I have only one 6990 card on board, but when I use aticonfig --list-adapters, I got:
* 0. 08:00.0 AMD Radeon HD 6990
1. 07:00.0 AMD Radeon HD 6990
and I run the miner:
./poclbm -u ** --pass ** -o ***... -d 0
this miner give me about 330 mH/s rate
but when I try to launch another miner, using device 1, I got error:
pyopencl.LogicError: clGetPlatformIDs failed: invalid/unknown error code
any suggestions? thanks.
How do I start one miner, then start the second miner, then the third, and then able to switch back to the first to check the progress?
Also, the miner should not quit when I exit the shell or SSH.
Help please, thank you guys
You will want to use screen.
I create two shell scripts, the first one is to start the miners for whatever pool I want to join and has my poclbm.py command line in it.
The second script is the script that starts all the miner script(s) that I created to start poclbm.
I then use screen like this:
screen -d -m -S gpu1 ./miner.sh
This starts a screen session named "gpu1" with the miner.sh script.
Then, to reconnect to that session, I use screen -r gpu1
To detach from that session, I use CTRL-A D
The miner will stay running even if you log out and when you log back in you can re-attach to that screen if you want, with screen -r gpu1
