Core Issues/Status 21 March 2002

Previous status report; Joanne's meeting  minutes   

Gaudi v9r0

Done! Heather report, perhaps including messy HTL stuff.

Facilities

New place for static functions, Util [Joanne]

static int facilities::Util::expandEnvVar(std::string* toExpand,
   const std::string* openDel = 0,
   const std::string* closeDel = 0);
 

[According to standard C++ practice, last two parameters should be const references: could you add such a variation?]

Constant Database issues

How do we specify (and how should we) constants ? Requirements are that they be visible (not wired into code), under version control.

• geometry: handled very well by detModel and the associated xml files in xmlGeoDbs
• digitization: thresholds etc. not geometry, but also in xmlGeoDbs. Retrieval by name with IGlastDetSvc::getNumericConstByName(std::string, double*)
• Algorithm parameters: need to be clearly associated with the algorithm and its version, so xmlGeoDbs is not the appropriate place.
  •  IFile, which reads an XML file.
  • joboptions.

Software development environment issues

• Release system -- Karl/Alex discussion

• vc++ 7.0. It works great!  Studio really much nicer. (Steve Ritz got his 1-month notice).

G4 transition: THB, Riccardo

Reminder: As of our workshop, all code relating to Gismo and instrument/IRF has been set aside. Big simplification!

• GlastSvc/GlastDetSvc, now does silicon plane geometry, using Leon's SiliconPlaneGeometry class.
• G4Generator:
  • McPositionHit: switch to relative coordinates for step position.
  • McIntegratingHit:  decision to use G4 to make subdivisions in Cal logs. (Almost?) Operational.
• GlastDigi: New algorithms:
  • TkrBariDigiAlg: Starting point for Bari fancy charge sharing.
  • TkrSimpleDigiAlg: final place for old geometric approach.
  • Note: No place yet to add noise, apply threshold, calculate TOT. (Old code thrown away.)
• Recon: Display detector, Si hits. [See pictures.] Implementation of IKalmanParticle using subset of old gismo code seems OK, needs testing.
