EDIT: On BFL's forums, some users are reporting > 100% efficiency with 5.5 GH/s miners. I thought reports here were that they don't work?
https://forums.butterflylabs.com/jalapeno-single-sc-support/3367-reducing-20%25-hash-rate-penalty-using-bfl-hardware-p2pool.html#post42224

Hi I'm that user on forums.butterflylabs.com talking about my jalepeno which works fine on p2pool, my current efficiency is 105%.  I'm not sure why the p2pool guide claims ASICs can't work on p2pool, it's working fine for me.  Once I get my 60GH singles in I'll be trying them there too so we'll see if they hold up as well.

It's odd, that's for sure.  You have 105% efficiency, but you also have a 20% DOA rate (which is horribly bad).  Not sure which number to believe...

Isn't 20% DOA pretty average for p2pool?

My GPUs (when I was still mining with GPUs) were getting <2% DOA.

He should give it a little more time. At "three sigma" confidence interval his stale+dead rate is (18.6 +- 10.2)%, so it could be just good luck.

4.8% DOA with ASICMiner USB

Edit: To be fair, I'm also running a p2pool backed mining pool[1], so that's probably why my DOA's are higher.

20% stale is OK. Local DOA must be no more than few percent with proper hardware (with miners in the same LAN where the node is). My AM USB gives 1.8% on localhost.

OK, so I've been looking at my orphans for the last 10 days or so.... about 33% of them occur after a block solve.

i guess i should also mention that 50% of them are orphaned by

1CTgYxMTY5j6SLytKeMsBWAXuUc6yNKcAe

and i know he isnt using an asic, so why so slow?

Been testing my upgraded Jally on p2pool after the reports that BFL asics seemed to be doing OK. After around 18 hours, I'm seeing this:



Efficiency seems OK? DOA is high though, should I be worried about that? Guess I will let it run a few more days and see how payouts go once we start actually solving some blocks.

Dear forrestv and p2pool node hosters,

I've made a patch which provides adaptive share and pseudoshare difficulty to the miners. I believe it might be useful to help miners with little hashrate and reduce load by enforcing high difficulty for fast miners.

Difficulty is controled by the new '-d' command line option which can have 3 values: A - adaptive, F - force adaptive, and D (or any other) - default. Default behaves just in the same way as the original version. Adaptive provides adaptive difficulty if the miner hasn't specified desired difficulty. Force adaptive provides adaptive difficulty in any case (user's desired values are ignored).

Difficulty is calculated for each username based on its hashrate according to these target rates:
- 20 shares per min(estimated time to block, chain length * share period)
- 20 pseudoshares per 10 minutes
(per user)

Source: https://github.com/baloo-kiev/p2pool-adaptive
Test node: 78.27.191.182:8349

It's about 30 lines of code (commented where necessary).
Diff: https://github.com/baloo-kiev/p2pool-adaptive/commit/10e59b9564740c6b039380b5b86fdf8071543f48

Also, I've just found out that share difficulty has upper limit of 10 times current minimal difficulty. It is set by line 123 in p2pool/data.py
Code:
bits = bitcoin_data.FloatingInteger.from_target_upper_bound(math.clip(desired_target, (pre_target3//10, pre_target3)))
So I'd like to know what's the reason for this limitation and whether it can be changed to generate shares with even more difficulty.

How do you know it was that address, and is it wrong to assume that you have his ip address? If so ban him don't send any more work his way. Not that it matters but that address has a huge balance by the way...

I'm seeing only 84% efficiency with mine. What settings are you using? My miner name has +256 appended to it. A poster in the BFL forums is using /6000 and is getting results more like yours than mine. Given that share difficulty is only 1080 as I write this, though, wouldn't setting difficulty too high risk throwing out valid shares?
