People present at Meeting:
==========================
Ursula Bassler, Allan Bross, Sailesh Chopra, Brian Connolly, Bill Cooper,
Pierre Detoeuf,   Hal Evans, Stefan Gruenendahl, John Hobbs, Rick Jesik,
Patrick LeDu,  Jim Linnemann, Stephan Linn,  Manuel Martin,  Wendy Taylor, 
Jian-Ming Qian,  Silvia Tentindo-Repond,  Horst Wahl, Armand Zylberstajn. 

1. Trigger simulation (Silvia Tentindo-Repond)
   Silvia gave an update on the trigger simulator status -- not much progress
   since last STT meeting
   
2. processor for track fitting:
   John Hobbs: decide against use of Alpha processors;
     reason: * needs lots of rack space which puts too much 
               constraint on others 
	       (concerns confirmed in discussions with DeanS)
	     * possible gain in speed not significant enough vs complications
	     * hope to get further improvement in time for FPGA algorithms
	     
3. CTT broadcasting:
   scheme proposed by Manuel Martin & Co is accepted;
   open questions:
        - how to deal with duplicate tracks due to overlap? 
	   tag tracks in overlap region as possible candidates for doubles?
	   can we deal with the additional bandwidth requirement?
	      (but note it is only 10% increase)
	      
	  Manuel will continue to look for ways of eliminating duplicates.
	  
4. Queueing:
   Stephan Linn has been trying to get permission from IBM to copy RESQ to SCRI,
     so far unsuccessfully. RESQ is unsupported and only runs under an obsolete
     operating system on very slow computers at U. Maryland -- need to look for
     alternatives. Ptolemy is a candidate (is shareware, available for free).
