Presentation Transcript

  1. HST Data Processing Operations and Engineering Division Data Systems Branch Mark Kyprianou

  2. Highlights - Infrastructure • Deployed database clustering technologies to DADS/OPUS systems • Internal and Public databases • Improve uptime, reliability and performance • Updated/added new web servers • 3 independent environments: • Dev, Test and OPS • Allows for isolation in the software life cycle

  3. Highlights - Instruments • Science data processing enhancements • Astrodrizzle (ACS and WFC3) • CALACS w/CTE • COS reprocessing/cataloging enhancements • CALCOS with no IRAF • STIS flight software problem with time tag data • STIS Reprocessing to create valid CCI files for post-SM4 data

  4. Retrieval Times

  5. Future Development

  6. Future Development • Infrastructure • Red Hat OS upgrade for DADS/OPUS servers • Purchased NAS storage (EMC Isilon) • Very scalable for Big Data • Blades support • High IOPS • CPU processing • Storage

  7. Future Development • Instrument Data Processing enhancements • Keywords • Algorithmic enhancements • Reprocessing planned for ACS, WFC3 and COS • Iraf Free: WFC3 and STIS • In test

  8. HST Upgrade Projects

  9. HST Upgrade Projects • Background Automated Reprocessing (BAR) • Integrated reprocessing • Online cache • Workflow Manager (WFM) • Technology refresh for work flow processing • Calibration Reference Data System (CRDS) • Driven by analysis of current systems targeting JWST • HST Mission Office elected to adopt these enhancements

  10. Background Automated Reprocessing (BAR) • Handle reprocessing activities in an integrated fashion • Use prioritization scheme to control processing sequence • Provide online access to files • Enhance tiered file storage sub-system • Store data to provide direct access • Rework file handling to be mission independent

  11. Work Flow Manager (WFM) • Upgrade workflow processing • OPUS technology refresh is over due • Limited functionality for expansion (cloud computing, additional compute resources) • Condor: Open source, high-throughput computing software framework has been selected • Allows to access compute resources on different levels/rules

  12. Overview: BAR/WFM/CRDS

  13. Current Status • BAR • SDPQ - complete • File Storage to online cache – in progress • Working on distribution updates • WFM • Condor • Enterprise level, Open source workflow package • Open Workflow Language (OWL) • Blackboard, template for data centric processing • Shoveler - complete • Prototype CALACS pipeline • Continued development thru FY13

  14. Questions/Comments
