Setting num_parallel=2 does not work on two rasps

I have two rasps (different ips) connecting to the tracker, and I also set up num_parallel to two in the autotune script, while only one of them is working and another one keeps sending “INFO:RPCServer:no incoming connections, regenerate key”. Do I have to do extra setups?



That should not be the case even if num_parallel is one, as the tracker should use alternating PIs. What are the device keys that you are using for each device?

You can try to restart all of them and see whether you can get two “free” rasp on the queue status.

Find the problem, thanks for you info!

It is actually caused by my SSH tunneling configurations, not your codes.

@Jokeren how did you solve this issue? In my host machine, when I query, I can see multiple devices are registered but only one is used during tuning, the other one returns INFO:RPCServer:no incoming connections, regenerate key ...

@gasgallo, sorry I haven’t been working on this for two years.
