It works on Windows as is but try to change --rpc-bind-port and --p2p-bind-port command line options:
./boolbd --data-dir dr1 --start-mining=1F9hbj8wp... --mining-threads=1 --rpc-bind-port=10102 --p2p-bind-port=10101
./boolbd --data-dir dr2 --start-mining=1F9hbj8w... --mining-threads=1 --rpc-bind-port=10112 --p2p-bind-port=10111
and so on. And don't forget to increment device_index starting from 0. Wait mining start before running next instance.
I have set thread_delay to 4000, but still does not work.
Is anybody else using latest beta 14.6 drivers?
Is there a way to manually start single instance with mining_threat=1 that would bind to 2nd or 3rd gpu? Perhapss using "device_index" field? Because in thatt case I would manually start 5 instances of miner.
