jack2_split breaks the serial dependency by
registering two jack clients
which respectively only have terminal input and output ports. It copies
the buffers from its inputs to its outputs after the current process
cycle. This introduces one additional period of latency into the graph,
but allows jack2/jackdmp to schedule A and B in parallel (e.g. on two
cores).
A few comments:
* Doesn't jack2 have this built-in ? I seem to remember something called
'loopback ports', but it has been some time...
So you start jack2 with the required number of loopback ports, then
connect A -> writable side of loopback ports, and readable side -> B.
* Since this is just a buffer, the '-split' name seems a bit misleading.
* I'm not convinced that the logic used in your current implementation
will do the right thing in all cases (but I could be mistaken).
The reliable way to organise this would be to use a dummy port in
reverse direction on both clients and connect those.
