Data Handling

Peter Steinberg

DAQ & DAQ GUI• Andrei & Pradeep• GUI (Pradeep)

• Shift mode as of Wednesday• Documentation coming

• Functionality• silicon, latchup, rocdb, FBTIME/PED

• Distributor & DAQ & ROCDB play nice• Crash recovery• Todo

• Trigger configurations not yet downloaded into L0/L1 managers

• Need Trigger config synced w/ DB

Peter Steinberg

Distributor & Data Mover, etc.• Burt• Distributor in stable state

• DAQ work has improved things

• To do• Hunt down remaining segvios• Hanging-socket problem in DAQ• Document & bullet proof client that runs modules

(needed for online processing)

• Data Mover• X2 rate by concurrent checksums, x2 from

multithreading expected

• Pedestals• Datamover now starts ped running

Peter Steinberg

Data Validation

• Data Validation• 8 hour jobs with 1 GB files• Do we plan to increase this?• Intense need for profiling and optimization

• Compacting files• When do we write all collisions?• Zero Suppression• Writing out Object Managers every 10 files

• MBT Monitoring instabilities in DV, HPSS• Reference histograms?• Consolidate output files: AnT Maker?

Peter Steinberg

Event Display

• “phever” – online trigger event display

• Currently getting “raw” events from the distributor• Separate trigger processing envisioned• Better response from phever

• To do• Incorporate expert plots• Get alarm requests• Compiled version• Printable summary plot if needed

Peter Steinberg

Detectors

Peter Steinberg

Trigger

• Dave et al• Online client needs to be tuned for this

year’s data• Lots of items integrated into event display

• Aneta writing TrgInspector• Will keep processing TrgTrees and

InfoTrees to monitor health of trigger

• Trigger info on the web• Trigger info in the data

• TrgEventData still being updated• TrgTrees have all the new detectors

Peter Steinberg

Plastics

• Frank• Calibrations

• New triggering makes old TOF calibration procedures suboptimal

• FB works fine

• Calibrations that need DV output are highest priority to fix

• Online clients will come next• What about catching bad TDCs?• Inkyu’s client is useful, but needs more

interaction to determine optimal settings

Peter Steinberg

PCAL• Corey & GSFS• Tasks finished

• VME unpacking, PCAL Event data, TrgTrees, Calibrations, event display

• Todo• Online monitoring clients• Online pedestals • Raw branch in TrgTree

• Longer term• PCAL gain calibrations• Geometry in PMC• Full MC implementation

Peter Steinberg

SpecTrig

• Gabor• Done

• Online client running – no monitoring• Some detector checks, not automated• Trigger bits are in data (TDC & Latch)

• Todo• Data tracking – collaborate w/ TrgGroup• Dealing with trigger mixes• VME data in event, trees

• Longer term• Time calibrations?

Peter Steinberg

Silicon• Gerrit, Rachid, Christof• Online latchup clients still running – no

changes expected• Pedestals hard-wired to run on sequence 0.

Gerrit will deal w/ reference sets• No more calibration runs (DAQ issue)

• Running with master gain file from last year• Not automatic – just “replacing” file as needed

• Running fine in DV – DCM main issue• Will continue to not apply it to final hit arrays• Some controversy about access?

• Silicon processing not finished• Rings still done the old way (Yuriy)

Peter Steinberg

Analysis Infrastructure

Peter Steinberg

Geometry

• Adam (geometry), Andrzej (access)

• Big change: geometry from DB• Unfortunately, tripped off bug in phat• Back to file access

• LatestGeometry will be retired• Can get “latest” by PR0x run

• Some issues with dealing with frames and supports of new detectors

Peter Steinberg

DB Access

• Still GAH’s code, KG & BW • Serious issue with dangling cursors in Oracle• Kris & Bolek working w/ Marguerite to debug• GAH put in “auto-connecting” in DB software

– not good behavior• KG proposes to remove, but this will wait until

things stabilize

• Kris will put up web page explaining how best to use TPhDatabase

• No comment yet on DbKeys…

Peter Steinberg

Phat][

• Maarten & Peter

• Slowed due to work on the run

• Finishing up retooling of modulelib

• Macros will be imported at a minimal level – if you need it, import it!• Old macros will obviously be in Phat6 CVS

• Volunteers coming on shell

• Trivial to check out of CVS

Peter Steinberg

AnT Trees

• Maarten & JWL

• This will be the main mini-DST format• Trigger information for event selection• Hits & Tracks• No multiplicity details planned

• Need requests for more functionality• (me) Make it modular so it’s easy to add

objects as branches (a la EventInfo)

• Integrate more of the needed data

• Add to production

Peter Steinberg

Data Accessibility

• Maarten & Jinlong• CatWeb

• Managing 130,000 files, 175 TB• 3 disk pools (RCF, Pharm, PDEV)• 50k file instances (16 TB)• 300,000 accesses of file instances via TPhDST• 2-5% staging error rate (HPSS, RCF, user

problems)

• Plans• Filesets, gui improvements, improve job

scheduling, disk cleanup features• Have phat speak to CatWeb server, not Oracle

Peter Steinberg

Analysis

Peter Steinberg

Data Tracking

• Dave et al

• No consistent data tracking scheme created yet

• Pradeep will update scripts doing run totals online• PAS has already written scripts using the

DAQ-generated run totals (vs. B)

• Scalers in the data stream• Need verification and matching to visual

scalers

Peter Steinberg

Event Selection

• Dave et al

• Done by macros at the moment• Full IsCollision(), suitable for DV, coming

early next week

• Centrality cuts released to collaboration• First round from richard• More to come

• Not clear how to handle trigger mix• Major issue for recombining different

hardware data selections

Peter Steinberg

Tracking

• Conor & Abby, DV by Jang-Woo

• New supermodule planned• PR03LowMultTracking

• Major changes• Vertex-less straight tracking• Then vertex from straight tracks

• Changes related to new field map

Peter Steinberg

Vertexing

• Andrzej & Krszystof• All vertexing procedures work

• Single track vertexing not yet in phat, but clearly crucial for d+Au and p+p run

• OctDeVertex: 90% eff, 1-1.5cm res• OctagonVertex: 80% eff, 2.5cm res• Zvertex: 35% eff, best y• SpecMainVertex: 10%

• Forcing OctagonVertex to agree w/ OctDeVertex actually reduces purity of other vertices

Peter Steinberg

Conclusions• Data Handling

• Trigger configuration in DAQ• Data file sizes / production time

• Detectors• Monitoring, monitoring, monitoring • Si silicon processing (e.g. rings) not complete• TOF calibration infrastructure crucial

• Analysis Infrastructure• Phat][ imminent• DB stability potential production problem

• Analysis Software• Event selection, vertexing, tracking all coming on
