Also I would like to know if I start 8 instances of command windows to run Phoenix miner on 8 gpus of the same rig, is there any performance penalty on that?
This is what I did for claymore right now. each miner takes -di # (# is a single digit between 0 to 7 representing 1 gpu)
8 instances of claymores, each mine to a unique eth addr.
If one gpu crashes the miner but didn't cause system hang, the other 7 conitnue working w/o restart. the crashed gpu would just restart automatically 30 second ~ 20 minutes late depending on how bad the situation is. If I start all 8 in one instance, it would restart all 8 gpus as many times as it could until the single crash one became stable.
As long as you have enough ram and processing power there shouldnt be a performance hit. If you dont have enough resources then yes.
Ill often run 2 instances of a miner on the same system. Four cards on claymore and four on Phoenix to test the differences over a few days. But I have more ram and processing power than a mining computer typically needs.
Thanks
Since I was able to run 8 instances of claymore in one computer, I assume I would have enough resource to do the same for phoenix then. I start 8 instance also for benchmark reason as well. Particularly I was able to measure the true output for different brand gtx 1070/1060 rx 580 gpus: eth/hour on a particular gpu.
Which nVidia driver version is consider to be good for Phoenix miner?
