Most scaling of STP thus remains ​O(N).
 These attributes are floats which can be "​attached"​ to a spike and which are also synced across nodes. Spike attributes are still under development,​ but I am putting some handwritten notes here to remind myself of how one can think of them being attached to individual spikes and how multiple attributes (imagine a single presynaptic [[NeuronGroup]] sends spikes via two different Connections with short-term plasticity to some downstream groups) are to be stored in the attribute buffer which is synced along with the spikes across nodes. These attributes are floats which can be "​attached"​ to a spike and which are also synced across nodes.
