Fantastic post. Thank you for this. Here is heading a local.conf that works for ZenCash with global rules. This is for people who don't feel comfortable setting each GPU individually. I plugged all GPUs in at once and it worked right away. Of course replace with your own wallet address.
globalminer ewbf-zcash
maxgputemp 90
stratumproxy enabled
proxywallet znbByzymrCmWqoL6wn9QzZLeqSbvHK4Ktvn
proxypool1 luckpool.org:3057
flags --cl-global-work 8192 --farm-recheck 200
globalfan 85
I also read the Zen whitepaper and I am very impressed with the project. Good luck!
