announcements

evio version 4 is out unification of files, buffers, sockets details are hidden dictionaries have been added

new C++ standard current compilers have special namespaces boost, tr1 shared_ptr head's up

calorimeters physcis meeting, minimum blocks needed for form cluster make the default 1 change not made yet richard suggested threshold change

one cluster hits with loose timing cut Will will implement

bcal meeting last week irina and andre, discussion on how to incorporate sampling fluctuations into simulation more discussion single block, not layers

tracking

fdc segment code changed ot get target z position and lentgh from xml

matt tells reason for 65 was prevent

busy events cdc track candidate purious matches between layers 1 and 5 with nothing in 3

paul working on spiraling pions, going well, code running, doing tests, problem cases dealing with them

add a dpi+ and dpi- factory for each of those for convenience

committee has been named, chair no charge yet data acquisition added mcbride, mchaus, marchand, perske with another from babar and/or cleo discussions with chair understood how much work it takes to utilitze grid need to have numbers outlines of slides have been done intro curtis, cpu requirements, mark parallel, with hall b for two hours, 40 minutes of slides anyway, another meeting next week with rolf june 7 & 8 outline of document for TDR/hand-out
