Presentation Transcript

  1. HMI Status • HMI is virtually done. • Virtually  similar to but not in fact • Front window issue resolved, flight window now at LMSAL will be installed next week • Light leaks to be fixed next week. • Some electronics boards need conformal coating • Some software issues remain • Vibration and EMI/EMC testing done • Thermal Balance and Thermal Vacuum testing starting week after next. • In Air and Vacuum Calibration next few weeks. • Pre-Ship Review set for 25 Sept. • Ship date estimated 5 October. • Launch date slip to probably 15 Jan 2009 pending review at HQ. • Some serious implications from delay

  2. JSOC-SDP Status • Capture system complete, waiting testing with DDS at White Sands • DRMS and SUMS virtually done • Level-0 work progressing, to be done by delivery • Level-1 work to start after delivery • Getting serious about work on basic pipeline modules

  8. Pipeline batch processing • A pipeline batch is encapsulated in a single database transaction, “DRMS session”: • If no module fails all data records are commited and become visible to other clients of the JSOC catalog at the end of the session • If failure occurs all data records are deleted and the database rolled back • It is possible to commit data produced up to intermediate checkpoints during sessions Pipeline batch = atomic transaction Module 2.1 Module N Commit Data & Deregister Module 1 Register session … DRMS API DRMS API DRMS API DRMS API DRMS API Module 2.2 DRMS API Input data records Output data records DRMS Service = Session Master Record & Series Database SUMS
