Hi All,

Following Haiwangs's presentation at the simulations meeting today, I made some performance plots for tracking with the TPC cell size doubled. I posted them on the simulations meeting page:

https://indico.bnl.gov/materialDisplay.py?contribId=2&materialId=slides&confId=2701

The file name is:

double_tpc_cell_size_tests_july11_2017.pdf

The bottom line: the performance is very good. The TPC simulation parameters should be re-optimized carefully to match the larger cell size, but this reduces the standalone tracking memory usage for a central Hijing event from 15-20+ GB to less than 7 GB.

Cheers

Tony
