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…) 2

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 4
