DAQ “Design” Workshop

Dave Newbold, Georgia Karagiorgi 30-Oct-17

Welcome!

• Especially to those who travelled a long way at short notice
• Even so, please keep your talks to time!
• My thanks to our host Georgia, who has organised everything
• Goals of this workshop:
• Identify the physics requirements on the FD (SP + DP) DAQ
• Identify pre-existing technical constraints on the DAQ design
• Learn about existing technical solutions from other experiments
• Narrow down to a few possible architectures as candidates for TP
• Agree a ‘decision matrix’ which will examine the merits of each
• What we need to achieve
• Everything should be on the table here, but by ~Jan need baseline decision
• From now on, work should be on one or more concrete DAQ designs
• Meaning, we also need the tools to undertake that design process
• Our Technical Proposal draft is needed by ~March (to be confirmed today…)

CAVEAT EMPTOR: the details are definitely
 wrong in many respects

Some Motherhood Thoughts

• We need a flexible, scalable system
• We really don’t know how requirements or detector performance will be
• We need to able to add selection / filtering / event building capacity at any time
• Schedule is tight – need to ‘design for construction’
• Meaning: modular and partionable system, designed for self test
• Meaning: avoid schedule interaction with other FD components
• A single system should serve SP + DP + ???
• Though the interfaces may be quite different at the front end
• Good ideas are great, proven and deployed good ideas are even better
• We will have only ~1 year to demonstrate and document everything for the TDR
• Need to respect resource constraints
• Unless some good news, this is a $10M system for det. #1, #2
• We need to identify and agree off-site bandwidth and datasets
• Reminder: 100Gb/s is 0.5PB/year
