2. ATLAS TDAQ Overview

3. Overview of FY06 TDAQ M&O Activity
TDAQ Construction Project continues beyond CD-4A.
Most hardware acquisition and installation in FY06-07
Much software development, esp. HLT, continues.
TDAQ M&O activity overlaps with Construction in FY06-07.
Construction Project ‘labor’ is ramping down quickly.
FY06 is first year of ‘significant’ M&O activity.
FY06 M&O activity focuses on DAQ & HLT Infrastructure s/w.
TDAQ M&O activities can be classified as:
Hardware commissioning
Hardware maintenance
Software commissioning
Software maintenance
Operations
Detector support
TDAQ support

4. HLT/DAQ Component View

5. Pre-series Hardware

6. FY06 Hardware Commissioning & Maintenance
Complete commissioning of Pre-series system
10% scale of final system w/ components of final specs
Commission final RoI Builder hardware
Commission DAQ infrastructure
Network infrastructure (large central switch) - connectivity to ROS’s
DAQ processors - SFI’s, SFO’s, L2SV’s, pROS’s
Racks & rack instrumentation
Initial complement of HLT processors - late in year
Hardware Maintenance
Pre-series system
RoI Builder
DAQ infrastructure
Test beds - particularly “performance testbed”

7. Software Development: Transition to M&O
The Combined Test Beam Release of HLT/DAQ software was nearly complete with respect to DAQ and HLT Infrastructure functionality.
This release was commissioned, operated, and maintained for the 2004 ATLAS CTB Run.
Subsequent development of this HLT/DAQ software consists of:
Added functionality (e.g. fault tolerance & error recovery)
HLT selection algorithm development
Refinement of existing code based upon CTB and subsequent experience and feedback
Development of added functionality and algorithms is Construction Project activity.
Refinement of existing code is M&O activity.
Starting in FY05, software development is increasingly M&O.
After first physics run, software development will be entirely M&O.

8. FY06 Software Commissioning & Maintenance
Commissioning of new functionality
Examples of U.S. activity:
LVL2 Supervisor and RoI Builder software
DAQ software
Monitoring
Inter-process communication and Information Services
Message passing
HLT Infrastructure software
Run Control & Supervision
LVL2 Steering
EF Dataflow
Software Maintenance
Maintenance of above (bug fixes, releases, TDAQ/Offline consistency)
Incorporate new functionality based upon experience

9. FY06 Operations Operating DAQ infrastructure in USA15 and SDX1
in support of Detector (and TDAQ) commissioning
Network administration
System administration (DAQ and HLT computer systems)
TDAQ support teams will start rotations once level of activity at Point 1 demands

10. FY06 Detector & TDAQ Support
Detector Support
ROD Crate DAQ maintenance and support
Support for:
Detector-specific software development, e.g.:
ROD software
Online histogramming & monitoring
Detector commissioning
Detector calibrations (and test beam runs ?)
TDAQ Support
Support development & commissioning of other TDAQ subsystems
Examples:
SRB support for commissioning LVL1 trigger subsystems
Integration of HLT vertical slices
Network support for Dataflow performance tests

11. FY05 M&O Activities Hardware Commissioning Hardware Maintenance
Pre-series system, including pre-series RoIB
DCS for TDAQ racks
Planning for TDAQ infrastructure commissioning
Hardware Maintenance
Set up RoIB test bench
TDAQ test bed maintenance & administration
Software Commissioning
Releases, release testing, release testing procedures
Software Maintenance
Maintain code authored by U.S. members, e.g.:
Message passing, Information Services, Online Histogramming,
HLT Steering, HLT Control, Monitoring
Synchronization of releases with Offline
Adapt/port code to new compiler and new CERN Linux

12. FY05 M&O Activities – p. 2 Operations Detector Support TDAQ Support
Completion of CTB run
System administration planning
Detector Support
TileCal beam test
Monitoring
Support of production and simulation of test beam data
TDAQ Support
Support integration with RoIB in CTB
Support of HLT algorithm integration
Test bed setup in UK, Dubna

13. M&O Planning Methodology/History
Experience in FY04, particularly CTB, indicated prior estimates of M&O effort were low.
New bottoms-up estimate of M&O effort in Jan. 2005
By “new kid on block”, w/ input from all involved
Based on effort needed for commissioning and ongoing maintenance of hardware & software components delivered by U.S.
Constructed matrix of effort per component vs. time
Estimate larger than prior estimate => add Management Reserve
MR added covers ~1/2 of increase in estimate
Checked total estimate w/ 20% of top-down estimate for ATLAS
Coordinated w/ TDAQ Management Team

17. FY06 Management Reserve FY06 MR priorities (in rough priority order):
Hardware commissioning: 0.25 => 0.5 FTE
Software commissioning: 0.25 => 0.5 FTE
Hardware maintenance: 0.5 => 1 FTE
TDAQ support: 0.4 => 1 FTE
Operations: 0.3 => 1 FTE
Detector support: 1 => 2 FTE
SRB: 1 => 1 FTE; Software maintenance: 2.5 => 2.5 FTE
Total: 6.2 => 9.5 FTE ~458k$
Impact of MR:
Improved readiness of TDAQ for cosmics and beam
Improved efficiency of detector commissioning
Improved tools for detector monitoring
More efficient HLT/DAQ operations
Improved efficiency of operations due to s/w enhancements
Without MR funds, either or both:
Reduced DAQ support for detectors, with delays in detector commissioning
Reduced effort on ongoing HLT/DAQ development, with delays in completing critical software
