Agenda

  • NEURON News (3 min)
  • A new versioning scheme for NEURON (7 min)
  • Software Engineering of NEURON codebase: (5-10 mins)
    • practicalities
    • How / When
    • Which parts to start with : HOC/NMODL/Solver/legacy libraries
  • Technical discussion on issues:
    • What to do about readline? (see issue #451). A tentative solution is in branch nrn-rl-getc .
    • Sundials v 5. Very different NVector for threads and mpi. NEURON currently uses homemade implementations for these. See branch cvode3. A subbranch, idainit, is much more robust for IDA initialization but comes at a cost of an extra algebraic variable for each extracellular layer, i.e. vm = vi - ve .
    • The newabi3 branch is stuck. See issue #338 . The latest CYTHON that supports translation with #define Py_LIMITED_API generates many errors during compilation of the CYTHON \*.cpp files generated from the *.pyx files in the rxd module.
  • git/github mini-tutorial 2:
