Macro Definition Documentation

SYNCBUFFER_DELTA_DATATYPE

#define SYNCBUFFER_DELTA_DATATYPE   NeuronID

Datatype used for delta computation should be a "long" for large nets with sparse activity otherwise NeuronID.

To strictly guarnatee flawless function this datatype needs to be larger than max(NeuronID)*MINDELAY to avoid an overflow and undefined behavior.

SYNCBUFFER_SIZE_HIST_LEN

#define SYNCBUFFER_SIZE_HIST_LEN   512

Accumulate history over this number of timesteps before updating the sendbuffer size in the absence of overflows.

SYNCBUFFER_SIZE_MARGIN_MULTIPLIER

#define SYNCBUFFER_SIZE_MARGIN_MULTIPLIER   5

Safety margin for receive buffer size – a value of 3 should make overflows rare in AI state.
