why every 16? is possible that change work during mining
Sorry, this doesn't make sense to me. Why isn't every hash submitted? My 8-core machine only had 5 and 13 hashes between the last two "[MASTER] work received", are they wasted? Sorry if these are slightly newbie questions, I have done pool mining before, I just want to know the meaning of these outputs, its a change from what xolokram's pts miner reports!
