics analysis)
