Chama Meeting 8/18/2023

Meeting Notes​

  • Anne might need some Arduino support, short little office hours help at some point.

  • May Fly board with Arduino environment.

  • Conclusions section in our OneNote pages.

  • Anne's original thought of Ensemble was "multiple INP files".

    • Ensemble of multiple SWMM runs results in a single Chama run.
    • All plumes have the same probability.

  • Way to optimize memory to avoid the signal file generator issue.

  • Winter (sp) didn't have any issues.

  • Could be output timestep and run timestep difference? We've addressed that already.

  • We don't need to worry about DEM at this time and can assume flat ground.

  • Puff probably isn't a good fit. That's more for regular pulses of output?

  • They'll ask ___, a modeler, about what use case puff might be used for.

  • Plume makes the most sense.

  • Data visualization, such as showing on OL map, would be secondary priority. Anne is more interested in the end results of the opt, not necessarily looking at a map of the plume.

  • Office hours with Anne and Lifeng after I get an HPC test going on RHEL 8 (updated server).

  • Chama has only been run on HPC in the context of our work, when Lifeng ran it last batch. No one else in EPA is doing anything like this.

  • Winter hasn't been run on the HPC.

  • Writing SWMM INP file out with PySWMM or alternative Python package API

  • PySWMM doesn't currently have an export INP file option and they don't plan to add it to the new one. This addition would be a couple years down the road.
