What I've learned...

1) getting this compiled and working can be a bit of a chore.  I worked around some seg faults and openCL errors, and tested a million thread/intensity/worksize options.

2) my cards seem to like rawintensity @ 960, with 8 worksize

3) minergate only accepted 40% of my shares, piece of crap.  Moving on...

4) monerohash.com had 100% share accept, but require 7 XMR balance to withdraw to an exchange (using -u Base.PaymentID).  That doesnt work for me.  Moving on...

5) dwarfpool had 100% share accept.  Only downside is 2% pool fee.   Still considering other options...

So this is where I am ATM in my Monero GPU mining on linux journey...  hope you find it useful.
