I'm not sure whether you've found the solution or not, but just in case another person comes by this post, then this will be help for them too.
To set the gpu used with the rpcminer-cuda of GUIMiner, you just specify it in the "flags" box. Put "-gpu=0" for the first GPU, and "-gpu=1" for the second GPU and so on...
Topic: How to enable GUIMiner on my 2nd CUDA card (Read 782 times)
I have two GTX 580 cards. I realize that it is not efficient to mine with them, but I have to heat my apartment anyway and I game with them, so I might as well use them to mine when I'm not gaming.
When I start a CUDA worker in GUIMiner, I get:
2012-11-25 08:57:51: Listener for "CUDA MINER": 2 CUDA GPU devices found
2012-11-25 08:57:51: Listener for "CUDA MINER": Setting CUDA device to first device found
I have searched this forum and google for an hour now and cannot discover how to utilize the second CUDA device. Any suggestions?
