I am using a Geth client with three GPU for mining, one ethminer per GPU connected through rpc. I would like to be informed when a new DAG period comes, because:
- GPU number 1 and number 2 should switch off manually.
- Restarting ethminer on GPU 0 allows me to generate the new dag.
- I can restart mining on all GPU.
How do you handle this transition? How you get notified?
