PBM without the penalty

[acos0874]

Is there a way of preventing a coin being mined except for when it is considered for post block mining?

[RainbowMiner]

Good question. I'll check :)

I realised I responded in the wrong thread. Thanks again!

[RainbowMiner]

Oh, me too 🍭

With the next release, the parameter "CoinSymbolPBM" in pools.config.txt will work as expected, even if there is only one pool for the coin's algorithm selected:

If you put a coin symbol onto the "CoinSymbolPBM" list, this coin will idle on the corresponding pool, until the post block mining condition is met.

[acos0874]

Final request though. Is there some way of introducing a PBM hysteresis in the same way you did with the miners and the pools? I think this would be the cherry on top of the PBM setup.

[RainbowMiner]

I think, that cherry already exists in coins.config.txt, parameter "MinProfitPercent":
switching to postblock mining only, if the post block miner's profit is at least MinProfitPercent % of the best miner's profit.
Can also be set to values greater than 100%

[acos0874]

Yes I do use that however what actually ends up happening is that as that PBM ignores the switch prevention I get a lot of chopping between nicehash and PBM as soon as one becomes slightly more profitable than the other.

As an alternative to using an hysteresis it might be effective to have the miner lock to a coin when PBM is detected. Although of the two options I think this would be less desirable

[acos0874]

Here's how it looks when it's switching too much. It seems to ignore both the switch prevention and minimum mining intervals. I would be happy if it would obey the minimum mining intervals which I could set to a higher number.

It also seems that pbm is still based on revenue not profit, although I'm not entirely sure.
