SEMCOG model taking longer to run with 1.3 beta

[aletzdy]

The SEMCOG model (10%, single processed) takes longer to run with the current 1.3 beta (main branch) than the official 1.2.2 version.

I already presented on this issue last month. Adding this issue here with further log files. Key models taking longer: workplace location, non-mandatory tour scheduling, tour mode choice, and trip destination.

Hi @aletzdy, do you have the activitysim.log from the equivalent 1.2 run?

Updating this issue regarding runtimes with and without Sharrow. Below is the runtime comparison of runs with following characteristics:

• full sample,
• multiporcess (20 cores),
• max ram available 500Gb and,
• run on Intel Xeon Platinum machine
• Sharrow (blue) and non-sharrow (orange).

The runs were done last month using the main branch of ActivitySim, not camsys's sharrow-fix-all branch used for SANDAG example runs.

• Total Sharrow runtime: 252mins
• Total non-Sharrow runtime: 369mins

Workplace location is the main model taking noticeably longer under Sharrow.
