I'm using rpcminer-cuda to have a play around mining some bitcoins. I have 2 NVidia cards, and I understand this is not ideal for any profitable mining. I would however like to have them both working at the same time. Presently the output from rpcminer-cuda when it starts up is:
rpcminer-cuda.exe -url=myurl -user=myuser -password=password Client will start 1 miner threads 2 CUDA GPU devices found Setting CUDA device to first device found
How do I make it use both cards at the same time? Do I need to tell it to start two threads or is there some other commandline switch I need to use? I've tried adding -gpu=2 but it seems to be ignored.
