See instructions in https://github.com/bjhardcastle/lazynwb/CONTRIBUTING.md and the original template: https://github.com/bjhardcastle/copier-pdm-npc/blob/main/README.md

notes

  • hdf5 access seems to have a mutex lock that threads spend a long time waiting to acquire (with remfile)
  • seems to slow down over time in single-threaded loop
    • on laptop, first 5 are fast (2-3 s per iteration) - successive iterations are much slower (>60 s)
