---+ LHCb Computing Upgrade

This is the entry point for all activities related to Computing for the LHCb Upgrade.
---++ Milestones

We have three milestones:
   * 2016 Q1: [[https://cds.cern.ch/record/2142436][Roadmap for the TDR (LHCb internal note)]] %RED% *-- DONE --* %ENDCOLOR%
   * 2017 Q4: Computing Technical Design Report (to be reviewed by LHCC) -- [[%ATTACHURL%/lhcb-upgrade-tdr-TB.pdf][draft for TB and collaboration wide review]]
   * 2018 Q3: Computing model for Run3 (to be reviewed by LHCC)

---++ The roadmap document

The activities related to the computing upgrade started in summer 2015, in preparation of the <a href="https://indico.cern.ch/event/337568/" target="_blank">6th computing workshop</a>, held in Paris in November 16th-20th 2015.

Five working groups were established
   * [[https://lbdokuwiki.cern.ch/upgrade:lhcb_parallelization][Hardware and dataflow]] (conveners: Niko Neufeld, Daniel Campora, Mike Sokoloff)
   * Scheduling and framework (Tim Head, Gerhard Raven)
   * Event Model (Yasmine Amhis, Roel Aaij)
   * [[https://gitlab.cern.ch/sneubert/collaborative-work][Collaborative Tools]] (Silvia Amerio, Sebastian Neubert)
   * [[LHCbComputingUpgradeDataProcessing][Data Processing and Analysis Model]] (Andrea Contu, Chris Haen)
In addition, input is provided by relevant people in the area of simulation, non-event data, external software.

A summary of the Paris workshop is available [[%ATTACHURL%/Roadmap.pdf][here]].
The roadmap has been released as [[https://cds.cern.ch/record/2142436][LHCb-INT-2016-016]], PDF available [[https://cds.cern.ch/record/2142436/files/LHCb-INT-2016-016.pdf][here]]. A summary of the document was given in [[https://indico.cern.ch/event/496903/contributions/1176024/attachments/1239872/1822905/20160308_LHCbWeek_roadmap.pdf][this talk]] at the [[https://indico.cern.ch/event/496903/][79th LHCb week]] in March 2016.

The milestones towards the TDR are the following

---++ From the roadmap to the TDR

After the release of the roadmap, a [[TaskForceCS][Task Force on Core Software (TFCS)]] was established to work on time-critical items such as the restructuring of Gaudi towards a task-based framework, the update of the event model, the evaluation and implementation of alternatives for the conditions database and the detector description.

The first hackathon of the TFCS was held on May 26-27th, just before the [[https://indico.cern.ch/event/464391/][7th Computing Workshop]].
The [[https://indico.cern.ch/event/542616/][second hackathon]] was held on July 7-8th. The [[https://indico.cern.ch/event/562730/][third hackathon]] was held on September 19-20th. The fourth hackathon has taken place in November during the [[https://indico.cern.ch/event/464394/][8th Computing Workshop]]. The [[https://indico.cern.ch/event/595667/][fifth hackathon]] was held in January 25-27, preceded by a C++ course and a tutorial session on the new framework. The [[https://indico.cern.ch/event/610957/][sixth hackathon]] was held on March 27-31. The next hackathon is scheduled in the week of June 19th.

Activities related to the TFCS are documented [[TaskForceCS][here]].

Activities in the other working groups are documented in the following pages:  
   * [[https://lbdokuwiki.cern.ch/upgrade:lhcb_parallelization][Parallelization]] (formerly known as Hardware and Dataflow)
   * [[https://gitlab.cern.ch/sneubert/collaborative-work][Collaborative Tools]]
   * [[LHCbComputingUpgradeDataProcessing][Data Processing and Analysis Model]]

More information on simulation and DIRAC are available at the [[LHCbSimulation][simulation]] and [[LHCbComputing#LHCbDIRAC][distributed computing (DIRAC)]] pages

---++ Upgrade Software and Computing Technical Design Report

The TDR is completed, has been internally reviewed (P. Charpentier, S. Stahl, U. Marconi), and is available for collaboration-wide review at [[%ATTACHURL%/lhcb-upgrade-tdr-TB.pdf][this link]].

---++ Meetings, mailing list

Meetings can be found under the <a href="https://indico.cern.ch/category/7445/" target="_blank">Computing Upgrade indico category</a>. [[https://indico.cern.ch/category/7870/][General meetings]] are held on mondays at 15:30 on a monthly basis. [[https://indico.cern.ch/category/7942/][Meetings of the TFCS]] are held every two weeks in the same time slot. Meetings of the parallelization working group are held on friday afternoon, indico category [[https://indico.cern.ch/category/7616/][here]]. The meetings of the Collaborative Tools Working Groups are grouped [[https://indico.cern.ch/category/7617/][here]].

The mailing list LHCb-UpgradeComputing-Discussion.AT.cern.ch has been setup and is open to subscriptions.
