GLAST Large Area Telescope: Gamma-ray Large Area Space Telescope GLAST Large Area Telescope: I&T Weekly Meeting I&T/Online May 5, 2005 Ric Claus Online Manager SLAC
Online activities All of Online personnel observe Cleanroom operations Everyone attends the 3:15 meeting Learning about non-reported problems Trying to find ways to reduce Operator Error Beyond 2 towers Housekeeping multi-pen strip chart GUI Parallelizing INT scripts Trying to move some LATTE 5 features into production earlier (e.g., HSK, LATc) More design work on LCI method of test script structure E-logbook Brian requested ability to search shift logbook Quickly provided with Google Desktop Stand-alone e-logbook issue? Implementing requested improvements
Online progress LATTE 4.9.0 CCB JIRA number 34 GPIB support for Agilent power supply (Brian) RS-485 support for BPU Simpson meters (Brian) FSW multi-tower PIG bug (Lester) FSW PIG behavior provides source of OE for Testers ACD (ancient) GASU problem (Jim provided work-around and a fix for LATTE) LTE-254: SW verification passes, but in elog, the SW shows red. Fix this inconsistency (Brian) LTE-251: If rcReport generation fails, wrong rcReport line is extracted from rcReport.out during export LTE-257: Message logger does not launch More?
Online progress LATTE 5 Exposing VSC interface to Python Trying to pin down the core architecture Having difficulty compiling combined LATTE & FSW in any Windows environment Visual Studio CygWin MinGW Jim: “It doesn’t look good.” Still some wiggle room, but he’s discouraged Move to Linux? Build with multiple compilers and tie EXEs together with network code (cumbersome, performance hit, extra work and maintenance)
