Hi,
Thank you for making this miner.
I would like to know if your miner supports multiple instances. I have 12 cards and would want 2 instances of your miner running simultaneously with 6 cards accessible for each instance. Reason for doing this is to increase probability of getting shares.
Could you comment if this is possible, how to achieve it and if it will yield the benefits I stated?
Thank you and more power to you and your team.
John
Run -gpus 123456 on one instance (or other indexes of your preference/need) and -gpus 7,8,9,10,11,12 on another instance.
Still, I agree with ANewMiner, I do not believe it will increase profitability or share increase.
Keep in mind that PhoenixMiner shows which actual difficulty it took to find the share, greater difficulty equals greater payment from the pool. So bigger number of shares does not mean more profit.
Though honestly, that is one test I haven't even thought to try myself. Please report back your findings

How to use -gt (GPU tuning, what does it do)? I dont seem to find any value that would make a difference.
It does, in my case the difference is very slight for each change, also, the change take some time to kickin, it takes patience to tune the gpu's this way.
Running HWiNFO v5.72 in the background I lose 1-2 mh/s ... it's just me ?
I thought it was me, with your comment plus the previous answer from Phoenix team, it makes sense to me that reading the gpu directly take some processor's time, HWiNFO does this while running the sensors. What I did was to tweak the interface to not only hide the items I want to see (mostly Memoty Errors) but also uncheck "monitoring".
Hope that helps
