1. Erik Blaufuss University of Maryland Data Filtering and Software IceCube Collaboration Meeting Monday, March 21, 2005

2. March 21, 2005 Data Filtering and Software – E. Blaufuss Overview Data Filtering and Software includes: –Processing and Filtering (PnF) System at Pole –Production Processing software environment Offline software suite IceTray software framework Dataclasses event containers Build system and tools –Database design and implementation Database server Access tools –Data visualization Event Viewer Root-based analysis tools

3. March 21, 2005 Data Filtering and Software – E. Blaufuss PnF System Overview DAQ Dispatch P&F Server Recon Worker X 50-60? 4-15MB/s 1500-2000Hz Tape Transient Buffer DAQ Land Raw Data Filt/RecDataFilt/RecData Online Analysis Recon Monitor Data Handling Rec/Filt Data ALL: RAW+FILT+REC FILT:RAW+FILT+REC ALL:FILT+REC Expt. Control / Logging Offline Software/IceTray

4. March 21, 2005 Data Filtering and Software – E. Blaufuss PnF system at Pole V1.0 of PnF system was deployed at Pole this past season. –Running IceTray in Online environment –Parses and decodes the incoming DAQ stream –Currently performs no reconstruction. Currently not in the Main data stream. –Lack of global run information at Pole –Lack of system-wide integration testing No PnF output sent via satellite –TestDAQ/Monolith output tarfile only output sent New version of Monolith soon (April) –Real testing of data flow to PnF (SPTS -> SPS)

5. March 21, 2005 Data Filtering and Software – E. Blaufuss PnF Plans for next year With the “Real DAQ” in place: –PnF output IS the output stream for RAW event data from IceCube DAQ. –All other non-event data will be handled by databases. After this next deployment season: –Filtering at South Pole will be REQUIRED. –Will require reconstruction/filtering modules be ready and fully tested in IceTray offline!

6. March 21, 2005 Data Filtering and Software – E. Blaufuss Offline Software Several incremental releases this past year –In use by reconstruction and simulation groups. Current release (new!): –OFFLINE-SOFTWARE V01-05-00 Full details on release, and HEAD at: –http://glacier.lbl.gov/http://glacier.lbl.gov/ Plans for more functionality and tools over the next year. More details regarding “readiness” of software later….

7. March 21, 2005 Data Filtering and Software – E. Blaufuss Databases (Mons group) DOM assembly and testing database setup and in use for FAT testing. Geometry database for String 21/IceTop up to date with Kurt’s latest numbers. –Includes “nominal” locations for other strings Preliminary version of DOM calibration DB IceTray module for DB access in place In the next few months: –Run configuration DB for data from current year –Continued integration of database into IceTray

8. March 21, 2005 Data Filtering and Software – E. Blaufuss Visualization Event viewer in place –Animations –Fits, features, readouts Root analysis Tree tools in place –Fit/reconstruction level analyses –Waveforms, features, hits level analyses Plans for more over the next year.

9. March 21, 2005 Data Filtering and Software – E. Blaufuss Current State of Offline SW (Is it “analysis ready”?) IceTray software Framework –Has been released for ~1 year. –Can handle single events in a linear chain of modules More advanced module topologies planned this year Dataclasses event storage classes –Have been released for >9 months. –Designed for storage of IceTray DOM data Amanda data (treat as stand-alone/together) Reconstruction results Geometry, calibration, monitoring structures, more…

10. March 21, 2005 Data Filtering and Software – E. Blaufuss State of Software (cont’d) –More extensions planned as need dictates. –Can hold TestDAQ data from this year I/O routines for IceCube data –Monolith-reader can decode data from Pole. –Triggered events from South Pole in dataclasses –Basic functionality is there. Includes domcal information (Thanks Dima…) Still some work to do (trigger ID, run ID, etc) Run “meta-data” – Run configuration info. –Data exists (files), but documentation and wider understanding is minimal. –Need docs, fill run configuration database to make properly available for analysis in IceTray.

11. March 21, 2005 Data Filtering and Software – E. Blaufuss State of Software (cont’d) Cleaning, feature extraction –Basic functionality in place and working Hit selection/cleaning FeatureExtractor (Dima) –Advanced cleaning needs to be implemented Amanda specific: Cross talk, flare checking, etc. Plans for that in next few weeks with Peter Steffen and others Reconstruction –Basic algorithms are done (and reviewed!) First guess (linefit, dipole, c-first, TOI, JAMS) Standard Log-likelihood for muon tracks –Advanced (exotic PDFs, iterative fits) needed

12. March 21, 2005 Data Filtering and Software – E. Blaufuss State of Software (cont’d) –Cut parameters/observables Work has just started here and much remains. Filtering capabilities –Currently possible to use linear chain of modules to reduce data files. –Branching of flow in modules planned for this year. Allow muon and cascade recos in same chain. Needs a “decision” module Amanda –Full support for calibrated F2K files Includes TWR in F2K files

13. March 21, 2005 Data Filtering and Software – E. Blaufuss State of Software (cont’d) –TWR readouts (non-F2K) support this year –Working towards being ready to merge AMANDA/IceCube data this summer. IceCube and Amanda data are both handled naturally together in IceTray/dataclasses. Simulation (Significant driving force in the design and requirements for IceTray.) Merging input frames to overlay events –Currently developing simulation releases against OFFLINE-SOFTWARE releases.

14. March 21, 2005 Data Filtering and Software – E. Blaufuss String 21 Data – A few plots

15. March 21, 2005 Data Filtering and Software – E. Blaufuss String 21 Data – A few plots More like this in Gary’s talk

16. March 21, 2005 Data Filtering and Software – E. Blaufuss Status Summary For example… Is….Work provided by… Core SoftwareIceTray, Dataclasses I/O V1 of all ready and being used UMD, LBNL, UDel Core UtilitiesDB access, File readers, eventviewer 80% done, all in a usable state UMD, Mons, LBNL, Dortmund Application Software Reconst., Filtering, Calib, Sim. Work is underway (some useable) Entire Collaboration

17. March 21, 2005 Data Filtering and Software – E. Blaufuss Status Summary (2) IceCube Offline software effort needs more: –Users –Developers of applications –Feedback, bugs found, documentation readers, etc. We’re providing the framework and some tools. –Real work of providing reconstructions, analyses, simulations will be the work of the entire collaboration. Start using it. It’s ready. –There are many ways to help out in software.
