Description
Technical Evolution Groups – Mandate
To reassess the implementation of the grid infrastructures that we use in the light of the experience with LHC data, and technology evolution, but never forgetting the important successes and lessons, and ensuring that any evolution does not disrupt our successful operation.
 
The work should:
  • Document a strategy for evolution of the technical implementation of the WLCG distributed computing infrastructure.
  • This strategy should provide a clear statement of needs for WLCG, which can also be used to provide input to any external middleware and infrastructure projects.
 
The work should, in each technical area, take into account the current understanding of:
  • Experiment and site needs in the light of experience with real data, operational needs (effort, functionality, security, etc.), and constraints;
  • Lessons learned over several years in terms of deployability of software;
  • Evolution of technology over the last several years;
  • Partnership and capabilities of the various middleware providers.
It should also consider issues of:
  • Long term support and sustainability of the solutions;
  • Achieving commonalities between experiments where possible;
  • Achieving commonalities across all WLCG supporting infrastructures (EGI-related, OSG, NDGF, etc).
Deliverables
  • Assessment of the current situation with middleware, operations, and support structure
  • Strategy document setting out a plan and needs for the next 2-5 years
Databases Working Group Topics
The bullets represent the topics that should be included in the discussions, but are not exclusive.
  • NOSQL vs Oracle, MySQL, etc
  • Frontier, squids, vs 3D/Streams, GoldenGate, DataGuard etc
  • CORAL, COOL
  • What is framework for deploying new applications that need a DB? (e.g. if dev has used a random db, how is that made into a service?)
----------------

We do not want to repeat information from the June 2011 Database Futures Workshop (http://indico.cern.ch/conferenceTimeTable.py?confId=130874), especially things describing the current situation, although a quick refresher on plans shared then can be helpful.  We want to focus on what should be changing over the next 2-5 years, both things currently planned and especially things not yet planned but which are lacking or could be improved or could be better shared between experiments.  Bring proposals, or describe ideas during discussion time, or at least talk about what the needs will be if not the solutions.  Set your sights on after the long 2013 shutdown and later.
