Stratum diff always confused me. Some pools report it as fractional numbers, some much lower than 1, those which I usually go for.
There are two sgminer issues,
#312, later superseded by
#317 regarding this.
Just to make sure we're talking about the same thing, I have been using sgminer-5.1-2014-12-20-win32.zip I just downloaded from nicehash and pointed it to Myriadcoin nonce-pool (stratum: mine1.myr.nonce-pool.com:3360).
Noncepool uses difficulty 2 (at least that's what's reported in workers control panel and that's also what goes off stratum).
Of course this is totally inappropriate to a small 1MHs miner such as me.
The cool thing is that due to a bug in my miner's diff calculation (this time I'm really talking about mine) I've been submitting work anyway... and it gets accepted anyway (well, it used to). I am not sure if I'm more
,
or
So, let's go back to sgminer.
In line of concept, I fully agree with badman and lukejr when they propose the diff multiplier to be deprecated and removed.
In practice, it seems to me the pool operators are taking it a bit too easy as I cannot believe those to be sensible settings.
On the pro side, p2pool nodes seem to work as expected so far... perhaps NOMP as well, I don't know. What's the state of this thing?
