10 years ago Update: I had removed the parameters for cards 4 and 5 from the config... leaving the six tc, engine and mem parameters in avoids the startup error, but the two cards still show up as OFF and trying to start another sgminer for just cards 4 and 5 (once the first instance is up) results in more errors and a segfault.

10 years ago More testing ... using the same sgminer.conf for all three instances but passing -d 0,1 to the first, -d 2,3 to the second and -d 4,5 to the third. This is the same sgminer.conf that works with all six cards on the same sgminer (no -d arguement).
This first instance (-d 0,1) starts up but seems to be accessing fan RPMs and temperatures for cards it isn't supposed to be using:

--------------------------------------------------------------------------------The second instance (-d 2,3) complains about bad configuration parameters but actually starts up however the RPM for the cards "owned" by the first instance still show up and it seems like the second instance is fighting the first on fan settings causing the fan RPMs to fluctuate high-low-high-low-etc.

10 years ago Semi-OT note: to work around editing your user name out, you could try --incognito on CLI (or [D][I] in ncurses UI). This should work on latest git master (and I hope https://github.com/veox/sgminer/issues/123 is fixed).
EDIT: Somehow missed this part:
This is with the nfactor branch
So the above proposal will only work if nfactor is merged into master (or the other way around; locally is enough, of course).
I have six GPUs on a single machine and wanted to run one instance of sgminer for gpus 0-3 and one for gpus 4 and 5 so that I could mess with configurations without impacting all 6. Using -d 0,1,2,3 to start the first sgminer instance resulted in sgminer still running with gpus 5,6 but using bad values for the config resulting in them showing up but being in the OFF state:
This is with the nfactor branch
( I have no fans on 4 and 5 due to oil immersion... that is why there are no RPM readings for them )
