A Free sample background from www.pptbackgrounds.fsnet.co.uk Slide 1 LEIR Application Project LEIR Applications is a separate project LEIR Applications is a separate project –Purpose: provide LEIR specific applications –Duration: 2004 – 2006 (to be confirmed) –Common effort OP − CO Mixed team (preliminary) Mixed team (preliminary) –Fabio Follin, Anthony Rey (OP/SPS) –Jose-Luis Sanchez, Almudena Solero (OP/PSB)  on shift in 2005! –Philippe Malacarne, myself (CO/AP) Users who specify requirements Users who specify requirements –Michel Chanel, Christian Carli (ABP) –Sergio Pasinelli (OP) What happened so far (this year) What happened so far (this year) –Agreement on roles and responsibilities between OP and CO –Draft project description written and circulated –Preliminary team appointed –Started participating in requirements brainstorming sessions

No fall-back solution! Unification PS + SL Unification PS + SL –“Cultural differences” need to be addressed –Similar (but different) solutions and habits exist on both sides –  A lot of compromises and adaptation work are needed! Many new solutions are used for the first time operationally Many new solutions are used for the first time operationally –First project to operationally use the merged controls approach put in place for the LHC era software (SPS, CESAR, LHC) –Many sections/groups provide new developments (“Last chance for operational validation before LHC”) –Will everything be ready? Will it work? –Our goal is to provide reliable software (not to debug new solutions) Not enough man power (especially from ex-PS side) Not enough man power (especially from ex-PS side) –This is a machine in the PS complex, after all

A Free sample background from www.pptbackgrounds.fsnet.co.uk Slide 4 Approach We have to reuse existing components wherever possible We have to reuse existing components wherever possible –We don’t have the resources to reimplement everything –We’ll try to choose the best existing component for each functionality LEIR ≠ CESAR LEIR ≠ CESAR –We wont try to “copy-paste” CESAR to LEIR –Different requirements  different applications BUT: we have to use the same solutions where possible BUT: we have to use the same solutions where possible Examples: Examples: –Standard Controls Architecture –LHC-era settings management (~ “PS archives”) –Common Console Manager –JAPC (Java API for Parameter Control) (~ “PS ASC”) –ASC Beans (to be ported to JAPC) –Java Knobs and Working Sets –JDataviewer + Gui Platform (GP) Components –…–…–…–…

A Free sample background from www.pptbackgrounds.fsnet.co.uk Slide 5 Existing Applications We have to use existing applications We have to use existing applications –Written in Java and C/C++ –Need to be adapted / restructured / enhanced / finished Examples of existing applications Examples of existing applications –Jorg’s orbit correction application –Jose’s beam injection application –Jose’s Tomoscope (or Bunch shape measurement) applications –…–…–…–… A “terrible mix” of approaches and technologies?! A “terrible mix” of approaches and technologies?! –This is a compromise! –A lot of adaptation and plumbing work will be necessary Decision whether to reuse is based on various elements Decision whether to reuse is based on various elements –Effort for adapting and integrating a given existing application –Effort for maintaining heterogeneous solutions –Effort for re-writing the application

Finish and publish project description Finish and publish project description –Clarify responsibilities and collaborations –Agree on milestone plan –Discuss and settle many details Continue to gather and analyze requirements Continue to gather and analyze requirements –Prioritize requirements in agreement with users –Identify and mitigate risks –Study existing components and applications Complete and confirm team Complete and confirm team –People from ex-PS side who are not on shift in 2005 Work on CESAR is our priority until Summer 2004 Work on CESAR is our priority until Summer 2004
