Attendees: David L. (chair), Simon T., Adesh S., Sean D., Mike W., Cristiano F., Justin S., Curtis M.

Benchmarking Status

  • Cristiano has started using the janadot plugin to look at benchmarking various factories using recent data
  • David continues work on new event parser
    • Factor of 4 speedup occurs in parsing code if linking of associated object is turned off
    • Some options for optimization there including replacing associated object linking with copying the few needed relevant parameters

Simulation Status

  • Adesh spoke with Mark I. and concluded that the sim1 run has significant differences from the target priority data set
  • This is in addition to the much higher photon energy threshold needed for L3 trigger studies
  • Adesh will start producing a dedicated L3 simulated dataset next week. Asked if Justin had any guidance as to how much would be needed
    • Justin suggested starting with 10M events and going down to the 2π production threshold in photon energy
  • Sean asked if we could think of any features that could be added to mcsmear that would help with the L3 simulation studies
    • No specific suggestions were given, but we will think about it offline and convey anything we come up with to him offline. He is currently undergoing a significant rewrite of mcsmear so now would be the best time to get additional features put in
