2017 Milestones – On-line HW Acquire on-line HW 2 L0 servers 2 L1 servers with storage (~40TB) 2 Network switches Rack and cabling Define UPS for experimental area (computing, electronics, HV) Create on-line infrastructure Define location of L0/L1 Define realistic count of network ports needed Servers, trigger, DCS, sensors, … Lay out cabling Create 10Gbps link to LNF-IT 18/01/2017 E. Leonardi - PADME G.M. - TDAQ & Computing

2017 Milestones – On-line SW Define production DAQ procedures Define main DAQ strategy Now: each ADC board is acquired asynchronously Can we use a trigger-oriented DAQ (all boards acquired after each trigger)? Multi-server RunControl Integrate trigger information Integrate TimePix3 data stream Verify event merger with >2 ADC boards How do we merge TimePix3 data? 18/01/2017 E.

E. Leonardi - PADME G.M. - TDAQ & Computing 2017 Milestones - Trigger Create Trigger/Clock infrastrurcture Preliminary requirement for the PADME L0TP are defined Deeper understanding of V1742 board necessary Needs dedicated man power to start implementation studies and project soon. Is an evaluation board+analog Mezzanine suited for the PADME L0TP? 18/01/2017 E. Leonardi - PADME G.M. - TDAQ & Computing

E. Leonardi - PADME G.M. - TDAQ & Computing 2017 Milestones - GRID Port PADME SW to the GRID Install padme-fw to CVMFS Verify interaction with standard G4/ROOT libraries Enable PADME support at selected sites LNF, CNAF, Sofia, Roma1… Create VO roles, register production/standard users Set up automatic data transfer LNF → CNAF CNAF already accepting PADME data (manual or automatic transfer) Create GRID-interfaced transfer server at LNF Allocate GRID/off-GRID CPU power at LNF Tier1 Define utilization of KLOE tape library at LNF 18/01/2017 E. Leonardi - PADME G.M. - TDAQ & Computing

E. Leonardi - PADME G.M. - TDAQ & Computing 2017 Milestones - Software Finalize MC digitization Define digi structure and digitization procedure for all detectors Verify processing times/data output Release Reconstruction SW Finalize infrastructure Create reconstruction example Define reconstruction procedures 18/01/2017 E.
