Project Meeting 2020.11.12

5b/6a Task 1 Project Management (milestone)

Oregon DOT is planning to multiprocess populationsim and add seed sharing for their statewide model and contribute the improvement
- Stefan reminded the team to say multiprocessing instead of multithreading and shared a link
- The statewide model runs multiple years into the future and runs for 50 to 60 PUMAs
- Plan to multiprocess by PUMA
- MetCouncil used seed sharing to add additional nearby PUMS samples to rural areas with not enough records in small markets
- What's the process for rogue contributions like this? How do they align with our roadmap and the managing contributions section of the Strategic Plan?
- These contributions sound good and are from trusted sources
- How do we decide how to share seeds - for now just used neighboring PUMAs
- Folks interested in the project should reach out to Alex
- Let's use this as a test case for a more formal review process
Discuss a few ActivitySim happenings - support for international users, commercial users, and potential new members

For the full scale Marin TM2 example, I corrected the drive transit issue and have traced a couple ODs to check results
Added ability to re-trace tap-tap calcs when pre-computed
I'm working through the set of review summaries we discussed
Jeff added a new submodel step - initialize_los - that pre-computes the tap-to-tap data
He's working on the shared memory data structures/access revisions for multiprocessing now
In response to Stefan's question last week, I drafted a DaySim PNR lot choice with ActivitySim page for discussion

Newman drafted the non-mandatory tour frequency interaction_simulate larch notebook
Newman working on wrapping it with a run_all_steps feature and also revising how the 8 EDBs by person type should be merged into 1 EDB like the other submodels
