Gamma-ray Large Area Space Telescope GLAST Large Area Telescope WBS 4.1.D SAS LAT Monthly Managerfest Richard Dubois LAT SAS Subsystem Manager
March - April Accomplishments • Flight Integration Support front and center • Current version of GlastRelease under test by I&T • System tests under construction; unit tests on LDFreader • Investigating bug/issues tracker to have in time to support config control of SAS tools • Working with Eduardo on delivery of calibration algorithms (end May) • Agreement from subsystems on update of geometry doc. • Calibration update user interface on track • OPUS pipeline • Database updating code done • Now working on batch interface/monitoring • One week slip expected to 1st week May • Refocused SciTools architecture design post DC1 • First iteration of architecture done • Developer walkthrough held last week • Starting HEASARC Network Monitoring with SLAC Computing Center • Now identified machine inside HEASARC to do file transfer tests • Thanks to Al Vernacchio for intervention! • Will provide long term understanding of file transfer speeds and reliability • Ground Systems proposing FastCopy as commercial tool for transfer • We offered SLAC’s bbcp as an alternative to consider
Getting to End of May • I&T stuff ready to try • Sim/recon, calib algs and infrastructure, pipeline • Investigating new technology for next iterations of major infrastructure products • Application servers; web services; Java; Enterprise Java Beans etc • In widespread commercial use; passed us by • SLAC data server • OPUS pipeline • Release Manager • System Tests • System tests are being used as proof of principle • “traditional” implementations of the others will be supported for I&T with transitions when sensible/transparent • Get bug/issues tracker in place • Initiate users windows server at SLAC
Key Milestones • End May – first delivery of SAS tool to I&T • Early June – kickoff I&T Analysis Workshop • Mid (?) July – 2nd Analysis workshop • Aug 4 – ISOC CDR • Aug 17-18 - GSDR • September - first hardware data analysis • Early 2005 – DC2 (depends on Flight Int work load)
Issues & Concerns • Delivery of calibration algorithms • Working with subsystems to make sure an adequate set happens • OPUS operating (have 3 weeks float to end May deadline) • Should be plenty of float for actual hardware • ScienceTools taking back seat; prep for DC2 will be harder if Flight Int takes significantly more resources • Need to know what support is needed from SAS for NRL env testing; Spectrum Astro, KSFC. “Porta-farm”? • Need to start ramping up compute resources at SLAC next FY • Is there money?
