2. GLAST LAT Project LAT Monthly Apr 14 2004 - SAS 2 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

3. GLAST LAT Project LAT Monthly Apr 14 2004 - SAS 3 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

4. GLAST LAT Project LAT Monthly Apr 14 2004 - SAS 4 Key Milestones  End May – first delivery of SAS tool to I&T  Early June – kickoff I&T Analysis Workshop  Mid (?) July – 2 nd Analysis workshop  Aug 4 – ISOC CDR  Aug 17-18 - GSDR  September - first hardware data analysis  Early 2005 – DC2 (depends on Flight Int work load)

5. GLAST LAT Project LAT Monthly Apr 14 2004 - SAS 5 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?
