--- Comment #1 from Jolan Luff jolan@jolan.org --- The program in question is "Claymore's Dual Ethereum+Decred/Siacoin GPU Miner v5.0 (Windows/Linux)":

I have it running on 5 computers on 8 cards total and some single GPU setups hit it only sporadically, I have a dual GPU system where the program is basically unusable, but in general the program still works despite some slow down due to thousands of errors being generated and printed.
