3. March 21, 2005 Data Systems Overview Data Handling Accomplishments –South Pole Test System operational since late last year. –South Pole System installed at the Pole in late December. –SPS operational with 1 string! –SPADE installed at Pole and used to transfer drill, webcam, and TestDAQ data. Coming Year Activities –Data ingestion to Data Warehouse to be implemented. –Web interface to Data Warehouse. –Upgrade data storage facilities. –IceCube Metadata standard and data directory structure to be defined. –Upgrade SPS and SPTS for upcoming season.

4. March 21, 2005 Data Systems Overview Experiment Control Provide system for South Pole operating –Control –Configuration –Monitoring –Logging –JBoss Support Based on “JBoss” –Infrastructure in place –Run-Control JMX Console in development

5. March 21, 2005 Data Systems Overview Filtering PnF System –V1.0 Tested at SPTS & deployed at Pole –Currently not in data stream Lacking some run information and testing –New Version of Monolith soon (April) Test & run PnF at Pole in preparation for next year Plans for next year –Integrate with Real DAQ,Exp Ctrl, DAQ Disp, SPADE at SPTS (August/Sept) PnF is output stream for Real DAQ Filtering at South Pole required

6. March 21, 2005 Data Systems Overview Offline Software Several incremental releases this past year –In use by reconstruction and simulation groups. –Many people developing physics modules –Lots of physics to do yet Current release: –OFFLINE-SOFTWARE V01-05-00 There are tools available for all –Event viewer –Script to make histograms for ROOT AMANDA muon reconstruction and merging by summer
