Hi Crackfoo

My password line in my .bat file is:
c=BTC,x17=23,x16r=21,x16s=21,phi2=9.7,bcd=.028,lyra2z=5,phi=41,aergo=9.1,skein=.82,allium=10.7,lyra2v2=.0675,hex=.0175,lbk3=.44,polytimos=48,c11=33,x22i=12.3,sonoa=3.57,hmq1725=14.3,tribus=.131,bitcore=38

It selects bcd at the right times, but zpool (or yiimp) also reads bcd=.028 as d=.028 and sets that as difficulty. Other algos that come after bcd in the line above then also have difficulty set at .028

e.g. Currently mining x22i and from the zpool legacy website:

Details   Extra   Algo   Diff   ES**   Hashrate*
CryptoDredge/0.10.0   F,c=BTC,x17=23,x16r=21,x16s=21,p   x22i   0.028      7.8 MH/s
CryptoDredge/0.10.0   J,c=BTC,x17=23.5,x16r=21,x16s=21   x22i   0.028      5.7 MH/s
CryptoDredge/0.10.0   P,c=BTC,x17=23,x16r=21,x16s=21,p   x22i   0.028      4.1 MH/s

Can you please advise, thanks

There is a chance it could just be coincidence.

if you increase its normalization factor up to some arbitrary number (this will also influence your miner to swap to that algo, which helps us test quickly) lets say 0.28;  see if it indeed carries over to the difficulty setting.

If this is the case;  I would think someone screwed up a variable in the yiimp code by mistake....   seems like an easy enough variable to use by accident.


Yes If I set e.g. x22i to a high value and bcd to a low value so that it will always choose x22i, then it takes the value for bcd as the difficulty. I can change it at will:

-p c=BTC,x22i=120.3,bcd=.012

and on zpool it shows: CryptoDredge/0.10.0   P,c=BTC,x17=23,x16r=21,x16s=21,p   x22i   0.012      13.4 MH/s

and the miner also shows the same difficulty is being used: [05:49:37] INFO  - Setting new difficulty: 0.012

So, by changing the value for bcd in the password field I can change the difficulty it will use to mine other (not all) algos

Hoping that crackfoo will test and pass a message to yiimp devs (if they are still active)
