Minutes[edit]

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

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[edit]

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
