Procedures for submitting papers or presenting at conferences about ActivitySim work
Joe has not yet put together a proposed approach but anticipates the following:
Process would include guidance on notification and approval/consent.
Guidance on when a party would need to come to the consortium to ask for consent
If the presentation is substantially or primarily a reflection or documentation of work that the consortium is paid for, that definitely has to be brought to the consortium.
If it’s done by researchers and funding outside of the consortium, this doesn’t require consent but would be nice as a courtesy for our information.
If something is done entirely outside of consortium funding or members, we can’t expect any notification.
Suggestions from consortium members
Add a standing agenda item on a monthly basis to discuss any upcoming. ACTION ITEM: Michelle to do this.
Do we want more general presentations or add anything related to ActivitySim here (for example, Caliper used ActivitySim for some transmodeler)?
If activities funding by ActivitySim, definitely want them there
If it’s consortium member related, it would be nice to have
Caitlin wants presentations to put on AMPO website. ACTION ITEM: Michelle to maintain the presentation page and coordinate with Caitlin to populate the AMPO website with presentations, as provided and relevant.
ACTION ITEM: Michelle to requests ActivitySim-related presentations to include on Github and/or AMPO website.
ACTION ITEM: Michelle to add discussion about any potential topics for TRB AM to a future agenda
There was a question about whether we are allowed to use the term "ActivitySim" in a paper title for TRB, because of restrictions for using vendor names. We could make it implicitly obvious in the title, like “open-source activity-based modeling software”.
It looks like the preferred approach, right now, is the pydantic-like approach
ACTION ITEM: RSG will send Joe scope change text
2-Zone Memory Profiling (WSP)
Sijia presented responses to comments on 2-zone memory profiling documentation
PSRC did note that they tried the proposed short-term fixes related to memory usage and multiprocessing, and it did work. It takes experimenting to understand how many processors will make this work; it is machine-specific.
Joe proposes that we log this as an issue and then potentially go back and investigate why this works. ACTION ITEM: Sijia to create issue.
About a month until Sijia can provide results. She still needs to finalize the approach. There is a tentative plan to present at the beginning of July; Sijia to let us know if there is some strategy developed early, and she can provide an interim update. ACTION ITEM: Michelle to add this to the agenda about 6 weeks from now.
