Here we discuss topics that need broader attention, for example questions that came up but are outside a single project's scope, larger planned changes/PRs that affect all teams or pending work that is blocked by external factors.

(Presentation by @akorgor and [@jespinoza])
Is it possible to prevent delivery of (specific) secondary events?
- currently update once per time-step is quite wasteful
- looked into delivery of secondary events
- communication code could maybe provide suitable mechanisms for different time interval communications
Is it possible to declare "shared" variables that can be used by neurons and synapses?
- similar problems in the Urbanczik-Senn model where certain values need to be equal in neurons and synapses
- maybe implementation of "shared" variables could be done in the kernel (?)
- NESTML could make sure that implementation is always consistent
- depends on the nature of the variables, especially if the implementation is in the neuron or synapse properties
- could also be a kernel property (get/set kernel status), similar to Structural Plasticity Manager, set in dictionary from one place, read out on the others.
- currently much of the users interaction is on the level of front-end dictionaries (Python)
Is it a problem that the only supported time resolution is 1 ms?
